Image Enhancement is one of the challenging issues in computer vision and image processing. The major goal of image enhancement is to increase the quality of image with respect to contrast and visual appearance or structural appearance without any degradation in the input image. The enhancement techniques mainly used for the identification of important features more easier by eliminating noise and other artifacts in an image. There are many image enhancement techniques existed which are mainly

The spatial domain enhancement techniques basically deal with image intensity values or pixels and in second domain an image is transformed into frequency domain using fourier transforms, etc. This paper mainly explores various special domain image enhancement techniques which provides better contrast, visual appearance and further leads to improvement of image quality. Especially histogram equalization is a prominent enhancement method which is used for contrast adjustment using histograms so that quality of image has been improved.
