Báo cáo hóa học: " Research Article Steganography in 3D Geometries and Images by Adjacent Bin Mapping" ppt

... 2009 Recommended by Andreas Westfeld A steganographic method called adjacent bin mapping (ABM) is presented. Firstly, it is applied to 3D geometries by mapping the coordinates within two adjacent bins for ... when the bin size is tiny because there are few coordinates in the same bin. When there is no coordinate in one bin, no data can be embedded despite how many coordi...

... recognition to 3D by combining multiple single views. We take a systematic extension to build 3D information us- ing multiviews and perform optimization of the descriptor in respect of the number and the ... holistic features (without using subregion features) for each view. And im- ages of nearby views are also included in the training of cer- tain view (i.e., in obtaining...
