Description: Digital image processing means converts the image signal into a digital form and processed by computer process them. Image enhancement is the process of digital image processing, a method often used, it is to improve the image quality plays an important role. This article first for an overview of the principles of image enhancement, and image enhancement methods for classification and gives the histogram enhancement, contrast enhancement, smoothing and sharpening enhancement of several commonly used methods of theoretical foundation, through Matlab experimental results of actual processing results to compare the advantages and disadvantages of various algorithms, discuss different techniques enhancement algorithm, and its performance evaluation image enhancement methods.
