Abstract

Image enhancement (IE) goals to enhance the visible appearance of a picture, without affecting the original attributes (i.e.,) Image contrast is adjusted and noise is removed to supply higher excellent picture. Hence IE is one of the maximum important responsibilities in image processing (IP). Enhancement is classed into kinds spatial domain (SD) enhancement and frequency domain (FD) enhancement.SD enhancement acts upon pixel value whereas FD enhancement acts on the Fourier transform (FT) of the image. The enhancement techniques for use depend on modality, climatic and visual angle and so on. On this paper, we present a survey on diverse present IE strategies.
