Identity Invariance

Identity invariance is the property that an object or person remains recognizable despite changes in appearance, position, or context. For example, whether you see a person from the front, side, or at different angles, they are still identifiable as the same individual. In a broader sense, it means that certain core features or characteristics stay consistent even when other aspects vary. This concept is important in fields like computer vision and psychology, helping systems and humans understand that who or what something is doesn’t change with superficial differences.
