Block-based transform coding is the most popular approach for image and video compression. The objective measurement of blocking artifacts plays an important role in the design, optimization. and assessment of image and video coding systems. This paper presents a new algorithm for measuring blocking artifacts in images and videos. Instead of using the(More)
In this paper, we present a novel unequal loss protection (ULP) algorithm for robustly transporting datapartitioned MPEG-4 video over the packet erasure networks. To minimize the overall distortion in a frame, a redundancydistortion optimization scheme is developed by optimally assigning the given amount of forward error correction (FEC) codes between(More)
A new mesh generation algorithm is proposed for mesh-based video coding. The still segmentation result of watershed segmentation is projected onto motion segmentation result of change region detection in proposed algorithm. Therefore, mesh presentation generated by our new method is able to reflect both spatial and temporal features of input video sequence.(More)
