Abstract

An enhancement method is widely used in several applications is based on the image quality is most important in the human interpretation. The enhancement methods to increasing an image visual quality, it provides more methods or techniques. The main objective of this techniques to process an image to improve visual quality that results more appropriate than original image and used large number of techniques and methods are used. The aim of this paper to reviewing different image enhancement algorithms or to increase image contrast in low-quality image and also enhanced specific extents like medical image, satellite image and infrared image. This technique focused on spatial domain method with explicit respect to histogram processing method, curvelet transform and point processing method. We use various image quality measures, which is measured the performance based on the parameter matrix like Peak Signal to Noise Ratio, Mean Square Error, Average Difference, Normalized Absolute Error.
