| 摘 要： | 为解决高动态图像的真实影像再现问题,提出了一种基于参数控制的混合色调映射方法.对图像进行全局预处理,保持整幅图像的亮度和对比度;采用参数控制的混合算子获取图像的局部对比度和细节;采用双边滤波解决色调映射过程中产生的光晕问题.仿真实验表明,该方法压缩了原始高动态图像的动态范围,保持了整体亮度,增强了局部细节而去除光晕效应影响,比现有的Sigmoid算法在各个参数上有显著提高.

| Abstract: | In this paper a hybrid tone mapping method was investigated to solve the problem of realistic image reproduction. Firstly, the image was preprocessed to keep the overall brightness and contrast. Then the local details and contrast information with parameter controlled hybrid operator were obtained. To solve halo artifacts, a bilateral filter was also presented for processing. Experiments show that the proposed algorithm is practical that effectively compresses the dynamic range, maintains the image details, removes the halo artifacts and improves significantly, in contrast to the sigmoid algorithm method. |
