{"title":"An New Adaptive Quantization To Reduce Blocking Effect","authors":"Cheol-Hong Min, Sanghee Cho, K. Lim, Heesub Lee","doi":"10.1109/ICCE.1998.678345","DOIUrl":"https://doi.org/10.1109/ICCE.1998.678345","url":null,"abstract":"In this paper, we present a method to reduce the blocking effects in block based coding schemes. Based on our observation, the blocking effect appears mainly in the region with fast or complex motion which is not well compensated. But this region tends to be coarsely quantized in the traditional method using only the spatial activity measure. [2] In order to quantize this region finely enuogh, we introduce a new activity measure, the slope activity. By using this measure together with the spatial activity measure, we perform the adpative quantization for each MB in a picture. Our approach shows superior picture quality compared to the MPEG TM5. Particularly in fast or complex motion scenes, the blocking effects in the object boundaries are much suppressed than that of MPEG TM5, therefore generating much smoother image for comfortable viewing. Also, our method shows higher PSNR than that of the MPEG TM5. I . INTRODUCTION The MPEG standard provides a fine method which can compress moving pictures with low bitrates [l], [2]. But due to its lossy characteristics, distortions are highly visible if not enough bits are used. Many different types of distortions are inevitable if this kind of compression techinique is used [4]. Above all, the blocking effect is known to be the major artifact in a block based coding scheme. Based on our observations of video sequences, blocking effect appears mainly in the regions having nontranslational, fast, or random motion. The reason is that motion compensation itself is done roughly in these regions leaving lots of disparities along the MB(Macro Block) boundaries in the prediction error image. And in traditional approaches, many MBs in these regions tend to be quantized coarsely by using only the spatial activity [2], [3]. So the disparities in the MB boundaries are not well compensated. And if these regions exist in successive frames in a video sequence, blocking artifacts are quite noticeable. To resolve this limitation of the spatial activity measure, we propose a new activity measure, a slope activity measure, by which we can find the region with the complex motion. Using this measure together with the spatial activity measure, we perform the adaptive quatization of each MB in a picture. 11. DETECTION OF THE BLOCKY REGION In the previous section, we pointed out that more blocking effects are generated in the regions where the motion is not well compensated. Fig. l.(a) shows a difference image of the football sequence. We can see that the lots of disparities in the MB boundaries mainly appear in the regions with complex motion. These disparities are similar to blockiness, in order to detect these region, we adopt Mean Square Difference of Slope(MSDS) which detects the degree of blockiness on the boundaries by measuring the gradient between the neighboring blocks along the boundary [5]. We apply this MSDS criterion with some modification to difference image and detect the not well motion compensated regions.
