WebThe Salt & Pepper noise is generally caused by defect of Noise encountered into RGB color image caused by images camera sensor, software failure, or hardware failure in image captured sensing devices and transmitted communication capturing or transmission. Due to this situation, Salt & Pepper noises reduce the visual quality of an image. WebSalt & Pepper noise value may be either minimum (0) or maximum (255). The typical intensity value for pepper noise is close to 0 and for salt noise is close to 255. Furthermore, the unaffected pixels remain unchanged. (1) 1.2 Median filtering Is a nonlinear method widely used to remove ‘salt and pepper’ type noise.
