| Abstract: |
| This work aimed to solve the problem that different color temperatures of LCD monitor have a relatively great impact on the human eye color perception. A image enhancement method of perception of the same color under different color temperatures of LCD Monitor was proposed using advantages of the BP neural network nonlinear conversion and color adaptive transformation. The average color difference of the 100 colors was 1.0441, the minimum color difference was 0.3034, and the maximum color difference was 1.9757, which was consistent with the requirements of visual consistency. The image subjective Z score was 0.61844 after image enhancement using this method. This method could well solve the problem of image display on the LCD monitor under different color temperatures, to achieve the purpose of image enhancement. |
