Fast Block-Matching Motion Estimation Using Modified Diamond Search Algorithm
This paper propose a new block matching algorithm for motion estimation. Four different block matching algorithms using for motion estimation are evaluated where no of computation to find out best match and peak signal to noise ratio (PSNR) are used to find out most optimal algorithm. Four different block matching algorithm are implemented in MATLAB. Each algorithm is evaluated using PSNR and s...
متن کاملModified Cross Hexagon Diamond Search Algorithm for Fast Block Matching Motion Estimation
Abstract—The most essential part in Video Coding Standards is Motion Estimation. But, Motion Estimation itself consumes more than half of the coding time to encode. To reduce the computational complexity, the time required for Motion Estimation should be reduced for which efficient algorithms are required. A new Modified Cross Hexagon Diamond Search (MCHDS) algorithm is proposed which will redu...
متن کاملDirectional Cross Diamond Search Algorithm for Fast Block Motion Estimation
In block-matching motion estimation (BMME), the search patterns have a significant impact on the algorithm’s performance, both the search speed and the search quality. The search pattern should be designed to fit the motion vector probability (MVP) distribution characteristics of the real-world sequences. In this paper, we build a directional model of MVP distribution to describe the directiona...

متن کاملA new diamond search algorithm for fast block-matching motion estimation
Based on the study of motion vector distribution from several commonly used test image sequences, a new diamond search (DS) algorithm for fast block-matching motion estimation (BMME) is proposed in this paper. Simulation results demonstrate that the proposed DS algorithm greatly outperforms the well-known three-step search (TSS) algorithm. Compared with the new three-step search (NTSS) algorith...
