Underwater image colour constancy based on deep sparse nonnegative matrix factorization

What is it about?

Underwater image enhancement is a difficult problem. It used specific hardware or technique to solve. We firstly use the Deep NMF to estimate the illumination and apply to the underwater image. The experiment results show that our method obtained a comparable visual effect and image quality assessment.

Why is it important?

We use a single underwater image to enhance degraded underwater image. Furthermore, the proposed method is efficient and simple to implement.
