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. To appear in IEEE Trans. on Image Processing The author is with Xerox Corporation E-mail:
