The main purpose of this paper is to review the essential techniques in the field of image processing and enhancement. The image enhancement is an important and challenging research area. The primary objective of image enhancement is to improve the visual appearance of the original image to produce an enhanced image which is more suitable for specific applications. Digital image enhancement techniques offer a multitude of adoptions for improving the visual quality of images. There are many types of pictures, such as medical images, satellite images and aerial photographs and even images and real-life suffering from the weakness of contrast and noise. Therefore, it is necessary to improve applications for increasing the image quality that could help to enhance contrast and remove the noise from the original image. Therefore, this paper aims to provide an overview of fundamental concepts, algorithms, processing methods used for image enhancement. A case study is deploying a salt and pepper noise on cameraman and spin images is presented and addressed using MATLAB software.
