摘  要： 针对原有中国画色彩修复系统识别色彩修复边缘能力不足的问题，基于图像处理技术设计新式的中国画色彩修复系统。在保留原有系统硬件的前提下，更换一个采集能力更强的图像采集卡，将其与USB端口和图像采集器相连接，增强系统的图像识别能力。在系统软件方面，此次设计利用图像处理技术，结合损失公式，识别待修复色彩区域的衔接边缘;建立色彩提取区域，计算色彩最优点的位权值，找出色彩提取位置，并按照原有绘画色彩叠加方式，将不同颜色合成;利用偏微分方程设置色彩修复系统的修复代码，实现对中国画色彩的修复。实验测试结果表明，与原有修复系统相比，所设计的色彩修复系统识别中国画色彩修复边缘的能力更强，修复后的中国画质量更高。由此可见，该色彩修复系统可应用于中国画的色彩修复。

Abstract： As the original color restoration system for the Chinese paintings does not have enough capability to recognize the edge of color restoration， a new color restoration system for Chinese paintings is designed on the basis of image processing technology. On the premise of retaining the original system hardware， the original image acquisition card is replaced by an image acquisition card with stronger acquisition ability， which connects USB port and image collector to enhance the image recognition ability of the system. In terms of system software， the image processing technology and loss formula are adopted in the system design to identify the join edge of the color area under restoration， establish the color extraction area， and calculate the optimal bit weight value of color to find out the color extraction position and compound different colors according to the original color superposition method. The restoration code of the color restoration system is set up with partial differential equation to realize the color restoration of the Chinese paintings. The experimental results show that， in comparison with the original restoration system， the designed color restoration system has a stronger ability to recognize the color restoration edges of the Chinese paintings， and the quality of the restored Chinese paintings is much higher. This shows the color restoration system can be applied to the color restoration of the Chinese paintings.

中國画作为一种历史悠久、传统优良的中华民族传统绘画，凝聚着大量的中华民族历史信息，体现了一代又一代人民的民族智慧以及每一时期的人物性格，同时也反映了历史发展趋势、国家的政权变革等社会发展情况，可见中国绘画不仅仅是对中华五千年民族精神的体现，还充分反映了国家的历史发展进程。但由于中国绘画出现的时间早、流传时间久远，导致原本色彩丰富、鲜明的中国绘画出现了局部褪色、边缘褪色以及总体晕染的情况[1]。……
