Application of Multiscale Retinex in JianDu Image Enhancement
多尺度Retinex算法在简牍图像增强中的应用

Enhancement of the JianDu Image is a key procedure in character reconstruction and text extraction.We made the JianDu relics from Changsha Jiandu museum as a model and taken the JianDu images as our research objects.An enhancement algorithm of JianDu image based on multiscale Retinex was presented.Based on the theory of Retinex,the multi-scale Retinex(MSR) algorithm was employed to remove the luminance degradation of the JianDu image.The information of hidden area of the JianDu image was obviously enhanced....
