Straight lines have to be straight
We use the following fundamental property: a camera follows the pinhole model if and only if the projection of every line in space onto the camera is viewed in the transformed image as a line. Expand
A Variational Method for Scene Flow Estimation from Stereo Sequences
We propose to recover the scene flow by coupling the optical flow estimation in both cameras with dense stereo matching between the images, thus reducing the number of unknowns per image point. Expand
Dense Semi-rigid Scene Flow Estimation from RGBD Images
We propose a new scene flow approach that exploits the local and piecewise rigidity of real world scenes. Expand
A Non-Maxima Suppression Method for Edge Detection with Sub-Pixel Accuracy
In this article we present a two dimensional edge detector which gives the edge position in an image with a sub-pixel accuracy. The method presented here gives an excellent accuracy (the positionExpand
Automatic calibration and removal of distortion from scenes of structured environments
Most algorithms in 3D computer vision rely on the pinhole camera model because of its simplicity, whereas video optics, especially low-cost wide-angle lens, generate a lot of nonlinear distortionExpand
Symmetry Aware Evaluation of 3D Object Detection and Pose Estimation in Scenes of Many Parts in Bulk
We present automatic techniques to produce fully annotated RGBD data of many object instances in arbitrary poses, with which we produce a dataset of thousands of independent scenes composed of both real and synthetic images. Expand
Computing differential properties of 3-D shapes from stereoscopic images without 3-D models
We are considering the problem of recovering the three-dimensional geometry of a scene from binocular stereo disparity. Expand
From projective to Euclidean reconstruction
We use a stereo rig which is supposed to be weakly calibrated using a method such as the one described in Deriche et al. (1994) to make a Euclidean reconstruction of a whole object from uncalibrated cameras using the method proposed here. Expand
Hand Motion from 3D Point Trajectories and a Smooth Surface Model
A method is proposed to track the full hand motion from 3D point trajectories reconstructed using a stereoscopic set of cameras. Expand
Three-dimensional motion tracking of coronary arteries in biplane cineangiograms
A three-dimensional (3-D) method for tracking the coronary arteries through temporal sequence of biplane X-ray angiography images is presented. Expand
