2. My optimized tone mapping algorithm

Natural sceneries often have a high dynamic range (HDR) ratio that exceeds 100,000:1. Although good-performance HDR sensors can capture HDR images, most display devices are LDR which is about 8-bit. In this mismatch, the details of the HDR image will lost, such as can be seen in over-exposed or under-exposed scenes. To solve this challenge, tone mapping algorithms have been used to adapt the captured HDR image to the LDR display devices while still maintaining image details.

In last year, I started developing and optimizing tone mapping algorithm. The following images are comparison between the original images and tone mapped images after my optimized algorithm. Because our work have not been published, the algorithm in details are not shown. Once it published, I will update my blog about the algorithm in details.
