Stereo-photometric techniques for scanning micrometer scale
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.

Rotatable Lens‐Based 3D Reconstruction Method for Monocular Vision Systems
Accurate 3D reconstruction in confined environments remains challenging because conventional vision‐based measurement systems are difficult to maintain compactness without sacrificing accuracy. Here, the authors develop a rotatable lens‐based monocular vision system, which is the first time using the refraction of the light induced by a rotating wedge ...

Mastcam‐Z Spectrophotometric Properties of Materials at the Van Zyl Overlook, Jezero Crater
Abstract During Sols 63–65 of Mars 2020, Mastcam‐Z multispectral (442–1022 nm) images were acquired at Van Zyl Overlook (VZO), spanning phase angles from ∼0° to 150°, to model photometric parameters for seven surface units. These units included rocks, soils, regolith, and rover tracks near the Jezero landing site.

Normal map recovery using bundle adjustment
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 ...

A Robust Visual Inertial Odometry SLAM Considering Robot Self Dynamics
ABSTRACT In this paper, to deal with the dynamic SLAM problem, we investigate feature tracking and IMU preintegration in visual‐inertial odometry (VIO) and design a robust SLAM framework that explicitly considers robot self‐dynamics. We propose a self‐dynamics and IMU‐aided feature tracker to predict initial optical flow and an iterative refinement ...

The hidden science of haptics: A pedagogical review of tactile evaluation in cosmetics
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 ...

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

ABSTRACT Spontaneous pupil fluctuations (SPFs) during rest provide a non‐invasive, low‐cost index of central arousal dynamics, independent of cognitive task demands. These features position SPFs as promising markers for baseline neurophysiological activity in both basic and translational research. This review synthesizes current evidence on the resting‐
