Abstract :
This paper presents an efficient JPEG decoding and scaling method which reduces both of memory requirement and processing time. The proposed method overlaps decoding, horizontal scaling and vertical scaling, which results in average 92.6% reduction of memory space and average 82.8% reduction of processing time for test cases.
