Motion wavelet difference reduction (MWDR) video codec

In this paper, a new fast video codec using Wavelet Difference Reduction (WDR) algorithm is presented. This proposed video codec is inspired by the concept of motion JPEG; namely, we adapted the efficient WDR still image compression algorithm into a video compression algorithm without the motion estimation step. This approach significantly reduces the processing time for motion vector search and motion compensation procedures. In addition, we employ block-based WDR algorithm which significantly reduces the memory requirement while comparing to other wavelet based compression algorithm.
