In this paper, we implement full search algorithm and three-step search method to simulate transmission of 256×256 images. These search algorithms enable efficient motion vector estimation by examining all possible positions (full search) or using a hierarchical approach (three-step search) to locate specific patterns within image frames. The implementation typically involves creating nested loops for exhaustive pattern matching in full search, while three-step search utilizes a coarse-to-fine strategy with progressively smaller search windows. Through this simulation, we can better understand the principles of image processing and data transmission, while practically applying these algorithms for motion compensation and block matching. This approach provides enhanced learning opportunities for exploring digital image processing techniques, allowing deeper investigation into optimization methods and computational efficiency in video coding applications.
