The research work is focusing on lossless compression during image processing. Several integrated approaches have been used in this research to perform image compression. Image Compression is reducing the size of data where digital graphical content compression eliminates data images. Several algorithms &...
The image compression part of the method proposed here produces compression ratios within 95% of JPEG (from Hewlett Packard) compression ratios. It also provides a reliable information hiding scheme able to hide in an invisible way messages of 12.5% of the size of the original image. Further ...

The JPEG-LS-E core implements a highly-efficient, low-power, lossless and near-lossless image compression engine that is compliant to the JPEG-LS, ISO/IEC 14495-1 standard. Based on LOCO-I (LOw COmplexity LOssless COmpression for Images), the JPEG-LS algorithm leads in numerically lossless...
The decoder core can decompress greyscale, truecolor, and palette-based PNG images with 8 and 16 bits per color. The core supports alpha channel transparency¬ and all the filters and DEFLATE compression options specified by the PNG standard. The core does not currently support interlaced mode ...
