JPEG-LS

Features of construction of devices for compression of lossless images are considered. The study of the features of the construction allows you to fully understand the principles of these devices and the methods of compression, which underlie their work. JPEG-LS method and CCSDS121.0-B-2 standard are chosen as ways of compression of lossless images. The implementation of these methods with different types of architectures on modern FPGAs is considered. A comparison of the results of the implemented nodes on the FPGA.

The features of devices for monochrome images lossless compression by JPEG-LS method in modern element base are discussed. Capabilities of Vivado package (Xilinx) for JPEG-LS algorithm C to suitable for implementation in FPGAs VHDL-descriptions transformation were tested and described. C language structures, which can not be processed by specified means and possible circumvention of such structures were defined.
