SymmetryThe homography matrix is essential for perspective transformation across consecutive video frames. While existing methods are effective when the visual content between paired images remains largely unchanged, they rely on substantial, high-quality ...

A Fast Attitude Estimation Method Using Homography Matrix
Proceedings of the 2020 3rd International Conference on Computer Science and Software Engineering, 2020In this paper, a new algorithm is proposed to calculate the attitude estimation from two images. It is based on a new single homography matrix decomposition, which is faster than the traditional method. It provides a detailed analysis of the error propagation of the method.

Simultaneously Estimating the Fundamental Matrix and Homographies
IEEE Transactions on Robotics, 2009The estimation of the fundamental matrix (FM) and/or one or more homographies between two views is of great interest for a number of computer vision and robotics tasks. We consider the joint estimation of the FM and one or more homographies. Given point matches between two views (and assuming rigid geometry of the camera-scene displacement), it is well

Determinant of homography-matrix-based multiple-object recognition
SPIE Proceedings, 2013Finding a given object in an image or a sequence of frames is one of the fundamental computer vision challenges. Humans can recognize a multitude of objects with little effort despite scale, lighting and perspective changes. A robust computer vision based object recognition system is achievable only if a considerable tolerance to change in scale ...

Fundamental matrix and planar homographies in stereo vision
SPIE Proceedings, 2012ABSTRACT We describe the epipolar constraint that specifies the geometry of stereo vision. We consider the 3D structure reconstruction from multiple views through the new perspective of basing the reconstruction from directly estimated planar homographies instead of using techniques that are based on matched point pairs.

Accurate Object Tracking Based on Homography Matrix
2012 International Conference on Computer Science and Service System, 2012We present a novel object tracking framework that can efficiently track such 2-D affine motions of the object image. A coarse-to-fine tracking strategy is explored in the tracking framework. Firstly, the object image region is selected from the first frame, the scale-invariant feature (SIFT) extracted from the object image region is utilized as the ...

Depth-Camera Calibration Optimization Method Based on Homography Matrix
Proceedings of the 2019 International Conference on Robotics, Intelligent Control and Artificial Intelligence, 2019A self-calibration method of the depth-camera based on homography matrix is proposed to improve the accuracy and ease of use in calibrating the depth-camera. Firstly, the shortcomings of the existing self-calibration methods are pointed out, and the internal conversion model of the depth-camera is established.

Simplified homography matrix for a large-scale camera array system
Applied Optics, 2011We want to use a large-scale camera array system in which each camera is placed at the desired position to photograph a subject and later render images of the subject viewed from various directions or render images for a three-dimensional display. The homography matrix for each camera should be calculated in advance to correct the captured images.
