Projective Transformation

A projective transformation is a way to mathematically change the appearance of an image or object, simulating how it looks when viewed from different angles or perspectives. It preserves straight lines but can stretch, skew, or shift parts of the image, much like how a photograph taken from a slight side angle appears distorted compared to a head-on shot. This transformation is used in computer graphics, image processing, and vision to manipulate images so they resemble different viewpoints, enabling tasks like perspective correction, 3D modeling, and augmenting visual data.
