... proposed approach, (c) the Canny edge detector [1], (d) single-scale surround inhibition [54], (e) a modification of the multiscale edge detector CARTOON [45], and (f) a multiscale contour detector ... presented and discussed. The performance of the proposed contour de- tector is compared with the performance of four other existing algorithms: the standard single-scale Canny edge detector [1]...

... the ANN. The ANN may be used to extract mathematical patterns and detect trends in the spectrogram and WVD that are too complex to be noticed by any other technique. The ANN has an ability to ... transfer functions allow the network to learn nonlinear and linear relationships between input and output vectors. The linear output layer lets the network produce values outside the ra...

... by means of a complete and open testbed. In a first stage, an integrated evaluation environment for VANET enabled us to analyze the network performance in detail in both per-hop and end -to- end manners, ... Show Log button. Users can also analyze the results by changing data density and see the trajectory of MR1 (and thus MNN1). Throughput results depending on the distance between MNN...
