Efficient Inter-Band Prediction and Wavelet Based Compression for Hyperspectral Imagery: A Distributed Source Coding Approach
Hyperspectral images have correlation at the level of pixels; moreover, images from neighboring frequency bands are also closely correlated. In this paper, we propose to use distr...

Blocking Artefact Free Video Coding Based on a Bilinear Forward Image Warping Model
In this paper a new very low bit rate video coding scheme is presented. It is based on a forward motion estimation technique using an image warping model, thus delivering the basi...

Down-scaling interlace video from H.264/AVC intra-coded bit stream
In this paper, we develop a method for generating thumbnail images from the interlaced H.264/AVC coded bit streams. We devise a method exploiting both the spatial and transform do...
