摘　　要：HDR图像经过压缩与分层处理后会改变它的亮度和纹理信息,使得HDR图像与最初图像的亮度分布比例出现偏差。为了保证图像处理前后的显示效果相近,需要对图像的颜色进行恢复处理。研究了在传统的基于图像色貌模型颜色恢复方法的基础上进行改进,通过引入最新的CIE CAM16色貌模型对图像进行色适应转换,有效地改善了HDR图像映射处理过程中的色貌偏移问题。In order to ensure that the display effects before and after image processing were similar,it was necessary to restore the color of the image. The traditional color restoration method was improved based on image color appearance model. By introducing the latest CIE CAM16 color appearance model to perform color adaptation conversion on images,the problem of color appearance shift in the process of HDR image mapping was effectively improved.
