Localized image enhancement using depth map

The main objective of this paper is to propose a method for localized image enhancement. This method can be highly beneficial in medical purposes, like Laminography, or in enhancing images captured under non-uniform illumination. Along with a depth map, a spatial queue-based data structure is used to properly locate the area to be enhanced in the captured scene. There are automated techniques to detect areas where enhancement is required, but these methods suffer heavily with false detections, which, in turn, deteriorate the perceptual quality of the image. In the proposed algorithm, the area to be enhanced can be detected exactly with a minimum user intervention. After detecting, the area is enhanced using a singular value decomposition (SVD) based technique which preserves the color information of the scene and can enhance the scene in real time.
