 Piecewise Rigid Scene Flow - cv-foundation.org
Estimating dense 3D scene flow from stereo sequences remains a challenging task, despite much progress in both classical disparity and 2D optical flow estimation. To over-come the limitations of existing techniques, we introduce a novel model that represents the dynamic 3D scene by a collection of planar, rigidly moving, local segments. Scene...
Appearance-Based Virtual View Generation of Temporally ...
4.2 Correspondence from 3D model The 3D shape model of the object is used to compute correspondences between any pair of views. Figure 7 shows the scheme for making correspondences in accordance with the 3D shape model. For a point in view 1, the intersection of the pixel ray with the surface of the 3D model is computed. The 3D position of 5...
Stereo image quality assessment using visual attention and ...
Stereo image quality prediction is useful to reconstruct the right view, if it is absent, since the left view shares a lot on common or similar information with its right view [25] in the depth image based rendering (DIBR) [26].
Consistent Stereo Image Editing - CityU CS
Stereo Images Editing, Depth Mapping, Multi-label Optimization 1. INTRODUCTION With the popularity of stereo (or 3D) videos, techniques for pro-ducing and editing of stereo media are attracting a lot of research attention in recent years. In general, a stereo image contains two regular 2D images, which are captured from the same scene at the...
Occlusion-aware Depth Estimation Using Light-field Cameras
Standard stereo image pairs (nor general multi-view stereo configurations) do not directly satisfy the model. We use the modified photo-consistency condition, and the means/variances in the two regions, to estimate initial occlusion-aware depth (Sec.4). We also compute a predic-tor for the occlusion boundaries, that can be used as an input...

A Global 3D Map-Building Approach Using Stereo Vision
3D images. In [4][1], a range scanner is combined with a single camera through fusing the results of 2D and 3D matching and planar segmentation processes, and a high-level planning system obtains the best next view for acquiring the model of the environment. In this paper we focus on a third group of approaches that only use stereo cameras as ......
