Homography Ranking Based on Multiple Groups of Point Correspondences

open access: yesSensors, 2021
Homography mapping is often exploited to remove perspective distortion in images and can be estimated using point correspondences of a known object (marker). We focus on scenarios with multiple markers placed on the same plane if their relative positions

Unsupervised deep homography with multi‐scale global attention

open access: yesIET Image Processing, 2023
Homography estimation serves an important role in many computer vision tasks. Depending heavily on hand‐craft feature quality, traditional methods degenerate sharply in scenes with low texture.

Aggregation of Convolutional Neural Network Estimations of Homographies by Color Transformations of the Inputs

open access: yesIEEE Access, 2020
The standard approach to the estimation of homographies consists in the application of the RANSAC algorithm to a set of tentative matches. More recent strategies based on deep learning, namely convolutional architectures, have become available.
