چکیده

The edgelets produced by the Canny edge detector are first thresholded to reduce weak clutter. Beginning from an edgelet, we track along connected neighbours to get a list of edgelets. If one edgelet has more than two neighbours, we check all possible extensions of the curve, and segment the curves on a largest-first basis, breaking the others to form separate curves. This removes small spurs effectively.

3D model construction of induced polarization and resistivity data with quantifying uncertainties using geostatistical methods and drilling (Case study: Madan Bozorg, Iran)

Madan Bozorg is an active copper mine located in NE Iran, which is a part of the very wide copper mineralization zone named Miami-Sabzevar copper belt. The main goal of this research work is the 3D model construction of the induced polarization (IP) and resistivity (Rs) data with quantifying the uncertainties using geostatistical methods and drilling. Four profiles were designed and surveyed us...

Grouping uncertain oriented projective geometric entities with application to automatic building reconstruction

Grouping Uncertain Oriented Projective Geometric Entities with Application to Automatic Building Reconstruction The fully automatic reconstruction of 3d scenes from a set of 2d images has always been a key issue in photogrammetry and computer vision and has not been solved satisfactory so far. Most of the current approaches match features between the images based on radiometric cues followed by...

A Laminar Cortical Model for 3D Perception of Slanted and Curved Surfaces and of 2D Images: Developement, attention, and Bistability

A model of laminar visual cortical dynamics proposes how 3D boundary and surface representations of slanted and eurved 3D objeets and 2D images arise. The 3D boundary representations emerge from interactions between non-elassical horizontal receptive field interactions with intracortical and intercortical feedback circuits. Such non-classieal interactions contextually disambiguate classieal rec...

2D-To-3D Conversion of Images

The three-dimensional (3D) displays required the depth information which is unavailable in the conventional 2D content. This work presents a novel algorithm that automatically converts 2D images into 3D ones. The proposed algorithm first segments the image into object groups by choosing an effective grouping method. This is done with the help of the edge information. The grouping is based on th...

Target detection Bridge Modelling using Point Cloud Segmentation Obtained from Photogrameric UAV

In recent years, great efforts have been made to generate 3D models of urban structures in photogrammetry and remote sensing. 3D reconstruction of the bridge, as one of the most important urban structures in transportation systems, has been neglected because of its geometric and structural complexity. Due to the UAV technology development in spatial data acquisition, in this study, the point cl...
