Processing JPEG-Compressed Images

As JPEG has become an international standard for image compression, we present techniques that allow the processing of an image in the JPEG-compressed" domain. The goal is to reduce memory requirements while increasing speed by avoiding decompression and space domain operations. In each case, an e ort 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. While most of the results apply to any image we focus on scanned documents as our primary image source.
