Non-Uniform Illumination Underwater Image Restoration via Illumination Channel Sparsity Prior

Underwater image quality is seriously degraded due to the insufficient light in water. Although artificial illumination can assist imaging, it often brings non-uniform illumination phenomenon. To this end, we develop an illumination channel sparsity prior (ICSP) guided variational framework for non-...
