Abstract

Given a set of target bits, video rate control algorithms that use Lagrange multipliers have been generally known as an optimal solution for maximizing the picture quality in uniform spatial domain. Even if the SNR (signal-to-noise) of a picture is maximized by the rate control scheme, the visual quality can be enhanced using a suitable algorithm for the human visual system. In this paper, we establish a new optimal rate control algorithm for maximizing the SNRC (signal-to-noise ration in curvilinear coordinates) using Lagrange multiplier. In addition, a target bit allocation technique for foveated video is introduced for simplified rate control over MPEG/H.263 video standards.
