Human motion retrieval based on freehand sketch [PDF]

, 2014
In this paper, we present an integrated framework of human motion retrieval based on freehand sketch. With some simple rules, the user can acquire a desired motion by sketching several key postures.

Primary visual cortex activity along the apparent-motion trace reflects illusory perception [PDF]

, 2005
The illusion of apparent motion can be induced when visual stimuli are successively presented at different locations. It has been shown in previous studies that motion-sensitive regions in extrastriate cortex are relevant for the processing of apparent ...

Unsupervised Progressive Structure-from-Motion for Unordered Images

, 2012
A robust progressive structure from motion (PSFM) method is proposed for unordered images. Our method can reduce accumulative error efficiently during scene dense recovery and camera motion estimation.

Odometry-based structure from motion

, 2010
S.1112-1117Structure from motion refers to a technique to obtain 3D information from consecutive images taken with a moving monocular camera. In order to do this, the camera motion performed between two consecutive images needs to be known.

Generation of Virtual Ground Control Points Using a Binocular Camera

Drones
This paper presents a methodology for generating virtual ground control points (VGCPs) using a binocular camera mounted on a drone. We compare the measurements of the binocular and monocular cameras between the classical method and the proposed one. This

The Use of Gigapixel Photogrammetry for the Understanding of Landslide Processes in Alpine Terrain

Geosciences, 2019
The work in this paper illustrates an experimental application for geosciences by coupling new and low cost photogrammetric techniques: Gigapixel and Structure-from-Motion (SfM).

Recovering three-dimensional structure from motion with surface reconstruction

, 1995
This paper addresses the computational role that the construction of a complete surface representation may play in the recovery of 3-D structure from motion.

Affine and Projective Structure from Motion [PDF]

, 1992
We demonstrate the recovery of 3D structure from multiple images, without attempting to determine the motion between views. The structure is recovered up to a transformation by a 3D linear group — the affine and projective group.

Unaffected perceptual thresholds for biological and non-biological form-from-motion perception in autism spectrum conditions [PDF]

, 2010
Background: Perception of biological motion is linked to the action perception system in the human brain, abnormalities within which have been suggested to underlie impairments in social domains observed in autism spectrum conditions (ASC).
