Distribution prediction for image compression: An experimental re-compressor for JPEG images
Maxim Koroteev, Yaroslav Borisov, Pavel Frolov
AbstractWe propose a new scheme to re-compress JPEG images in a lossless way. Using a JPEG image as an input the algorithm partially decodes the signal to obtain quantized DCT coefficients and then re-compress them in a more effective way.
