In this paper we propose a novel feature extracting method based on spatiotemporal slice analyzing. To date, video features are focused on the character of every single video frame. With our method, the video content is no longer represented with every single frame. The temporal variation of visual information is taken as an important feature of video in our method. We examined this kind of feature...
In this paper, a fast transform method is proposed to convert MPEG-2 8-tap discrete cosine transform (DCT) coefficients to H.264/AVC 4-tap integer transform coefficients directly in the transform domain. The proposed transform method saves 16 operations for each 8times8 DCT block by utilizing a novel transform kernel matrix and a fast computing method for multiplication of this new matrix. The simulation...
Converting MPEG-2 8-tap discrete cosine transform (DCT) coefficients to H.264/AVC 4-tap integer transform (IT) coefficients is one of the indispensable operations for transcoding MPEG-2 to H.264 in the transform domain. Motion information in the input MPEG-2 sequence should be reused as much as possible to speed up the transcoding process. Motivated by this, we first exploits the distribution information...
