Homography in image processing
WebHomography estimation is a technique used in computer vision and image processing to find the relationship between two images of the same scene, but captured from different viewpoints. It is used to align images, correct for perspective distortions, or perform image stitching. In order to estimate the homography, a set of corresponding points between … Web5 feb. 2024 · For this article, I will discuss two topics about image processing: Homography Matrix & Template Matching. Homography transformations. Homography is defined as mapping between two different projections of an image and is represented by a 3x3 transformation matrix in a homogenous coordinates space.
