Improved Chen-Smith image coder
An image compression system based on transform coding and zonal sampling is presented. It is based on the wellknown Chen-Smith coder, but with an improved technique for transform ...

Reduction of Interband Correlation for Landsat Image Compression
We present a lossless compressor for multispectral images that exploits interband correlations. Each band is divided into blocks, to which a wavelet transform is applied. The wave...

Improved POCS-Based De-blocking Algorithm for Block-Transform Compressed Images
This paper presents a postprocessing technique based on the theory of projections onto convex sets (POCS) to reduce the blocking artifacts in low bit rate BDCT-coded images. In the...

Lossless Compression of Color-Quantized Images Using Block-Based Palette Reordering
Abstract. It is well-known that the lossless compression of color-indexed images can be improved if a suitable reordering of the palette is performed before encoding the images. In...

Boosting Saliency in Color Image Features
The aim of salient point detection is to find distinctive events in images. Salient features are generally determined from the local differential structure of images. They focus o...
