Implementation of stereo correspondence algorithms for multi-baseline vision system
… the impact of varying camera baselines on correspondence and depth estimation. As the baseline increases the resolution of depth increases but finding correspondences is very tedious. On the other hand when cameras are placed close to each other and thereby reducing the baseline distance …

Geometric and Photometric Modeling of Three-Dimensional Scenes From Multiple Views
… of a homogeneous specular material, where stereo correspondence is almost impossible, we develop a method that extends the conventional shape from shading to multiple views and unknown reflectance. It is an iterative framework to solve for the 3D shape and parameterized photometric model. …

Wavelet Transforms for Stereo Imaging
Stereo vision is a means of obtaining three-dimensional information by considering the same scene from two different positions. Stereo correspondence has long been and will continue to be the active research topic in computer vision. The requirement of dense disparity map output is great demand …

Methodologies for visual correspondence
Visual correspondence is a key computer vision task that aims at identifying projections of the same 3D point into images taken either from different viewpoints or at different time instances. This task has been the subject of intense research activities in the last years in scenarios such as …

Broadband World Modeling and Scene Reconstruction
… process involves two main steps. The first is stereo correspondence using block matching algorithms with filtering to improve the quality of this matching process. The disparity maps are then transformed into 3D point clouds. These point clouds are filtered again before the registration process …

Local Bundling of Disparity Maps for Improved Dense 3D Visual Reconstruction
… presents a new method for improved resolution of stereoscopic 3D terrain mapping by local dense bundling of disparity maps. The Unmanned Systems Lab (USL) at Virginia Tech is designing an unmanned aerial vehicle (UAV) first-response system capable of 3D terrain mapping in the wake of a nuclear …

Automatic Positioning and Design of a Variable Baseline Stereo Boom
Conventional stereo vision systems rely on two spatially fixed cameras to gather depth information about a scene. The cameras typically have a fixed distance between them, known as the baseline. As the baseline increases, the estimated 3D information becomes more accurate, which makes it …

Methods for multi-spectral image fusion: identifying stable and repeatable information across the visible and infrared spectra
… modalities is approached using computational stereo methods; the focus is on the viewpoint alignment and correspondence search/matching stages of processing. Frequency domain analysis is performed using a method called phase congruency. An extensive investigation of this method is carried out …

OPTIMAL SUBSEQUENCE BIJECTION AND CLASSIFICATION OF IMBALANCED DATA SETS
… in many applications like shape alignment or stereo correspondence it is also desirable to have a one-to-one and onto correspondence (a bijection) between the remaining elements. To address the problem of noisy time series data we propose using an algorithm that determines the optimal …
