Research on color correction technology of cultural heritage documentary vid-eos for user experience optimization
摘要
Abstract
Scene shooting for cultural heritage documentary videos usually has complex non-uniformly distributed illumina-tion.The spatial heterogeneity of this illumination makes the color areas in the image differ greatly,and the color correction is difficult and the reduction degree is low,which affects the user experience.Therefore,this study proposes a color correc-tion technology for user experience optimization.Firstly,according to the original contrast of the video image and the sec-ond-order color matrix,the local measurement value of contrast is calculated,and the color distribution characteristics are obtained by combining the single-channel response edge function to enhance the optimized picture.Then,the super-pixel segmentation method is used to segment the image,while combining the color deviation correction coefficients of the pic-ture with the generalization of super-pixels to eliminate the color deviation.Finally,the darkened edges are restored,the motion residual is determined,and the color correction is completed by combining the sampling variance method.Experi-ments show that this method is effective in improving contrast and clarity,optimizing shadows,correcting color deviation,etc.The similarity between the corrected image and the histogram of the reference image is more than 0.80,and the aver-age speed of processing the video images can be increased to 4 seconds per piece,which can conclude that this method has a high degree of color reproduction of cultural heritage documentary videos,effectively optimizing the user experience with an excellent processing performance.关键词
