IET Computer Vision, Volume 20, Issue 1, January/December 2026.We propose InceptionMamba and InceptionConv3D modules to enhance feature matching distinctiveness and cost volume regularisation in unsupervised multi‐view stereo by capturing multi‐granularity cues from varying viewpoints and depth planes. Integrated into CL‐MVSNet as INT‐MVSNet, our approach achieves state‐of‐the‐art performance on DTU and Tanks ...

Epipolar geometry and stereo matching algorithm for underwater fish-eye images
International Journal of Advanced Robotic Systems, 2018 A fish-eye lens achieves a large field of view at the cost of image distortion, and underwater imaging by a fish-eye lens introduces refraction when light passes through the different medium.

Epipolar Plane Image Rectification and Flat Surface Detection in Light Field
Journal of Electrical and Computer Engineering, 2017 Flat surface detection is one of the most common geometry inferences in computer vision. In this paper we propose detecting printed photos from original scenes, which fully exploit angular information of light field and characteristics of the flat ...

Multi‐Camera Pairwise Calibration Through Joint Optimization Method
IET Image Processing, Volume 20, Issue 1, January/December 2026.We propose a novel multi‐camera calibration method for systems with non‐overlapping fields of view. By establishing local constraints between adjacent cameras and performing staged joint optimization, our approach estimates intrinsic/extrinsic parameters while dynamically selecting optimal calibration paths via camera topology graphs and confidence ...

IEEE AccessBack Projection, a fundamental process in 3D reconstruction, requires depth information to restore 2D pixels to 3D coordinates. However, since depth information is lost during the projection of 3D space onto a 2D plane, accurate reconstruction is ...

AN INTEGRATED RANSAC AND GRAPH BASED MISMATCH ELIMINATION APPROACH FOR WIDE-BASELINE IMAGE MATCHING [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015 In this paper we propose an integrated approach in order to increase the precision of feature point matching. Many different algorithms have been developed as to optimizing the short-baseline image matching while because of illumination differences and ...

Towards Event‐Based Stereo Depth Estimation at Millisecond Resolution
IET Image Processing, Volume 20, Issue 1, January/December 2026.We introduce MADNet‐ε$\varepsilon$ , a lightweight architecture for event‐based stereo matching. Unlike state‐of‐the‐art models designed for this task that can barely achieve 30 FPS, the MADNet‐ε$\varepsilon$ design enables disparity inference at more than 140 FPS without compromising accuracy, thus dramatically reducing the gap with the microseconds ...
