“…The proposed method is also compared with the GOBMC scheme. 3 The experiments have been conducted using six video sequences: Football, Table Tennis, and Flower in the 352ϫ 240 pixels/frame format, and Miss America, Claire, and Salesman in the 352 ϫ 288 pixels/frame format. These sequences are transmitted with a bit rate of 2000 bits/frame on average and are partitioned using the RWMC scheme discussed in Ref.…”

We present two new techniques for reducing blocking artifacts in motion compensated frames. These techniques can be applied generally to motion compensated frames obtained by employing any partitioning schemes. In the first technique, the weighting coefficients of the overlapped block motion compensation are modeled with fuzzy relations. These fuzzy relations are formed based on two fuzzy sets, which define the closeness of a given pixel to the block boundaries in the horizontal and vertical directions, respectively. The second technique uses the similarity between a set of pixels inside a partitioned region and that on the borders to modify the border pixels. Simulations conducted on several benchmark video sequences indicate that the proposed techniques can improve the subjective quality of the frames as well as reduce the prediction error. © 2006 SPIE and IS&T.

Efficient motion estimation is an important problem because it determines the compression efficiency and complexity of a video encoder. Motion estimation can be formulated as an optimization problem. This paper starts with an introduction of basic motion estimation problem and discusses issues specific to video motion estimation of two types FSBME &VSBME estimations. This paper in three sections presents a overview of block matching ME problem in three direction 1.computation complexity reduction 2.accurate representing true motion 3.improving coding efficiency.

“…More recently, Calzone et al [18], Wiegand et al [19], and Schuster and Katsaggelos [20,21], considered quad-tree-based VSBM coding schemes that refine the motion estimates of FSBM MC codecs by splitting 16 × 16 macroblocks. The schemes achieve compression through joint optimization of all associated costs by means of a Lagrangian cost function.…”
