| Summary: | 碩士 === 大同大學 === 通訊工程研究所 === 102 === Most of image quality assessment (IQA) methods only concern about gray image, and don’t make use of image color information sufficiently at present. A method for reduced-reference color image quality assessment is proposed, which based on structural features and efficiently uses the color information. The structure information inherent in three-dimensional (3D) color signals can be obtained from K-means clustering classification. The final image quality assessment is defined by the weighted combination of three components. To verify the validity of the proposed metric is evaluated against a large amount of test images in LIVE database and compared with that of the famous Structural Similarity Measure for Color Image (CMSSIM). The experiments show that the proposed objective method has a good coincidence with the subjective perception, and can reflect the image quality effectively.
