This paper proposes the variable block-size transform and context-based entropy coding techniques for the enhancement layer of FGS (Fine Granularity Scalable) video coding. First,...
It is well known that JPEG2000 has a variety of advantages over its predecessor JPEG. JPEG2000 not only allows images to be coded with clearly better visual image quality, it also...
Block coders are among the most common compression tools available for still images and video sequences. Their low computational complexity along with their good performance make ...

Digital Watermarking is a labeling technique for digital images which embeds a code into the digital data so the data is marked. Watermarking techniques previously developed deal ...
This paper presents a novel face-assisted video coding scheme to enhance the visual quality of the face regions in video telephony applications. A skin-color based face detection ...
