Blur Analysis and Removal in Underwater Images using Optical Priors

To study and design under water imaging system in this paper we will use CODE V optical simulator. The effect of underwater turbidity will be studied with the help of optical parameter such as Point Spread Function (PSF). Point spread function (PSF) option computes the characteristics of the images of point objects including the effects of diffraction. It is used when the structure of polychromatic images are aberrated and to analyze it when it is out of focus. These test parameters will be then used for the design and implementation of restoration filter that will remove under water distortion completely. The prior estimated parameters will be used in a Bayesian Restoration Filter using least square approach. Experimental results show how the proposed algorithm is better than existing methods both qualitatively and quantitatively. Keywords— Turbidity, Code V, PSF, Image restoration.
