In this paper, we proposed a quality enhancement scheme to deal with low- and high-exposure images. The proposed scheme is composed of three parts: face detection, dominate color detection, and quality enhancement. After face detection, dominant color detection is used to compute the color information of the detected facial area. A simple rule is used to determine the exposure level of an image. According...
In this paper, we present a quality enhancement scheme for endoscopic images. Traditional algorithms might be able to enhance the image contrast, but possible over-enhancement also lead to bad overall visual quality which prevents surgeons from accurate examination or operations of instruments in Minimal Invasive Surgery (MIS). Our proposed scheme integrates the well-known retinex algorithm with a...
