In this paper, we propose novel algorithmic models based on feature transformation in cross-modal subspace and their multimodal fusion for different types of residue features extracted from several intra-frame and inter frame pixel sub-blocks in video sequences for detecting digital video tampering or forgery. An evaluation of proposed residue features - the noise residue features and the quantization...
A step-variable shot detection algorithm of soccer video based on DC image is presented in this paper. The proposed method uses the DC image as original data and the grass ratio as feature parameter in soccer field. This algorithm only needs partly decompression from the encode bit-stream and doesnpsilat need all the histogram comparison between adjacent frames, so it can reduce the computational...
