Abstract

This paper presents an enhanced rate control scheme for H.264 using motion detection and motion analysis. PSNR based measure is used for determining motion complexity and detecting scene changes. Motion Vectors and Rate Distortion measures are further used to classify regions with motion inside a frame and Macro-blocks are then grouped into slices using the Flexible Macro-block Ordering feature of H.264. We present a filtered slice grouping technique to maintain a stable region of motion. The proposed method provides smoother quality videos with better average PSNR. The bit rates are within bound and fewer frames are skipped in sequences with scene changes at low bit rates.
