摘要
This paper proposes a novel image restoration algorithm to eliminate light attenuation in underwater environments. The proposed algo-rithm employs the distance-dependent formation to model the degradation process where light travels in underwater. We use a homomor-phic 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.
