An implementation of the ICCP '16 paper "Blind Dehazing Using Internal Patch Recurrence".

Blind Dehazing Algorithms

This is an implementation of single image blind dehazing algorithms. We attempt to implement two papers, the ICCP '16 paper "Blind dehazing using internal patch recurrence", by Yuval Bahat & Michal Irani, and the CVPR '09 paper "Single Image Haze Removal Using Dark Channel Prior" by Kaiming He, Jian Sun, and Xiaoou Tang.

The implementation of "Single Image Haze Removal Using Dark Channel Prior" is complete. Run it using ./start_dark_channel.sh. Use the --help flag for a detailed list of arguments. Hyperparameters can be adjusted in dark_prior/config/constants.yml.

The implementation of "Blind dehazing using internal patch recurrence" is in progress.
