中文摘要：文中以敦煌莫高窟为应用背景，介绍了基于类比的计算机辅助古代壁画色彩恢复方法．将色彩保持相对完好的壁画图像以及描述壁画属性的特征参数作为壁画色彩恢复的类比源存入数据库，根据决定和影响壁画色彩的不同因素，特征参数分为３ 个层次，以便于图像数据库的类比检索．为了在处理图像过程中与人的视觉保持一致，除ＲＧＢ颜色空间外，又选择了ＳＨＩ颜色空间．结合图像色彩区域提取、基于直方图的色彩转换等技术实现了壁画图像的色彩复原

英文摘要：A new computer\|aided analogy approach for color restoration of ancient mural is proposed in this paper. The mural images whose colors are relatively intact are stored, along with their feature parameters used to describe the murals, into the database as the analogy source for color restoration of faded murals. The feature parameters are classified into three levels according to different factors that determine and affect the color of mural. The database can be retrieved from one or more than one level. In order to achieve a uniform perception with human vision, SHI color space is chosen. Several techniques for color image processing are used to process the mural image. These include color object extraction based on interactive region growing and color transformation based on color histogram.
