  annote = {This report describes an approach to speed up recoding of baseline JPEG images. Recoding is commonly done in proxy systems in order to increase the degree of compression before transmitting data over a slow link such as a mobile phone connection. The described approach performs the recoding in the intermediate DCT coefficient format instead of decoding the image to a pixel representation before applying the increased compression. Measurements show that other recoders require between 50 and 300% more time to recode than the proposed efficient recoder. For typical Web images and an efficient but pixel-based recoder the additional time required is approximately 100% more than the time required for the proposed recoder. Memory requirements were also measured, and the results show that the suggested recoder is memory efficient for typical images.},
