基于面部定位的头肩像视觉质量评价方法

A visual quality assessment measure based on facial localization of the headandshoulders scene

从人类的视觉生理和心理特性出发，研究图像（特别是头肩像）的视觉感受特性．结合知识基的面部定位策略，提出一种能够正确反映头肩像视觉感受的质量评价方法，并用来指导低比特率序列图像编码量化器的设计．

By inspecting physiology and psychology on human vision, we attempt to study the perceptual characteristics of the image (especially for the headandshoulders scene). Based on the human face location technique, a novel Quality Assessment Measure (QAM) is given which can correctly reflect the subjective visual reaction of the headandshoulders scene, and it can be incorporated to design the quantizer used in low bit rate sequence image coding.
