The algorithm for determining the threshold values of noise depending on the influence of various factors (illumination, pattern video sensor, temperature and others) which allows adaptively determine the degree of noise for each image has been developed. Adaptive iterative method for reducing the bit of image data, which allows the number of bits adaptively choose to encode each color channel, has been developed to reduce the amount of data. New integer sine transformation of order 4 and 8 with fast algorithms that are 4.2 times greater performance compared to prior art and provide improved efficiency encoding PSNR characteristics have been developed. These sine transformation are especially effective for images with low correlation.
