Measurement of Rock Joint Surfaces by Using Smartphone Structure from Motion (SfM) Photogrammetry
Sensors, 2021 The measurement of rock joint surfaces is essential for the estimation of the shear strength of the rock discontinuities in rock engineering. Commonly used techniques for the acquisition of the morphology of the surfaces, such as profilometers and laser ...

Interaction of perceptual grouping and crossmodal temporal capture in tactile apparent-motion [PDF]
, 2011 Previous studies have shown that in tasks requiring participants to report the direction of apparent motion, task-irrelevant mono-beeps can "capture'' visual motion perception when the beeps occur temporally close to the visual stimuli. However, the
