Implementation of Global Translation Registration for Arbitrary Image Pairs

This algorithm achieves global translation registration between arbitrary image pairs and is applicable to various image types, including but not limited to natural images, medical images, and satellite imagery. The implementation typically involves calculating similarity metrics (such as cross-correlation or mutual information) between the two images to determine optimal registration parameters. An optimization algorithm (e.g., gradient descent or exhaustive search) is then employed to refine the translation transformation. Key functions may include: 1) Preprocessing for intensity normalization, 2) Similarity computation using sliding window techniques, 3) Transformation optimization with convergence criteria. The algorithm demonstrates high robustness and accuracy, delivering exceptional performance in image registration tasks. It finds extensive applications in computer vision, image processing, and medical imaging fields, holding significant value for both research and practical implementations of image registration.
