Image Correspondence

Image correspondence is the process of identifying and matching the same points or features across different images. This technique helps in understanding how a scene or object appears from different viewpoints or at different times. For example, it allows a computer to recognize that two different photos show the same building, even if taken from different angles. By linking these similar features, image correspondence enables applications like 3D reconstruction, navigational mapping, and augmented reality, providing a cohesive understanding of the scene from multiple images.
