Abstract :
Scattering is an important aspect to be addressed in the field of underwater image processing. The phenomenon of scattering can be better understood by considering interaction of light ray and particle in the medium .Scattering is commonly approximated as a deterministic phenomenon. In the present work, we propose a probabilistic model based on light-particle interaction and provide a modified Point Spread Function (PSF). The PSF so obtained may be used to better explain a physical phenomenon (beam-particle interaction) in the underwater point source image.
