Currently, many people take pictures using digital instruments. However, the resulting images are sometimes not of good quality. To effectively communicate the information contained in the images, a method must be used to enhance image quality. To make an image sharper than the original, the Contrast Stretching technique increases or decreases the contrast (lighting). To produce better images, a technique is used to calculate intensity values and distribute the pixels evenly. This research was conducted to improve image quality using the same technique, but with a different input image, specifically RGB (color image), and the comparison method used was Contrast Stretching. The metrics used in this study are Mean Squared Error (MSE) and Peak Signal-to-Noise Ratio (PSNR). The software used is MATLAB R2015a.
