Abstract
Official abstract text for this publication.
The present invention discloses a method for establishing evaluation standard parameters 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 to tristimulus values of all pictures; respectively applying convolution to the frequency distribution function corresponding to each primary color with a contrast sensitivity function of human eye; respectively normalizing to each of the convolution functions; and selecting the evaluation parameters of the three primary colors of the standard picture as the evaluation standard parameters. The present invention can obtain more objective and systemic evaluation standard parameters.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for establishing evaluation standard parameters, the evaluation standard parameters 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 picture…
