A Brief Survey on Different Contrast Enhancement Techniques
Authors(1) :-S. Praveena Contrast enhancement is used to either increase the contrast of an image with low dynamic range or to bring out image details that would otherwise be hidden. Generally, the contrast enhanced image looks better than the original image. The contrast variations in an image vary with different aspects like illumination, color, scene etc. So many approaches are developed to increase the contrast of an image with abnormal contrast levels. This paper outlines a brief survey over different contrast enhancement approaches. Based on the domain the contrast enhancement takes place, all the earlier approaches are classified as spatial domain and transform domain approaches. Further based on the fashion, they are categorized as local contrast enhancement and global contrast enhancement approaches. All the possible constraints with contrast enhancement techniques is represented here.
