Image dehazing by artificial multiple-exposure image fusion.

•A new Image Dehazing method based on artificially under-exposing the input hazy image to different degrees and performing a multi-scale fusion on the resulting set of images is presented.•The method can decrease the amount of haze effectively with a minimal amount of parameters to adjust by the user.•The method competes well with other state-of-the-art image dehazing techniques, often overcoming them.•The proposed technique is robust and fast - code to reproduce all the examples in the paper is released.
