Abstract

Image Enhancement is one of the first steps in Image processing. In this technique, the original image is processed so that the resultant image is more suitable than the original for specific applications i. e. the image is enhanced. Image enhancement is a purely subjective processing technique. An image enhancement technique used to process images might be excellent for a person but the same result might not be good enough for another. Image enhancement is a cosmetic procedure i. e. it does not add any extra information to the original image. It merely improves the subjective quality of the images by working with the existing data. Image enhancement can be done in following two domains: The Spatial domain and The Frequency domain. This paper focuses on spatial domain techniques for image enhancement, with particular reference to point processing methods, histogram processing and spatial filtering.
