A Survey of Image Enhancement Techniques with its Applications and Problems

Image Enhancement is one of the predominant and problematic strategies in Image research. The intention of image enhancement is to reinforce the visible appearance of an image, or to provide a “better turn into illustration for future automated image processing. Many images like medical images, satellite image, aerial images and even real existence portraits endure from poor contrast and noise. It is necessary to enhance the contrast and dispose of the noise to expand imageo pleasant. Image Enhancement techniques which improves the first-rate (readability) of images for human viewing, casting off blurring and noise, growing distinction, and revealing important points are examples of enhancement operations. The enhancement technique differs from one discipline to yet another in keeping with its objective. The prevailing procedures of image enhancement can be classified into three classes: wavelength compensation and image dehazing (WCID), Contrast Limited Adaptive Histogram Equalization (Clahe)and blend-CLAHE. In this paper, the present an outline of image enhancement processing methods in spatial domain. Additional exceptionally, the categorise processing approaches established representative strategies of image enhancement.
