Hough Transform for Opaque Circles Measured from Outside and Fuzzy Voting For and Against [chapter]

Leszek J. Chmielewski, Marcin Bator
2012 Lecture Notes in Computer Science  
Geometrical limitations on the voting process in the classical Hough transform resulting from that the detected objects are opaque to the applied means of measurement are considered.  ...  Departures from this rule are admitted, so fuzzy voting between positive and negative evidence for the object is considered.  ...  We wish to thank Krzysztof Stereńczak and Micha l Zasada from the Faculty of Forestry, Warsaw University of Life Sciences (SGGW), for valuable discussions and for providing the LIDAR data used in the experiments  ...

Advantages of Using Object-Specific Knowledge at an Early Processing Stage in the Detection of Trees in LIDAR Data [chapter]

Leszek J. Chmielewski, Marcin Bator, Marcin Olejniczak
2014 Lecture Notes in Computer Science  
In some imaging setups the following assumptions hold: the objects are opaque and viewed only from one point, their surface is continuous at least piecewise, and the occluding objects are small with respect  ...  This made it possible to design algorithms with some desired features: the segmentation based on sorting the data according to angle and the version of the object verification method using fuzzy voting  ...  Fig. 3 . 3 The layout and notations used in fuzzy voting for and against the circle s(C, R).

Display Methods for Gray-Scale, Voxel-Based Data Sets [chapter]

Victoria Interrante, William Oliver, Stephen Pizer, Henry Fuchs
1994 Three-dimensional Confocal Microscopy  
Due in part to the rapid, almost frantic, pace of developments in methods for rendering images from volume data, there has not yet emerged any widely accepted taxonomy for these methods.  ...  In addition, we touch on some of the major issues involved in creating high-quality images from volume data, including the problems of surface definition and object segmentation.  ...  Gary Smith, obtained with partial funding from NIH-CA24144.

Automatic reconstruction of textured 3D models

Benjamin Pitzer, Sören Kammel, Charles DuHadway, Jan Becker
2010 2010 IEEE International Conference on Robotics and Automation  
We also propose a calibration procedure for this system that determines the internal and external calibration which is necessary to transform data from one sensor into the coordinate system of another  ...  We demonstrate that this method is very suitable for the reconstruction of indoor environments. Finally, we present a solution to the reconstruction of texture maps from multiple scans.  ...  For example, the Generalized Hough transform [Hecker and Bolle, 1994] , geometric hashing [Wolfson and Rigoutsos, 1997] , and pose clustering [Stockman, 1987] quantize the transformation space into  ...

Towards Multi-modal Sclera and Iris Biometric Recognition with Adaptive Liveness Detection

Abhijit Das, University, My, Michael Blumenstein
2018
Security breaches due to misidentification of an individual pose one of the greatest threats and challenges for today's world. The use of biometrics can be quite promising in minimising this threat.  ...  In a multimodal biometric system, two or more biometric identifiers are fused by an information fusion technique, thereby providing robustness for changing in a greater range of environmental conditions  ...  These measures are based on transformed domain, geometrical relation and contrast measures. 3.  ...
