Lossless Compression of Already Compressed Textures
Texture compression helps rendering by reducing the footprint in graphics memory, thus allowing for more textures, and by lowering the number of memory accesses between the graphi...

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...

Compression color space estimation of JPEG images using lattice basis reduction
Given a color image that was quantized in some hidden color space (termed compression color space) during previous JPEG compression, we aim to estimate this unknown compression co...

Lossless Image Compression and Selective Encryption using a Discrete Radon Transform
In this paper we propose a new joint encryption and lossless compression technique designed for large images 1 . The proposed technique takes advantage of the Mojette transform pr...

Evaluation of Lossless Compression Methods for Gray Scale Document Images
In this paper, a comparative study of lossless compression algorithms is presented. The following algorithms are considered: UNIX compress, gzip, LZW, CCITT Group 3 and Group 4, J...
