Unconventional TV Detection using Mobile Devices
TL;DR: In this paper, the authors exploit the context information available from the ubiquitous mobile devices to detect the presence of TVs and track the media being viewed, and present the feasibility of the proposed sensing technique using their implementation on Android phones with different realistic scenarios.

The Improvement of the Three Dimensional Douglas-Peucker Algorithm
Shi Qing Dou,Xiao Yu Zhang +1 more
TL;DR: The principle of the 3D D-P algorithm was introduced firstly, and the first base plane was artificially designated instead of the loop search in the tight method, this improvement makes the computational efficiency to improve dozens of times, but the result of generalization of 3D discrete point is very similar to the generalized result by the Tight method.

Automated monocular vision based system for picking textureless objects
TL;DR: An Autonomous Machine Vision system which grasps a textureless object from a clutter in a single plane, rearranges it for proper placement and then places it using vision using a unique vision-based pose estimation algorithm, collision free path planning and dynamic Change-Over algorithm for final placement.
Modeling surfaces from volume data using nonparallel contours
Cindy Grimm,Ross T. Sowell +1 more
TL;DR: VolumeViewer is developed, a novel interface for modeling surfaces from volume data by allowing the user to sketch contours on arbitrarily oriented cross-sections of the volume, and the algorithms necessary to support nonparallel contouring are designed.

Database and baseline system for detecting degraded traffic signs in urban environments
TL;DR: A baseline system for detecting and recognizing signs in this database, primarily employing color segmentation in the RGB color space, shape detection, and a number of problem specific heuristics proves quite robust to the degraded traffic signs of this collected database.

Computer representation of planar regions by their skeletons
John L. Pfaltz,Azriel Rosenfeld +1 more
TL;DR: Any region can be regarded as a union of maximal neighborhoods of its points, and can be specified by the centers and radii of these neighborhoods; this set is a sort of "skeleton" of the region.

The Application of Computation and Automatic Drawing Instruments to Structural Generalisation
TL;DR: An account of a series of experiments in computer generalisation, in which the outline of the Netherlands at 1:25 000 scale has been used to generate aseries of generalisations between 1:600 000 and 1:3 500 000.
