| description | The invention belongs to the technical field of image and video processing, and particularly discloses a high dynamic range image compression method based on a mixed tone mapping algorithm. According to the high dynamic range image compression method, the problem about image distorsion when a high dynamic image displays on general display equipment is mainly solved. The high dynamic range image compression method comprises the following steps: firstly, using global linear compression based on image types to save the integral effect of the image; secondly, further enhancing the naturalness of the image by using an adaptive avoiding and value burning technology; finally, improving the visibility of image detailed information by using a local tone mapping algorithm based on a dual-side filter. According to the high dynamic range image compression method disclosed by the invention, a natural distinct low dynamic image result can be obtained; the high dynamic range image compression method can be widely applied to relevant fields of image and video processing. |
