摘要: Polygon approximation is an important step in the recognition of planar shapes. Traditional polygonal algorithms handle only images that are related by a similarity transformation. The transformation shape as viewpoint changes with perspective camera general projective one. In this paper, we present novel method for closed curves invariant to polygons generated our algorithm from two images, homography, isomorphic. We also describe application form numeral recognition. demonstrate importance real-life applications like number plate recognition, aircraft and metric rectification.
