Estimation of Motion Vector Parameters Using Modified Diamond Search

Fast motion estimation using modified diamond search patterns - Electronics Letters

A fast block motion estimation algorithm is proposed using modified diamond search patterns. This algorithm utilises the directions and magnitudes of motion vectors between interblocks and uses a smaller number of seach points than conventional diamond search patterns. Simulation results show that the proposed method significantly improves computational speed over other fast motion estimation a...

Motion Vector Estimation Search using Hexagon-Diamond Pattern for Video Sequences, Grid Point and Block-Based

Grid and block-based motion vector estimation techniques are proposed for motion tracking in video sequences. The grid technique is referred to the hexagon-diamond pattern. While, block-based technique is referred to 16 × 16 pixels of blocks in a single frame in video sequences. The hexagon and diamond pattern is applied onto the 16 × 16 pixels blocks in a single frame for motion tracking purpo...

Efficient tree structured motion estimation using successive elimination - Vision, Image and Signal Processing, IEE Proceedings-

In H.264/AVC, tree structured motion estimation enhances the coding efficiency significantly while dramatically increasing the computational complexity of block matching. In the paper, a successive elimination algorithm (SEA) is implemented in tree structured motion estimation with a simple and effective method to determine the initial motion vector, which exploits the strong correlation among ...

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...
