Calculating Stereo Pairs - Paul Bourke
Calculating Stereo Pairs Written by Paul Bourke July 1999 Introduction. The following discusses computer based generation of stereo pairs as used to create a perception of depth. Such depth perception can be useful in many fields, for example, scientific visualisation, entertainment, games, appreciation of architectural spaces, etc. Depth cues
 1D DIRECTIONAL DCT-BASED STEREO RESIDUAL COMPRESSION
Fig. 1: (a) Right view and (b) absolute residual the ‘Room’ stereo pair, the residual image is scaled by 8 for visualization (w= 8). to derive a model that could account for all these parameters.
Combined 2D and 3D tracking of surgical instruments for ...
Methods. Our method assumes that we have the 3D pose of the instrument in the first frame which we use to initialize a 2D bounding box (u ′, v ′, w, h) (see Fig. 1) around the instrument head where (u ′, v ′) is the pixel coordinates of top left corner of the bounding box which has width w and height h.We define the 2D detection problem as the estimation of the parameters λ 2D = (u, v ......
Changing Perspective in Stereoscopic Images
uses a discontinuous warping technique for 2D to 3D conversion, computing a projection from a new viewpoint. Their main goal is synthesis of a proper stereo image pair from an input 2D image and user input sketches, while our input is a stereo image pair, and we handle the problem of changing the stereo perspective in a general sense. [26 ......

The work [ ] proposes methods that perform 3D bounding box detection from 2D images. We extend a state-of-the-art model, namely the Deformable Parts Model (DPM) from Felzenszwalb et al., to a full 3D object model. The DPM is a mixture of star based CRF models that include deformation and appearance terms. We propose a CRF that models an object ......
STEREO PANORAMAS: PROBLEMS AND SOLUTIONS
KEY WORDS: 3D View, Stereo Bar, Stereo Model, Stereo Panorama ABSTRACT: Recent years have seen an increasing interest in the use of panoramic models to document architectural and archeological sites. A stereo-panorama is a new extension to a panoramic model which improves the model by adding the depth dimension to the simple...
Why is Occlusion in Augmented Reality So Hard? | Hacker Noon
The next step is to take the 2D depth image and turn it into a 3D point cloud model where each pixel in the depth image gets a 3D position relative to the camera. Next, all the camera relative point clouds are fused with an estimate of camera motion to create a 3D point cloud map of the world around the sensor.

Evolving Photogrammetry from Single-Pair Stereo to Multi ...
Stereophotogrammetry is a technique which mimics the stereo view of human eyes by restoring the 3D positions and orientations of an overlapping image pair. With the filtering of anaglyph red-cyan glasses, 3D glasses, or 3D screens, it allows us to see only one corresponding image out of a two-image pair for each eye, which lets […]...
A New Perspective on Viewing - CodeProject
Nearly all 3D programs use normal or right prisms and frustums where the axis is normal to the rectangular cross section, and so tsx and tsy are both zero. Correct stereo viewing requires non-zero tsx and tsy values, as will be shown later. The use of ZNear and ZFar, instead of a HalfDepth value, disassociates the width and height values from the placement of the near and far clipping planes.
