A new bit estimation scheme for H.264 rate control

Abstract

~ Rate control is a critical isstre in ff.264 video coding standard. This paper aims at improving video qualit?; at .scene changes and high motions hv acccrrately estimating the target hits in H.264 rate control. We define a neu, measure. nameLv motion comple.rit?;, to represent the amount oJ' motion content.s between two consecutive frames. Mulion complexit?; i s closely correlated to the bits !ha/ have been allocated to the p?evious/v encoded frames. Based on motion comple.riv. we propose a new and simple scheme to estimate the target bits in rate control. Experimental results show that our bit estimation scheme can effectively reduce /he sharp drops of peak signal-to-noi.se ratio (PSNR) ai scene changes and high motions as compared with the H.264 proposal'. alphabetical order, separated by commas.
