A New Survey on Block Matching Algorithms in Video Coding
Block matching motion estimation is the essence of video coding systems. This paper is a survey of the existing block matching algorithms used for motion estimation in video coding. The algorithms that are surveyed in this paper are widely accepted by the video coding community and have been used in implementing various standards, ranging from MPEG1/H.261 to MPEG10/H.264. The aim of this review...
متن کاملAdaptive motion tracking block matching algorithms for video coding
In most block-based video coding systems, the fast block matching algorithms (BMA’s) use the origin as the initial search center, which may not track the motion very well. To improve the accuracy of the fast BMA’s, a new adaptive motion tracking search algorithm is proposed in this paper. Based on the spatial correlation of motion blocks, a predicted starting search point, which reflects the mo...
متن کاملA Rate-Constrained Block Matching Algorithm for Video Coding
The Rate Constrained Block Matching Algorithm, (RC-BMA), introduced in this paper, jointly minimizes Displaced Frame Di erence (DFD) variance and entropy or conditional entropy of motion vectors for determining the motion vectors. It is intended for use in low rate video coding applications where the contribution of the motion vector rate to the overall coding rate might be signi cant. The DFD ...
متن کاملA lightweight genetic block-matching algorithm for video coding
In this paper, a lightweight genetic search algorithm (LGSA) is proposed. Different evolution schemes are investigated, such that the control overheads are largely reduced. It is also shown that the proposed LGSA can be viewed as a novel expansion of the three-step search algorithm (TSS). It can be seen from the simulation results that the performance of LGSA is very similar to that of FSA, and...
