This need has driven the development of a large number of corner detectors.
Shi, j., & tomasi, c. This need has driven the development of a large number of corner detectors. Corner detection is used in computer vision systems to find features in an image. Detected corners provide important information for localizing and understanding shapes in 3d scenes. That means, we have to maximize the second term. A corner in an image i is given at a pixel p where two edges of dierent directions intersect.
