Abstract
Official abstract text for this publication.
The present invention discloses a method for establishing an evaluation standard parameter and method for evaluating the quality of a display image, wherein, the method comprises: taking pictures to a group of test images having different color shift severity degrees to obtain a sample picture group; selecting a standard picture by human eye; applying the Fourier transform for the brightness of the pictures of the sample picture group; applying convolution to the frequency distribution function and a contrast sensitivity function of human eye in the frequency domain; normalizing to the convolution function to obtain an evaluation parameter; selecting the evaluation parameter of the standard picture from the evaluation parameters of all the pictures of the sample picture group as an evaluation standard parameter. The present invention can obtain more objective and systemic evaluation standard parameter.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for establishing an evaluation standard parameter, the evaluation standard parameter for evaluating the quality of a display image, the quality of the image being inversely proportional to the severity degree of the color shift phenomenon of the image, the method comprising: taking pictures to a group of test images having different color shift severity degrees to obtain a sample picture group, and selecting a standard picture from the sample pictur…
