Syed Ali Zia, Nasir Ahmad . Improving the Efficiency of Block Matching Algorithms using Optimization Techniques. International Journal of Computer Applications. 175, 14 ( Aug 2020), 22-25. DOI=10.5120/ijca2020920622
Block matching techniques are efficient methods among existing motion estimation methods according to literature. Block matching techniques mostly focuses on the factors like estimation accuracy and computational complexity. There are few methods among the existing search methods which can provide satisfactory result at a very low computational cost but none of these methods can effectively jump out of the local optimum when processing large motion sequences. The proposed search method mainly adopts threshold values for early termination of block-matching in order to remove unnecessary search and is evaluated and compared together in terms of signal to noise ratio and search point’s avoidance per macro block for different block size and search area. Experimental results showed that the proposed method has achieved significant improvement on both Estimation accuracy and computational complexity.
