The homography corresponds to a 3×3 matrix which transfers image points between two images of a planar scene or two images captured by cameras under purely rotational motion. Homography estimation is crucial to many computer vision tasks involving multi-view geometry. Unlike most existing algorithms using sparse information extracted from images, this paper proposes a dense homography estimation method...
The image registration based on the features of the image is a major research direction.The points feature is used in traditional registration methods,but the lines and other basic features are ignored. So,an image auto registration method based on natural heterogeneous features is given out. First, the feature points are detected using Harris feature detector and the feature line segments are detected...
Image registration based on the features of an image is a major research direction. It is common sense that there are many problems in traditional feature registration including a large amount of computations, high complexity and low accuracy. So, an auto image registration method based on natural characteristic points and global homography is proposed in this paper. In this method, firstly, the feature...
A highly accurate feature point matching method for stereo was proposed. It was proved that the homography between corresponding feature windows can be approximated by an affine model. Then the projective distortion of corresponding feature windows was estimated and rectified by a fast iterative scheme, at the same time, the location error of corresponding feature points arising at the detection stage...
