A Linear Color Correction Method for Compressed Images and Videos Kebin AN Jun SUN Lei ZHOU Publication IEICE TRANSACTIONS on Information and Systems Vol.E89-D No.10 pp.2686-2689 Publication Date: 2006/10/01 Online ISSN: 1745-1361 DOI: 10.1093/ietisy/e89-d.10.2686 Print ISSN: 0916-8532 Type of Manuscript: LETTER Category: Image Processing and Video Processing Keyword: color correction, color space, MPEG-2, DCT, Full Text: PDF(314.1KB)>>
Summary: Color correction needs to be performed to improve the quality of image/video production. The typical methods realize the color correction mainly in the spatial domain of RGB color space. In this paper, a linear color correction method in JPEG/MPEG-2 compressed domain is proposed. The correction is realized in the DCT domain of YUV color space without full-frame decompression. Experimental results show that the visual quality of the corrected images/videos in the compressed domain is identical to the quality of the images/videos corrected in the uncompressed domain. | ||||||||||
