  • Improving the efficiency of the compression of computer graphics using RLE algorithm

    At the speed of the web resource greatly affect loadable external objects. The most common of them - the image. In this connection it becomes actual size reduction loadable computer graphics (images) to reduce the overall size of the web page. Among the least popular compression algorithms algorithms for lossless coding, because of their low efficiency. However, for a certain class of images through the use of its specific features, it is possible to obtain a much higher compression ratio in lossless coding. The authors proposed a modification of the RLE algorithm, which allows to increase the compression ratio of the images with large areas of solid color.
