A Novel Underwater Image Restoration Algorithm
Yongxin Wang · International Journal of Performability Engineering · 2018
This paper proposes a novel image restoration algorithm to eliminate light attenuation in underwater environments.The proposed algorithm employs the distance-dependent formation to model the degradation process where light travels in underwater.We use a homomorphic filter to get rid of the non-linear in the distance-dependent model.The restoration underwater image is then obtained by solving a Poisson equation that is derived based on the similar distance of neighbourhood pixels.The experiments show that the restoration image reveals improved contrast and clear details.
