An efficient frequency domain intra prediction for H.264/AVC

This paper presents an efficient intra prediction implementation for H.264/AVC in the frequency domain. Intra prediction in the frequency domain is vital for transform domain heterogeneous video transcoding in wireless and mobile networks. A limited computation capabilities constraint constitutes a burden over such networks. New distributed intra prediction arithmetic is proposed with only addition and shift operations for transform domain intra prediction modes computations. Compared to previous attempts the proposed method reduces the computations extensively by eliminating the expensive matrix multiplications and omits the need for excessive memory storage.
