Efficient image enhancement techniques for real-time processing

Abstract

In this paper, we propose an image enhancement technique for red-time processing with less calculation. The proposed algorithm carries out contrast enhancement and color correction at the same time. Contrast enhancement uses the spatial reduction technique, thus enabling to lessen the amount of calculation by using the image created by such method. In addition, the value of probability density was used to control any sudden image brightness. The proposed algorithm consists of four blocks including the reduction filter, judgment block, contrast enhancement and Color correction. The algorithm of color correction was done by the method to control the saturation selectively with using the color information of input image.
