Image enhancement can be classified into different methods. Adaptive histogram equalization, histogram equalization, decor relation stretch, image adjust and image noise. Adaptive Histogram Equalization (AHE) is mainly used in image processing techniques and it is used to improve the contrast in the images. Histogram Equalization is a contrast adjustment using the image histogram, it is usually increase the global contrast of each images. Apply the décor relation stretch to multi channel image. Image adjust is mainly focus on to adjust the contrast and quality of the image. Image noise is used to add the noise in an image.
