Color Image Enhancement Techniques:
A Critical Review
Abstract
Image enhancement is one of the key issues in high quality pictures such as digital camera and HDTV. Since
Image clarity is very easily affected by lighting, weather, or equipment that has been used to capture the image.
These conditions lead to image may suffer from loss of information. As a result, many techniques have
developed known as image Enhancement techniques to recover the information in an image. This paper presents
a literature review on some of the image Enhancement techniques for color image enhancement like, Contrast
Stretching, Histogram Equalization and its improvement versions, Homomorphic Filtering, Retinex, and
Wavelet Multiscale Transform. Comparison of all the techniques concludes the better approach for its future
