Image Registration

Image registration is the process of aligning two or more images of the same object or scene taken at different times, from different angles, or using different equipment. The goal is to match corresponding points or features so that the images can be accurately compared, combined, or analyzed. This technique is vital in areas like medical imaging, where it helps doctors see the same body part over time, or in remote sensing, for updating maps. Essentially, it ensures that the images are in the same coordinate system, enabling meaningful interpretation and analysis.
