A New Approach for Extraction of Information from Unoverlapped Photographed Area of a Stereo-pair
"... Abstract: Most of conventional photogrammetric tasks in reconstructing the 3D object space have been mainly relying on distinct discrete points, to be totally associated with all underlying operations, just only in the overlapping region between photos. Nowadays, with the advent of digital photogram ..."
AUTOMATIC 3D EXTRACTION OF RECTANGULAR ROADMARKS WITH CENTIMETER ACCURACY FROM STEREO-PAIRS OF A GROUND-BASED MOBILE MAPPING SYSTEM
"... The present paper is an extension of a previous work presented in (Soheilian et al., 2006a) in which an automatic algorithm of zebracrossing reconstruction from stereo-pairs of a mobile mapping system was proposed. The method has been adapted to reconstruct different types of rectangular roadmarks. ..."

"... Software development frameworks are considered the engine that leads the development activities within software development organizations, so the main interest in this research is establishing a framework to effectively lead the development activities to enhance the software quality. The proposed fr ..."

framework relates each development phase with its available artifacts, software metrics can be extracted from its artifacts and relates the test practices and QA best practices during the SDLC. It provides an organized approach to handle miscommunication and poor team management that usually lead to team
3D ROAD EXTRACTION USING A STEREO PAIR OF AERIAL IMAGES
"... Road extraction from aerial and satellite imagery is of fundamental importance in the context of spatial data capturing and updating for GIS (Geographic Information System) applications. This article proposes a semiautomatic methodology for 3D road extraction from digital images. The dynamic program ..."

, this paper presents details of our stereo-based approach involving a stereo pair of aerial images. In order to initialise the extraction procedure, a few seed points are necessary to be supplied in the object-space to sparsely and coarsely describe the roads. We visually identify these points on the stereo
3-D Scene Data Recovery using Omnidirectional Multibaseline Stereo
, 1995
"... A traditional approach to extracting geometric information from a large scene is to compute multiple 3-D depth maps from stereo pairs or direct range finders, and then to merge the 3-D data This is not only computationally intensive, but the resulting merged depth maps may be subject to merging erro ..."

Obstacle Detection and Alignment Using an Stereo Camera Pair
"... Abstract — An autonomous mobile robot must face the correspondence or data association problem in order to carry out tasks like place recognition or unknown environment mapping. In order to put into correspondence two maps, most correspondence methods first extract descriptors of salient features fr ..."

obstacle maps without searching explicit matches between features. The maps are obtained from a stereo pair. Then, we use a bag of features approach to identify putative corresponding maps followed by a Gauss-Newton algorithm to find the transformation that relates both maps. The proposed method
Author(s): Depth estimation for stereo image pairs
"... Philips has developed a multi-view autostereoscopic 3D television which is capable of displaying video in real 3D without the use of external glasses or any other devices. Creating 3D content for these screens is difficult because they require not only the video itself but also the depth map as inpu ..."

as input. Depth maps are computed from a multi-view recording of the video sequence. To extract the depth map we have to solve the so called stereo correspondence problem. We developed a model, which with the help of some additional human input, can solve it reasonably well. We started by casting

Real-Time Vehicle Ego-Motion Using Stereo Pairs and Particle Filters
"... Abstract. This paper presents a direct and stochastic technique for real time estimation of on board camera position and orientation—the ego-motion problem. An on board stereo vision system is used. Unlike existing works, which rely on feature extraction either in the image do-main or in 3D space, o ..."

A SYSTEM FOR A TOTAL MATCHING OF STEREO PAIRS OF IMAGES
, 1981
"... A system which provides a total matching of a stereo pair of images is described: to every point in the first image a corresponding point in the second image is assigned. The processing consists of determining a limited number of matching candidates for each point in the first image and ordering the ..."
