A Fast Block Matching Algorithm Based on Motion Vector Correlation and Integral Projections
The block based motion estimation technique is adopted by various video coding standards to reduce the temporal redundancy in video sequences. The core of that technique is the search algorithm implemented to find the location of the best matched block. Indeed, the full search algorithm is the most straightforward and optimal but computationally demanding search algorithm. Consequently, many fa...
متن کاملBlock motion estimation based on selective integral projections
Existing fast block motion estimation algorithms, which try to reduce the number of search points, utilize the motion vector (MV) characteristics of high spatial correlation as well as center-biased distribution, in predicting an initial MV. Even though they provide good performance for slow motion sequences, they suffer from poor accuracy for fast or complex motion sequences. In this paper, we...

متن کاملA Fast Adaptive Block-matching Motion Estimation Algorithm
In this work, we have developed a new bio-inspired neural network algorithms for blockbased motion estimation. The main goal is to bridge the gap between algorithmic and biological vision by suggesting a bio-inspired motion estimation model based on neural network. We simplify the matching criterion for the block matching algorithm to reduce the hardware complexity and a number of input ports w...
متن کاملFast 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...
