A KERNEL-BASED SIMILARITY MEASURING FOR CHANGE DETECTION IN REMOTE SENSING IMAGES
Change detection kernel function similarity measure probability density
2016/11/24
This paper presents a kernel-based approach for the change detection of remote sensing images. It detects change by comparing the probability density (PD), expressed as kernel functions, of the featur...

The author analyzes current methods of 3D documentation of historical tunnels in Skorkov village, which lies at the Jizera river, approximately 30 km away from Prague. The area is known as a former mi...
A FAST METHOD FOR MEASURING THE SIMILARITY BETWEEN 3D MODEL AND 3D POINT CLOUD
Partial Similarity 3D Point Cloud 3D Mesh Laser Scanning 3D Object Retrieval Weighted Hausdorff Distance
2016/7/5
This paper proposes a fast method for measuring the partial Similarity between 3D Model and 3D point Cloud (SimMC). It is crucial to measure SimMC for many point cloud-related applications such as 3D ...
MEASURING A DYNAMIC AND FLOODING RIVER SURFACE BY CLOSE RANGE DIGITAL PHOTOGRAMMETRY
Close Range Photogrammetry Digital Surface Models Digital Photogrammetry Feature Extraction Hydrology, Floods Point Cloud
2015/12/26
Current state of the art computational fluid dynamics (CFD) and in particular, river flow modelling, require accurate estimation of the “free surface” in order to accurately predict the three dimensio...

Component calibration Terrestrial laser scanner Robot tacheometer
2015/12/17
This paper deals with component calibration of a terrestrial laser scanner Faro LS880 HE80. The calibration is based on relative
distance measurements and is focused on the distance measuring compone...
Measurement and 3D Modelling of an Ancient Measuring Device: Nippur Cubit Rod
cultural heritage close-range photogrammetry structured light system
2015/12/16
For all think surveys of archaeological sites it is of utmost importance to recognize the fact that (nearly) all ancient buildings and
towns are established according to an obviously normed set of pr...
Broken-Ray Videometric Method and System for Measuring the Three-Dimensional Position and Pose of the Non-Intervisible Object
Close Range Photogrammetry Deformation Digital photogrammetry
2015/12/14
The traditional videometrics technique is usually adopted to measure the relative position and pose between the intervisible objects,
and is invalid for measuring the three-dimensional position, pose...
Verification of the Accuracy of a Real-time Optical 3D-Measuring System on Production Line
Accuracy Verification Real-time Optical Measurement Industrial Production
2015/12/14
Verifying the accuracy of a real-time optical 3D-measuring system on production line has been problematic in many senses. Reasons
for this arise from the production line environment as well as the bu...
MEASURING THE QUALTITY OF SAMPLES IN THE SUPERVISED CLASSIFCATION OF REOTELY SENSED IMAGERY
Supervised classification measuring the sample quality rough set
2015/9/28
In the supervised classification process of remotely sensed imagery, the quantity of samples is one of the important factors affecting the accuracy of the image classification as well as the keys used...
A METHOD FOR MEASURING THE PERMITTIVITY OF ARTIFICIAL FROZEN SOIL USING NETWORK ANALYZER
Frozen Soil Permittivity Network Analyzer
2015/9/8
Frozen soil is best observed by microwave remote sensing due to the big difference of the permittivity comparing with unfrozen soil.
The dielectric property of frozen soil has much relation with its ...
