Ecological Monitoring Paramuricea clavata Multi-view stereo survey Underwater 3D Measurements
2018/6/4
This study presents a practical method to estimate dimensions of Paramuricea clavata colonies using generic photographic datasets collected across wide areas. Paramuricea clavata is a non-rigid, tree-...
REPRESENTING WITH LIGHT. VIDEO PROJECTION MAPPING FOR CULTURAL HERITAGE
video projection mapping cultural heritage laser scanning photogrammetry geoinformatics technologies architecture
2018/6/4
In this paper, we describe a cross-disciplinary process that uses photogrammetric surveys as a precise basis for video projection mapping techniques. Beginning with a solid basis that uses geoinformat...
MULTIPLE TLS POINT CLOUD REGISTRATION BASED ON POINT PROJECTION IMAGES
Terrestrial Laser Scanning Point Clouds Registration Point Projection Image Scan Graph Iterative Closest Point
2018/6/5
In this paper, an efficient and robust registration method of multiple point clouds is proposed. In our research, we assume that point clouds are acquired by Terrestrial Laser Scanning (TLS) systems, ...
INFRARED CEPHALIC-VEIN TO ASSIST BLOOD EXTRACTION TASKS: AUTOMATIC PROJECTION AND RECOGNITION
infrared thermography projector pattern recognition cephalic vein thermal map
2017/6/19
Thermal infrared band is not commonly used in photogrammetric and computer vision algorithms, mainly due to the low spatial resolution of this type of imagery. However, this band captures sub-superfic...
ENHANCEMENT OF STEREO IMAGERY BY ARTIFICIAL TEXTURE PROJECTION GENERATED USING A LIDAR
stereo LIDAR pattern projection structured light texture Gotcha
2016/11/11
Passive stereo imaging is capable of producing dense 3D data, but image matching algorithms generally perform poorly on images with large regions of homogenous texture due to ambiguous match costs. St...
Projection Merging: Reducing Redundancies in Inclusion Constraint Graphs
Projection Merging Reducing Redundancies Inclusion Constraint Graphs
2016/5/24
Inclusion-based program analyses are implemented by adding new edges to directed graphs. In most analyses, there are many di erent ways to add a transitive edge between two nodes, namely through each ...

Mercator conformal polar stereographic projection map projection Laplace's equation
2016/1/25
This paper is opening a new methodology in conformal transverse Projection for Gauss or ''Mercator'', and Conformal Russell stereographic projection. We know that Map Projection is using new method " ...
Trinary-Projection Trees for Approximate Nearest Neighbor Search
Approximate nearest neighbor search KD trees trinary-projection trees
2016/1/23
We address the problem of approximate nearest neighbor (ANN) search for visual descriptor indexing. Most spatial partition trees, such as KD trees, VP trees and so on, follow the hierarchical binary s...
FULLY CONSTRAINED OBLIQUE PROJECTION APPROACH TO MIXED PIXEL LINEAR UNMIXING
Hyperspectral Multispectral Sub-pixel classification Processing Recognition Detection Image
2015/12/31
Mixed pixels, which are inevitable in remote sensing images, often result in a lot of limitations in their applications. A novel approach for mixed pixel's fully constrained unmixing, Fully Constraine...
