Display gamut mapping based on image quality assessment
To solve the image color reproduction problems for display devices
a gamut mapping algorithm based on image quality assessment and image segmentation-fusion strategy was proposed.Firstly
different sorts of gamut mapping algorithms were analyzed in detail and 4 algorithms were chosen as basic algorithms. And then
a gamut mapping image quality assessment method was proposed
and SLIC superpixel algorithm was used to carry out the source image segmentation. Gamut mapping was applied to the source image with the basic algorithms
and similarity was calculated within each image segment between mapped images and source image. According to the calculated similarities
each mapped image was chosen and comprehensively processed
and fused to the final image. Finally
with LED display panel and LCD display as an example
a subjective evaluation experiment was made to the proposed algorithm and other basic gamut mapping algorithms. Experiment result shows that the proposed algorithm is apparently better than other ones on keeping image color fidelity
and yet the calculation speed still needs to be improved.
