Contrast Enhancement, Noise, Image Enhancement
One of the problems of a contrast enhancement in practice is the noise boost-up, which limits the applications of the contrast enhancement in consumer products such as Digital TV. To resolve this issue, a novel approach for contrast enhancement is presented, which effectively prevents the visual amplification of a noise while the contrast is being enhanced. The proposed algorithm borrows the notion behind the Weber’s Law. Compared to typical approach which incorporates noise reduction algorithm before applying contrast enhancement, the proposed algorithm is free from possible blurring in the enhanced results.
