摘要 由于处理位数的限制,导致在常规设备上显示HDR图像必须对其进行阶调压缩。将图像局部环境亮度因子应用到了HDR图像阶调压缩中,提出了基于局部环境亮度因子的HDR图像阶调压缩的具体算法流程,并采用动态范围独立的图像评价模型,对新算法性能进行了视觉定量评价。评价结果证明,新算法的压缩效果较为明显,也有效地降低了算法的复杂性。 Tone compression of HDR images is necessary for displaying HDR images on conventional device because of treatment capability restrictions.The luminance factor of local environment was applied in tone compression of HDR images.The specific algorithm workflow of the HDR image tone compression based on luminance factor of local environment was put forward.Quantified evaluation of the performance of the algorithm carried out with Dynamic Range Independent image quality model.The evaluation results showed that the new algorithm can achieve a good effect of tone compression for HDR images,and greatly reduce algorithm complexity.
