The pictures taken in awful climatic conditions will adversely influence the picture quality. Fog and haze degrades the picture standard, air-light lessens whiteness of the image and attenuation lessens its contrast. This paper provides colour attenuation prior for haze removal of the image. The main aim is to solve the problem of reduced visibility by excellent image processing strategy and the purpose is to improve the quality of images that lack the shading, complication and depth when perceived by the human eye. By creating a straight model for display the scene extent of the hazy image, we can easily determine the transmission and resume the scene radiance via the atmospheric scattering model. © 2018 IEEE.
