General-purpose no-reference image quality assessment approaches still lag the advances in full-reference methods. Most no-reference methods are either distortion specific (i.e. t...

In this paper we present a DCT domain watermarking approach for H.264/AVC video coding standard. This scheme is resilient to compressed-domain temporal adaptation. A cryptographic...
A new down-conversion scheme in the DCT domain is presented, which can be used in decoders of DCT-compressed images and videos. The down-conversion in the transform domain general...
In this paper, we propose a novel feature extraction method for face recognition. This method is based on Discrete Cosine Transform (DCT), Energy Probability (EP), and Linear Disc...

To improve video quality and coding efficiency, H.264/AVC [1] has adopted several newer coding tools such as a 4?4 integer DCT and a method for calculating half pixels than the pre...
For the conventional downscaling video transcoder. the video server would be to first decompress the video, perform the downscaling operation in the pixel domain. and then recompr...
