In this paper, we propose a novel contrast enhancement technique, referred to as the classification based histogram specification framework (CHSF). CHSF consists of offline training and online enhancement processes. In the offline training process, training images are classified into multiple classes, and then the feature vector that can discriminate the(More)
This paper presents a frame-adaptive deblocking filter that can improve the coding efficiency of the H.264/AVC standard. In the proposed deblocking scheme, the optimal filter coefficients are found by minimizing the mean square error between the block edge in each decoded frame and that in the corresponding original frame. Experimental results show that the(More)
