摘要
提出了一种基于人脸区域的图像质量客观评价模型算法,该算法将整个图像区域划分为感兴趣区域(人脸区域)和不感兴趣区域,对这两个区域内的图像损伤,在计算中分别赋予不同的权重,以体现人眼的感知兴趣。实验证明通过该模型算法得到的客观评价结果与人眼的主观感觉具有更好的一致性。
The proposed algorithm divides the image area into two parts: regions of interest (ROI) and other regions. The ROI here is the human face region. The impairment of two regions are given different weight in calculation, thus the human visual interests are represented. The experimental results show that the objective evaluation obtained by this algorithm has better correlation with the subjective feeling of human eyes.
