The Underwater pictures normally experience the ill effects of non-uniform lighting, low differentiation, obscure and decreased hues. Shading disperse is brought about by murkiness impacts happening when light reflected from items is consumed or dissipated on various occasions by particles in the water. This thus brings down the perceivability and complexity of the picture. In view of explicit transmission properties of light in the water, Underwater picture additionally experiences restricted range, non uniform lighting, low complexity, shading lessened, and significant haze In this thesis a picture based preprocessing method has been proposed to upgrade the nature of the Underwater pictures. The goals of this methodology is to Firstly, apply mix of Preprocessing channels in particular Noise Removal Filter, Median channel and Wiener channel to the corrupted Underwater pictures and lessens Underwater irritations and furthermore improves picture quality. Furthermore, the immersion and force extending of picture is utilized to build the genuine nature and take care of the issue of lighting. It is made out of a few progressive free preparing advances which right non uniform brightening, smother commotion, upgrade differentiate, modify hues and jelly Edge Component. At long last, Performance of Each channel is analyzed on certain parameters like PSNR and MSE
