Data Encryption using Geometric Range

Robust Range Data Segmentation using Geometric Primitives for Robotic Applications

This paper presents a data-driven approach for segmenting range data to enable a humanoid robot to perform interactive domestic tasks. Range data is segmented into geometric primitives (planes, spheres, cylinders and cones), allowing the robot to recognize many simple objects. The algorithm calculates initial segments using depth discontinuities, creases and changes in surface type, with subseq...

Geometric Evaluation and Validation of Aerial and Satellite Data Using Sioux Falls Geometric Test Range

The U.S. Geological Survey (USGS) has developed the first of a series of geometric test ranges over Sioux Falls, South Dakota. The purposes of these test ranges are for evaluating, validating and characterizing high resolution satellite and aerial images. The Sioux Falls test range uses accurate and standardized high resolution aerial orthophotos as a reference dataset to compare and characteri...

Selective Encryption Algorithm for GIS Vector Map Using Geometric Objects

This paper presents the novel selective encryption algorithm for vector map protection for storage, transmission, distribution to authorized users. In proposed algorithm, we just select some values of polylines and polygons in DCT domain to encrypt by random algorithms and cryptography. Experimental results verified that proposed algorithm is effectively and security. Maps are changed whole aft...
