A context adaptation model for the compression of images with a reduced number of colors
Recently, Chen et al. proposed a method for compressing color-quantized images that is based on a binary tree representation of colors and on context-based arithmetic coding with ...

Clustering Context Properties of Wavelet Coefficients in Automatic Modelling and Image Coding
An algorithm for automatic modelling of wavelet coefficients from context properties is presented. The algorithm is used to implement an image coder, in order to demonstrate its i...

Object-Based Video Coding Using Pixel State Analysis
In archiving video for surveillance, frame-based coding has been used and it makes storage size large because the whole image is stored even if there is no object in the image. On...

On the non-optimality of four color coding of image partitions
Recent interest in region based image coding has given rise to graph coloring based partition encoding methods. These methods are based on the four color theorem for planar graphs...

A differential motion estimation method for image interpolation in distributed video coding
Motion estimation methods based on differential techniques proved to be very useful in the context of video analysis, but have a limited employment in classical video compression ...
