Democratising Multi‐Projector Displays
Computer Graphics Forum, EarlyView.Spatially augmented reality (SAR) transforms large, surround, collaborative experiences out of VR/AR headsets to the real world by merging content from projectors with the physical environment. This detailed state‐of‐the‐art survey reports on the advancements in multi‐projector aggregation and hardware technologies used to achieve SAR and build ...

Stereo-photometric techniques for scanning micrometer scale
Virtual Archaeology Review, 2015 This paper describes a new methodology based on the combination of photogrammetric and stereo-photometric techniques that allows creating virtual replicas reproducing the relief in micrometric scale, with a geometric resolution until 7 microns.

Semi-Calibrated Near Field Photometric Stereo [PDF]
2017 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2017 3D reconstruction from shading information through Photometric Stereo is considered a very challenging problem in Computer Vision. Although this technique can potentially provide highly detailed shape recovery, its accuracy is critically dependent on a numerous set of factors among them the reliability of the light sources in emitting a constant amount

The Acts of Eadburg: drypoint additions to Oxford, Bodleian Library, MS Selden Supra 30
Early Medieval Europe, EarlyView.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

The hidden science of haptics: A pedagogical review of tactile evaluation in cosmetics
International Journal of Cosmetic Science, EarlyView.This review explores the physiological basis of tactile perception and critically examines classical and emerging sensory methods used in cosmetics, advocating for broader methodological integration and recognition of sensory analysis in the field. Abstract Sensory analysis is a cornerstone of cosmetic development, yet remains underrepresented in peer ...

Normal map recovery using bundle adjustment
IET Computer Vision, 2014 Although modern reconstruction methods have advanced considerably, their ability to retrieve fine details, small features of a surface is limited. Applying texture can be used to conceal lack of geometry to some extent, but it becomes apparent when ...

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

Self-Calibrating Deep Photometric Stereo Networks [PDF]
2019 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2019 This paper proposes an uncalibrated photometric stereo method for non-Lambertian scenes based on deep learning. Unlike previous approaches that heavily rely on assumptions of specific reflectances and light source distributions, our method is able to determine both shape and light directions of a scene with unknown arbitrary reflectances observed under
