Abstract

The H.264/AVC is the newest and present standard for video coding. The H.264 standard is developed from the same mixed composition as of before standards, but contains several new coding techniques that increase the efficiency and quality of the video compression. H.264 video coding standard specifies different methods of approaches for video compression, which are termed as profiles, aiming particular applications that are required. In this paper, we proposed a 4×4 novel Integer transform, which is derived from the basic 4×4 DCT kernel by applying signum function to the float DCT kernel. The proposed transform is applied to the base line profile of H. 264 for evaluation of the compressed video quality. We have considered Mean Structural Similarity (MSSIM) metric for evaluation. Extensive simulation conducted on various types of videos show that the proposed transforms outperform the H.264 by a wide margin. Further, the proposed 4×4 IDCT requires 25% less computation than H.264 standard and 45% less computation than Int. discrete Tchebichef transform (IDTT).
