P‐3.11: An Improved Compression Method of HDR Image Dynamic Range

People have higher and higher requirements for image quality at present. High dynamic range (HDR) images are widely used in film, television, medical and other fields, and have become an important research direction in the field of image processing. Aiming at the problem of information loss in the dark and bright areas of the image caused by the existing dynamic range compression method, this paper improves the traditional logarithmic domain dynamic range compression method, and realizes the overall image adjustment according to the adaptability of the human eye to the brightness. While the dynamic range is compressed, more information about the darker and brighter areas is preserved.
