BIOMETRIC SYSTEMS, DESIGN AND APPLICATIONS Edited by Zahid Riaz. pot

Traditional recognition systems have the abilities to recognize the human using various techniques like feature based recognition, face geometry based recognition, classifier design and model based methods. In Zhao et al. (2003) the authors give a comprehensive survey of face recognition and some commercially available face recognition software. Subspace projection method like PCA was firstly used by Sirvovich and Kirby Sirovich & Kirby (1987) , which were latterly adopted by M. Turk and A. Pentland introducing the famous idea of eigenfaces Turk & Pentland (1991). This chapter focuses on the modeling of human face using a three dimensional model for shape model fitting, texture and temporal information extraction and then low dimensional parameters for recognition purposes. The model using shape and texture parameters is called Active Appearance Model (AAMs), introduced by Cootes et. al. Cootes et al. (1998)Edwards, Taylor & Cootes (1998). For face recognition using AAM, Edwards et al Edwards, Cootes & Taylor (1998) use weighted distance classifier called Mahalanobis distance. In Edwards et al. (1996) the authors used separate information for shape and gray level texture. They isolate the sources of variation by maximizing the interclass variations using discriminant analysis, similar to Linear Discriminant Analysis (LDA), the technique which was used for Fisherfaces representation Belheumeur et al. (1997). Fisherface approach is similar to the eigenface approach however outperforms in the presence of illuminations. In Wimmer et al. (2009) the authors have utilized shape and temporal features collectively to form a feature vector for facial expressions recognition. These models utilize the shape information based on a point distribution of various landmarks points marked on the face image. Blanz et al. Blanz & Vetter (2003) use state-of-the-art morphable model from laser scaner data for face recognition by synthesizing 3D face. This model is not as efficient as AAM but more realistic. In our approach a wireframe model known as Candide-III Ahlberg (2001) has been utilized. In order to perform face recognition applications many researchers have applied model based approach. Riaz et al Riaz, Mayer, Wimmer, Beetz & Radig (2009) apply similar features for explaining face recognition using 2D model. They use expression invariant technique for face recognition, which is also used in 3D scenarios by Bronstein et al Bronstein et al. (2004) without 3D reconstruction of the faces and using geodesic distance. Park et. al. Park & Jain (2007) apply 3D model for face recognition on videos from CMU Face in Action (FIA) database. They reconstruct a 3D model acquiring views from 2D model fitting to the images.

Figure 35. Graph between ‘calculated seasonal index’ and ‘average index’ of ‘Sales’ dataset 6. Conclusion The book chapter presents a unified data mining theory and then the mathematical formulation of the unified data mining theory (UDMT). The data mining processes; clustering, classification and visualization are unified by means of mathematical functions. The chosen data mining algorithms are proved to be as functions i.e. the algorithms are used as functions. The first function takes the set of data as input, applies K-means clustering data mining algorithm and produces the set of clusters as output. The second function takes the set of clusters as input, applies the C4.5 (Decision Tree) data mining algorithm and produces the set of rules as output and finally the third function takes the set of rules as input, applies data visualization data mining algorithm and produces the set of 2D graphs as output. The functions are the mappings from the set of data to the set of clusters to the set of rules to the set of 2D graphs. From the set of 2D graphs one can interpret and evaluate the results to discover the knowledge i.e. the knowledge is extracted from the given dataset through the unified process of the composition of clustering, classification and visualization followed by interpretation and evaluation of the results. Thus, we attempt to unify the processes of data mining life cycle. In summary we can say, first pass the set of data through the composition of clustering, classification and visualization and then the obtained results are interpreted and evaluated to extract the knowledge. The proposed unified data mining theory covers all the pertinent essentials of the unified theory i.e. generates truly applicable explanations and predictions of the real world problems and does not contradict itself, therefore, we can say that it is comprehensiveness, precise, consistent and correct. The UDMT is tested on variety of datasets and the knowledge is discovered through the unified processes of data mining. On the basis of UDMT, a tool namely; UDMTool, multiagent systems, is developed, which takes dataset as input and

If (U, Ω) is a paired set, then for every element u in U , we denote by u e the element that belongs to the same pair as u and is distinct from u. Consider a pair of 2-matroids, Q 1 = (U, Ω, r 1 ) and Q 2 = (U, Ω, r 2 ), defined on the same partitioned set (U, Ω). Set R = r 1 + r 2 . Then P = (U, Ω, R) is a parity system, which we call the sum of Q 1 and Q 2 . Furthermore a solution to Problem 3.8 for P will give rise to a solution to Problem 2.7 for Q 1 and Q 2 . We shall be especially interested in the case when P is a sum of a 2-matroid Q = (U, Ω, r) and the converse 2-matroid Q e = (U, Ω, r), where e r e is defined by the relation r(A) = e r( A), for every subtransversal e A of Ω.

(c) Figure 10: Octave distribution over three frequency bands for a rock signal. To further improve the discriminatory power of this parameter the distribution of this parameter is grouped into three frequency bands 0–5 kHz, 5–10 kHz, and 10–20 kHz. This is done since analyzing the audio signals in subbands will provide more precise information about their audio characteristics [ 49 ]. The bounds for frequency bands were arrived considering the fact that most of the audio content lies well within 10 kHz range so this band needs to be looked more in detail hence broken further into 0–5 kHz and 5 kHz to 10 kHz and the remaining as one band between 10 kHz to 20 kHz. By this frequency division we get an indirect measure of signal envelope contribution from each frequency band. From Figure 9 even though we see di ff erence in the distribution of octaves between rock-like and classical music, it becomes more evident when the distribution is divided into three frequency bands as shown for a sample rock and a classical signal in Figures 10 and 11 . Dividing the octave distribution into frequency bands basically reveal the pattern in which the temporal structures occur over the range of frequencies. As music is the combination of di ff erent temporal structures with di ff erent frequencies occurring at same or di ff erent time instants, each type of music exhibit a unique average pattern. Based on the subtle di ff erences between patterns to be detected, the division of octave distribution over fine frequency intervals and the dimension of the feature set can be controlled.

In this normalization process, differences in sample sizes used to generate the matrices are eliminated and therefore, individual cell values within the matrix are directly comparable. In addition, because as part of the iterative process, the rows and columns are totaled (i.e., marginals), the resulting normalized matrix is more indicative of the off-diagonal cell values (i.e., the errors of omission and commis- sion). In other words, all the values in the matrix are iteratively balanced by row and column, thereby incorporating information from that row and column into each individual cell value. This process then changes the cell values along the major diagonal of the matrix (correct classifications), and therefore a normalized overall accuracy can be computed for each matrix by summing the major diagonal and dividing by the total of the entire matrix.

4.3 Analysis of Object Actions and Interactions The objects are classified into persons and vehicles based on their footage area. The interaction among persons and vehicles can then be analyzed at semantic level as described in [29]. Each object is associated with spatio-temporal interaction potential that probabilistically describes the region in which the object can be subsequent time. The shape of the potential region depends on the type of object (vehicle/pedestrian) and speed (larger region for higher speed), and is modeled as a circular region around the current position. The intersection of interaction potentials of two objects represents the possibility of interaction between them as shown in Fig. 12a. They are categorized as safe or unsafe depending on the site context such as walkway or driveway, as well as motion context in terms of trajectories. For example, as shown in Fig. 12b, a person standing on walkway is normal scenario, whereas the person standing on driveway or road represents a potentially dangerous situation. Also, when two objects are moving fast, the possibility of collision is higher than when they are traveling slowly. This domain knowledge can be fed into the system in order to predict the severity of the situation.

This observation has led to a commonly used technique to detect attacks in so- called signature-based intrusion detection systems such as Snort. The idea is that a router or monitor has a set of rules, much like classifi ers. However, the Snort rules go beyond classifi ers by allowing a 5-tuple rule specifying the type of packet (e.g., port number equal to Web traffi c) plus an arbitrary string that can appear anywhere in the packet payload.

There are several limitations in this study. First, we lim- ited our study to time-domain features. The implementa- tion of frequency and time-frequency domain features with other types of classifiers is worth investigating in the future. Another limitation is that muscle fatigue during use of EMG-based HMIs is mainly due to repetitive, long- term muscle use; the muscle fatigue in this study was intensity-induced (short-term) because of the time con- straints for conducting the experiments. Additionally, because the level of muscle fatigue was not controlled across subjects, some subjects demonstrated very low level of muscle fatigue and slight changes in EMG signals. Based on the results of this study, relying only on "opti- mal" EMG features is not sufficient to overcome the vari- ations in EMG signals caused by the considered disturbances. Additional solutions, such as effective training strategies and adaptive pattern recognition [16], are promising, although the challenges in making these potential solutions clinically viable still exist. Continued engineering effort is demanded towards development of a practical and robust HMI based on EMG pattern recog- nition.

Advanced DNA fingerprint genotyping based on a model developed from real chip electrophoresis data

Advanced DNA fingerprint genotyping based on a model developed from real chip electrophoresis data

Large-scale comparative studies of DNA fingerprints prefer automated chip capillary electrophoresis over conventional gel planar electrophoresis due to the higher precision of the digitalization process. However, the determination of band sizes is still limited by the device resolution and sizing accuracy. Band matching, therefore, remains the key step in DNA fingerprint analysis. Most current methods evaluate only the pairwise similarity of the samples, using heuristically determined constant thresholds to evaluate the maximum allowed band size deviation; unfortunately, that approach significantly reduces the ability to distinguish between closely related samples. This study presents a new approach based on global multiple alignments of bands of all samples, with an adaptive threshold derived from the detailed migration analysis of a large number of real samples. The proposed approach allows the accurate automated analysis of DNA fingerprint similarities for extensive epidemiological studies of bacterial strains, thereby helping to prevent the spread of dangerous microbial infections.

Single-based authentication system seems unable to monitor and authenticate effectively due to easy to hack and break out. Since that, the introduction of Radio Frequency Identification (RFID) has taken place as an alternative to the previous authentication systems such as biometrics and bar code system as well as smart card technologies. However, the integration of those technologies is expected to provide an effective monitoring system and a very high secured system that can perform and monitoring to mitigate the ratio of unauthorized person access. Nowadays, the trend of RFID is clear that the technology is playing an essential role especially in various field such as in engineering, medical, business, construction (Corporation, 2005; EraBuilder, 2006), library (Shahid, 2005), farming management (Bakery, et al., 2007) and etc. Several methods and technologies have been used to develop monitoring systems.

6.1.2. Error Expectation for Boosting. In traditional super- vised settings we are provided with a set of examples and labels, which constitute our training set, and thus it is possible to apply algorithms such as boosting. However, this becomes problematic when labels are noisy; (see, e.g., [ 35 ]). Such an example is a typical speech recognition data set. Most of the time such a data set is composed of a set of sentences, with a corresponding set of transcriptions. However, while the transcriptions may be accurate as far as the intention of the speakers or the hearing of the transcriber is concerned, subsequent translation of the transcription into phonetic labels is bound to be error prone, as it is quite possible for either the speaker to mispronounce words, or for the model that performs the automatic segmentation to make mistakes. In such a situation, adapting a model so that it minimises the errors made on the segmented transcriptions might not automatically lead into a model that minimises the word error rate, which is the real goal of a speech recognition system.

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Analysis of nonstationary signals, such as music signals, is a challenging task. The purpose of this study is to explore an e ffi cient and powerful technique to analyze and classify music signals in higher frequency range (44.1 kHz). The pursuit methods are good tools for this purpose, but they aimed at representing the signals rather than classifying them as in Y. Paragakin et al., 2009. Among the pursuit methods, matching pursuit (MP), an adaptive true nonstationary time-frequency signal analysis tool, is applied for music classification. First, MP decomposes the sample signals into time-frequency functions or atoms. Atom parameters are then analyzed and manipulated, and discriminant features are extracted from atom parameters. Besides the parameters obtained using MP, an additional feature, central energy, is also derived. Linear discriminant analysis and the leave-one-out method are used to evaluate the classification accuracy rate for di ff erent feature sets. The study is one of the very few works that analyze atoms statistically and extract discriminant features directly from the parameters. From our experiments, it is evident that the MP algorithm with the Gabor dictionary decomposes nonstationary signals, such as music signals, into atoms in which the parameters contain strong discriminant information su ffi cient for accurate and e ffi cient signal classifications.

In the past, signal-type identification relied mostly on operators scanning the radio frequency spectrum with a wide-band receiver and checking it visually on some sort of display [ 1 ]. Clearly, these methods relied very much on the operators’ skills and abilities. These limitations then led to the development of more automated modulation recogniz- ers. One semiautomatic approach was to run the received signal through a number of demodulators and then have an operator to determine the modulation format by listening to the output of each demodulator. This approach is however not very practical anymore due to the new digital techniques that transfer both voice and data. Then techniques for au- tomatic signal-type identification started to emerge.

In the present study, five sol- vents of different polarities (water, methanol, ethanol, chloroform, and n-hexane) were evaluated with regard to their extraction efficiency.

Therefore, face presented for recognition to these approaches should be e ffi - ciently segmented, that is, aligned properly to achieve a good recognition rate. The shape of the face di ff ers from person to person. Segmenting a face uniformly, invariant to shape and pose, suitable for recognition, in real-time is therefore very challenging. Thus, face segmentation “online” in “real-time” sense from a video sequence still emerges as a challenging problem in the successful implementation of a face recogni- tion system. In this work, we have proposed a method which accommodates these practical situations to segment a face ef- ficiently from a video sequence. The segmented face is then handed over to a recognition algorithm based on principal component analysis and linear discriminant analysis to rec- ognize the person online.

The design equations for the components of the active matching network can be readily extracted from [3, 4] as follows. To design the active matching network, we first fit the antenna impedance to a simple model. Since the antenna is an electrically small monopole, the real part of the antenna impedance is assumed to vary as the square of frequency, and the imaginary part is modeled as a series LC.
