A Bit Allocation Scheme Based on Visual Properties

Presents a bit allocation scheme based on visual properties. Through the analysis of visual properties, corresponding visual importance estimates of segmented regions are made. As a result, the important regions of interest (ROI) will be ascertained and allocated in order to the quantified ROI values which reflect the importance of each region. Experimental results show that the reconstructed image quality of the video coder produced by the algorithm accord with human subjective conclusion well, and the algorithm have desirable application value and low computation cost.
