Final Project

Recovering HDR Radiance Map and Tone Mapping

Usage: Please download the test images first. The use the Choose Files button to select a set of multiple exposure images to perform HDR image reconstruction and tone mapping. After selecting the images, the source images will appear in the page, and you can hit Generate button to start.
