The equivalence of two definitions of compatible homography matrices
Pattern Recognition Letters, 2020 In many computer vision applications, one acquires images of planar surfaces from two different vantage points. One can use a projective transformation to map pixel coordinates associated with a particular planar surface from one image to another.

Bilevel Progressive Homography Estimation Via Correlative Region-Focused Transformer
Computer Vision and Image Understanding, 2023We propose a novel correlative region-focused transformer for accurate homography estimation by a bilevel progressive architecture. Existing methods typically consider the entire image features to establish correlations for a pair of input images, but irrelevant regions often introduce mismatches and outliers.

Structure-Guided Image Inpainting Using Homography Transformation
IEEE Transactions on Multimedia, 2018In this paper, we present a novel structure-guided framework for exemplar-based image inpainting to maintain the neighborhood consistence and structure coherence of an inpainted region. The proposed method consists of a data term for pixel validity and boundary continuity, a smoothness term to depict the compatibility of neighboring pixels for ...

A homography transform based higher-order MRF model for stereo matching
Pattern Recognition Letters, 2014Stereo matching is one of the most important and fundamental topics in computer vision. It is usually solved by minimizing an energy function, which includes a data term and a smoothness term. The data term consists of the matching cost, and the smoothness term encodes the prior assumption that the surfaces are piecewise smooth.

Video Stabilization Algorithm Based on Kalman Filter and Homography Transformation
2017The camera systems are usually suffered from random jitter. In this paper, a new method based on Kalman filter and homography transformation is proposed to stabilize the unstable video. Firstly, the SURF (Speed-Up Robust Feature) point-feature matching algorithm is employed to find the corresponding matching points between two consecutive frames, and ...

GA-based Homography Transformation for Vision Rectification in Robot Drawing System
Proceedings of the 44th IEEE Conference on Decision and Control, 2006A robot drawing platform supporting five degrees of freedom (x, y, and z translation, z-rotation, and pitch) of a brush-pen motion has been under development in our laboratory. The platform is aimed at studying Chinese painting and calligraphy. Both replication of existing works and rendition of new are planned.

High-precision Image Mosaic Algorithm Based on Adaptive Homography Transform
2021 40th Chinese Control Conference (CCC), 2021The Unmanned Aerial Vehicle (UAV) image mosaic is a research hotspot of digital image processing in recent years, which has extensively application prospect. The existing algorithms are sensitive to aerial images mosaic with large scale and perspective differences, and have the disadvantages of poor accuracy and image distortion, which can not obtain ...

Homography transform enhance CNN prediction accuracy on image classification
Applied and Computational Engineering, 2023Convolutional Neural Network (CNN) image classification is a well-established algorithm that has been implemented in many fields. Benefit from the digitalization process and the exponential increase in the base of smart devices, this algorithm can be applied to even more traditional or casual contexts in the future driven by the trend of Internet of ...
