To improve the clarity and visual quality of the low light video images and also to identify hidden details in the images and also to solve the problem of information retrieval from the image caused by color distortion and low saturation are performing image enhancement with classic Retinex algorithm. In the Current scenarios Digital image are been limited in clarity and this is due to poor visibility conditions which may including bad weather like fog, smoke, rain and at dawn. These unique conditions limit the range and effects of imaging it can’t be enhanced further. we useRetinex algorithm here which is most popular and that can be implemented to image enhancement. The basic idea of Retinex algorithm is to exactly split or extract illumination from the reflectance for a given digital image. I have made a study and analyzed how to implemented Retinex algorithm based on color exactly decollation and color constancy with some more additional technique, These method associates in removing noise in the Image.Retinex algorithm has been utilized in cases of severe aerial photograph as well as image blurring with a noticeable results.
