| Abstract | ||
| The objects in the underwater images are not clearly visible due to low contrast and scattering of light and the large noise present in the environment which leads to lose its original color and details. The Retinex is an image enhancement algorithm that improves the brightness, contrast and sharpness of an image. In this study, we proposed a new image enhancement algorithm dependent on the Modified Multi Scale Retinex Algorithm with Color Restoration (MMSRCR). This technique is using the lightness component in YIQ color space that is transformed by the Sigmoid Function and then it is applied in the traditional multi scale retinex algorithm MSRCR image after reveres transformation. Relationship between the mean and the average of standard deviation for image has been done to examine the efficiency of the method.All algorithms has implemented using program (Matlab). | ||
