Enhancement of LLLIs with improved BCP and matrix completion
Yang, Jie
AbstractThe problem of enhancement of low light level images (LLLIs) with the characteristics of extremely low brightness and low contrast is addressed. A coarse-to-fine framework to settle the problem is proposed. First, a point-wise linear relationship is constructed between an LLLI and its enhancement result, and a prior named bright channel prior (BCP) is introduced to guide the enhancement process. The BCP to avoid over enhancement is improved, and the idea of matrix completion to remove the outlier noises in the enhanced image is used. Experimental results on real images demonstrate that the method is effective for the enhancement of LLLIs.
