Modified Color Brightness Preserving Bi-histogram Equalization with Variable Enhancement Degree for Restoration of Skin Color

Histogram equalization (HE) is a popular techniques used for digital image enhancement. In case of Color image processing, brightness of the color is to be preserved. In this paper, author has taken an attempt to restore the skin color in the color image. Existing method for enhancement have been verified and implemented for restoration. The control parameter has also been formulated. According to the control parameter, the existing BBHEwVED method has been modified and applied for skin color restoration. After comparison of all the method, it has been found that method 5 shows excellent results. Our proposed method is able to control the enhancement degree, where the mean of image is preserved, hence all kinds of images are enhanced adequately. We mainly consider the natural color images like human face to restore the original skin color. Thus, we adjust the parameter of BBHEwVED, in order to restore the skin color of human face.
