Abstract
We present techniques that allow the processing of an image in the “JPEG-compressed” domain. The goal is to reduce memory requirements while increasing the speed by avoiding decompression and space domain operations. An effort is made to implement the minimum number of JPEG basic operations. Techniques are presented for scaling, previewing, rotating, mirroring, cropping, recompressing, and segmenting JPEG-compressed data
