An image quality assessment method related with luminance details
Qiwei Hao · Journal of Hefei University of Technology · 2007
As the image quality depends on the individual subjective visual standard,the video quality analyzing methods based on the human visual system(HVS) model have become an active research field.Based on the idea of JND and the method of building the orthogonal transformation bank,the image is divided into different frequency bands,and the corresponding visual thresholds of luminance details in these bands are acquired.Then the damage factors of luminance details are obtained and a visual quality assessment method related with luminance details is constructed.Experiments are carried out,and the luminance detail optical thresholds of familiar orthogonal transformations fit well with subjective visual feelings,which proves the feasibility of the presented method.
