Geosciences, 2023 We assess the accuracy of Structure-from-Motion/Multiview stereo (SM) terrain models acquired ad hoc or without high-resolution ground control to analyze their usage as a base for inexpensive 3D bedrock geologic mapping.

Analysis of Changes in Forest Structure using Point Clouds from Historical Aerial Photographs
Remote Sensing, 2019 Dynamic changes in land use, many of which are related to land abandonment, are taking place in many regions of the world. As a result, forest vegetation appears, which in part is a consequence of planned afforestation programs and in part has the ...

Geosciences, 2020 The coastal system, with its physical chemical and biological components, is the place where the lithosphere, atmosphere and hydrosphere intersect and interact, and in which human activity has a considerable impact on the balance of the whole ecosystem ...

Track-Before-Detect Framework-Based Vehicle Monocular Vision Sensors
Sensors, 2019 This paper proposes a Track-before-Detect framework for a multibody motion segmentation (named TbD-SfM). Our contribution relies on a tightly coupled tracking before detection strategy intended to reduce the complexity of existing Multibody Structure ...

Structure from stereo and motion [PDF]
Journal of the Optical Society of America A, 1985 Stereopsis and motion parallax are two methods for recovering three-dimensional (3D) shapes. Theoretical analyses of each method show that neither alone can recover rigid 3D shapes correctly unless other information, such as perspective and vertical disparity, is included.

Interpolation in structure from motion [PDF]
Perception & Psychophysics, 1992 We investigated surface interpolation in displays of structure from motion (SFM). To do so, we introduced a new method for measuring surface perception in dynamic displays--the SFM probe. An SFM probe is a dot that moves rigidly with the dots on a simulated surface, and whose distance from that surface can be adjusted with a joystick or similar control.

Dynamic dot displays reveal material motion network in the human brain
NeuroImage, 2021 There is growing research interest in the neural mechanisms underlying the recognition of material categories and properties. This research field, however, is relatively more recent and limited compared to investigations of the neural mechanisms ...

The interpretation of structure from motion [PDF]
Proceedings of the Royal Society of London. Series B. Biological Sciences, 1979 Abstract The interpretation of structure from motion is examined from a computional point of view. The question addressed is how the three dimensional structure and motion of objects can be inferred from the two dimensional transformations of their projected images when no three dimensional information is conveyed by the individual ...

Structure and motion from silhouettes [PDF]
Proceedings Eighth IEEE International Conference on Computer Vision. ICCV 2001, 2002 This paper addresses the problem of recovering structure and motion from silhouettes. Silhouettes are projections of contour generators which are viewpoint dependent, and hence do not readily provide point correspondences for exploitation in motion estimation.
