The main function of image enhancement is to improve the visual appearance of an image. Many images such as remote sensing images, medical images, electron microscopy images, satellite images and even real life photographs suffer from poor contrast and noise. So it is necessary to increase the contrast and remove the noise to enhance image quality. This paper presents a literature review on various image Enhancement techniques such as wavelet transform, Contrast Stretching, Histogram equalization, Retinex, etc. Comparison of various techniques concludes the better approach for the future research. Keywords- Discrete Wavelet Transform, Fingerprint enhancement, Histogram Equalization, Image Enhancement, Retinex, Spatial and Frequency Domain.Read More
