To reduce the computational complexity of motion estimation algorithms and enhance the reliability of sequential image super-resolution reconstruction, we propose an effective three-step search algorithm. This algorithm employs a multi-step search strategy that leverages the center-biased distribution characteristics of motion vectors and parallel processing principles. It replaces conventional square templates with diamond-shaped small templates for refined searching in optimal matching regions, thereby improving search accuracy. Implementation involves coarse-to-fine hierarchical searching with adaptive pattern switching. Experimental results demonstrate significant reduction in computational time while maintaining high search precision.
