One of the methods to improve image quality, which consists in increasing the resolution of image details by contrast enhancement, is to hyperbolize the image histogram. Herewith this increase in local contrast is carried out indirectly. It is due to

A new fuzzy logic and logarithmic transformation method for enhancing of low contrast color images is proposed. The input RGB image is converted into HSV (Hue, Saturation, Value) color space to preserve the chromatic information contained in the orig
