Lossless image compression techniques typically consider images to be a sequence of pixels in row major order. The processing of each pixel consists of two separate operations. Th...

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...

Frequently, it is observed that the sequence of indexes generated by a vector quantizer (VQ) contains a high degree of correlation, and, therefore, can be further compressed using ...

The efficiency of compressing color-quantized images using general purpose lossless image coding methods depends on the degree of smoothness of the index images. A wellknown and v...

Most existing lossless image compression schemes operate on grey-scale images. However, in the case of colour images, higher compression ratios can be achieved by exploiting inter...
