Implementation of Image Enhancement Techniques

Abstract

Image enhancement is a process which modifies the pixels of an image up to certain magnitude. It results in more subjectively pleasing image for human and machine analysis for some specific applications such as-X-Ray, fingerprinting, modelling photographs etc. It improves the visual appearance of pixels of an image. Pixels of an image can be manipulated in frequency as well as spatial domain. There are different image enhancement techniques comes under point processing in spatial domain such as-negative of an image, contrast stretching, thresholding, power law, logarithmic and grey level slicing.
