Semi-Global Stereo Matching with Surface Orientation Priors

, 2017
Semi-Global Matching (SGM) is a widely-used efficient stereo matching technique. It works well for textured scenes, but fails on untextured slanted surfaces due to its fronto-parallel smoothness assumption.

The Acts of Eadburg: drypoint additions to Oxford, Bodleian Library, MS Selden Supra 30

Early Medieval Europe, Volume 34, Issue 2, Page 195-230, May 2026.
In 1913, two drypoint additions were identified in Oxford, Bodleian Library, MS Selden Supra 30 (SS30), an eighth‐century Southumbrian copy of the Acts of the Apostles. It was suggested that these additions, cut into the membrane of p. 47, were abbreviations of the Old English female name, Eadburg. Just over a century later, many more drypoint markings

Modelling the appearance of heritage metallic surfaces [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014
Polished metallic surfaces exhibit a high degree of specularity, which makes them difficult to reproduce accurately. We have applied two different techniques for modelling a heritage object known as the Islamic handbag. Photogrammetric multi-view stereo

Integrating stereo and photometric stereo to monitor the development of glaucoma [PDF]

Image and Vision Computing, 1990
Abstract Progress on a system to monitor the development of glaucoma by measuring the topography of the optic disk is reported. The need for an accurate method for doing this using passive vision is explained. Sparse depth measurements from stereo matching of blood vessels provide insufficient constraint for reconstructing the surface of the optic ...

Versatile CRISPR‐Cas Tools for Gene Regulation in Zebrafish via an Enhanced Q Binary System

Advanced Science, Volume 13, Issue 23, 23 April 2026.
This study introduces CRISPR‐Q, a transgenic CRISPR‐Cas system leveraging the QFvpr/QUAS binary expression platform in zebrafish. CRISPR‐Q overcomes previous challenges in achieving stable and efficient gene regulation. By enabling precise spatiotemporal control of transcript knockdown (CRISPR‐QKD) and gene activation (CRISPR‐Qa), it provides a ...

Underwater Target 3D Reconstruction via Integrated Laser Triangulation and Multispectral Photometric Stereo

Journal of Marine Science and Engineering
With the gradual application of 3D reconstruction technology in underwater scenes, the design of vision-based reconstruction models has become an important research direction for human ocean exploration and development. The underwater laser triangulation

Respiratory‐Limbic Coupling via a Thalamic Circuit Alleviates Anxiety

Advanced Science, Volume 13, Issue 24, 27 April 2026.
This study delineates a conserved preBötCGlu→PVT→CeA circuit that gates anxiety and respiration. Activation of this circuit is anxiolytic and respiratory‐stabilizing, while its inhibition has the opposite effect. Mechanistically, PVT exerts its anxiolytic action via a disinhibitory microcircuit: its inputs preferentially target CeL GABAergic neurons ...

Uncalibrated Near-Light Photometric Stereo [PDF]

Proceedings of the British Machine Vision Conference 2014, 2014
In this work we solve the uncalibrated photometric stereo problem with lights placed near the scene. We investigate different image formation models and find the one that best fits our observations. Although the devised model is more complex than its far-light counterpart, we show that under a global linear ambiguity the reconstruction is possible up ...
