Image Enhancement Techniques Using Matlab Functions

In image processing one of the most frequently used techniques is image enhancement. In order to obtain a good quality image, these techniques can improve the graphical appearance and image features. In real life, various images such as aerial images, medical images of different categories may suffer from the drawbacks of noises and poor contrast. To enhance the visibility of an image by removing all these drawbacks, image enhancement techniques are utilized. The improved picture results in better vision to the human eye. The image enhancement techniques are based on objective or application. In this work, to judge the effectiveness of image enhancement techniques, many techniques such as contrast enhancement, histogram equalization, and filtering, etc. have been applied on various images using Matlab.
