STN-Homography: Direct Estimation of Homography Parameters for Image Pairs

, 2019
Estimating a 2D homography from a pair of images is a fundamental task in computer vision. Contrary to most convolutional neural network-based homography estimation methods that use alternative four-point homography parameterization schemes, in this ...

Inclinometer Assembly Error Calibration and Horizontal Image Correction in Photoelectric Measurement Systems

Sensors, 2018
Inclinometer assembly error is one of the key factors affecting the measurement accuracy of photoelectric measurement systems. In order to solve the problem of the lack of complete attitude information in the measurement system, this paper proposes a new

Post‐Acquisition Image‐Based Localization for High Resolution Thermal and Visible/Shortwave Infrared Images With Application to the Lunar Trailblazer Mission

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract The Lunar Trailblazer mission aimed to assess the presence of water on the lunar surface using imaging spectroscopy in visible shortwave infrared (VSWIR) coupled with high‐resolution multispectral imaging in thermal midwave‐infrared (MWIR), captured simultaneously over the same target from orbit around the Moon with two different instruments ...

An Angler‐Friendly AI Pipeline for Self‐Reporting and Automatic Catch Analysis in Recreational Fisheries

Fish and Fisheries, Volume 27, Issue 3, Page 627-642, May 2026.
ABSTRACT Monitoring recreational fisheries is difficult: anglers are widely dispersed, gear and practices vary, and many species are involved, which leads to fragmented and scarce data. To address these issues, we developed an Artificial Intelligence (AI) pipeline that turns angler‐reported photos into standardised records of catch composition and ...

System Integration and Field Testing of Low‐Cost Autonomous Platooning Platforms: Collision Avoidance Scenario

Journal of Field Robotics, Volume 43, Issue 2, Page 847-878, March 2026.
ABSTRACT This paper presents the development and validation of a scalable platooning system based on the predecessor‐following (PF) topology, designed for low‐cost follower platforms. It integrates key technologies such as localization, path planning, profile generation, and low‐level control to create a practical solution.

Dynamic estimation of homography transformations on the special linear group for visual servo control

2009 IEEE International Conference on Robotics and Automation, 2009
In the last decade, many vision-based robot controllers have been designed using Cartesian information encoded in the homography transformation that links two images of a planar object. For any approach, the performance of the closed-loop system depends on the quality of the homography estimates obtained.

A New GRIME2: Using an Octagon Calibration Target and Trail Camera to Measure Stream Water Level Over a 2‐Year Period

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract GaugeCam Remote Image Manager Educational 2 (GRIME2) is a free, open‐source Windows application for water level measurement in surface water bodies using ground‐based time‐lapse imagery. We evaluated a new “stop sign” (i.e., octagon shape) calibration target and GRIME2 algorithms by comparing results to other measurement methods over a 26 ...

MVI‐Depth: Multi‐View Indoor Depth Estimation Based on the Fusion of Semantic Information

CAAI Transactions on Intelligence Technology, Volume 11, Issue 1, Page 98-110, February 2026.
ABSTRACT Compared to monocular depth estimation, multi‐view depth estimation often yields more accurate results. However, traditional multi‐view depth estimation methods often fail to leverage semantic information fully and struggle to effectively fuse information from multiple views, leading to suboptimal prediction performance in challenging ...
