PRESS: a novel framework of trajectory compression in road networks
TL;DR: Zhang et al. as discussed by the authors proposed a parallel road-network-based trajectory compression (PARALLELED ROAD-NATION-based Trajectory Compression) to compress trajectory data under road network constraints.
Journal ArticleDOI
Urban flow prediction from spatiotemporal data using machine learning: A survey
TL;DR: Wang et al. as mentioned in this paper introduced four main factors affecting urban flow, and partitioned the preparation process of multi-source spatiotemporal data related with urban flow into three groups: mobile phone data, taxi trajectories data, metro/bus swiping data, bike-sharing data.

Building roof modeling from airborne laser scanning data based on level set approach
KyoHyouk Kim,Jie Shan +1 more
TL;DR: A novel approach to building roof modeling, including roof plane segmentation and roof model reconstruction, from airborne laser scanning data is presented, which determines multiple roof segments at the same time, which leads to topological consistency among the segment boundaries.

Automatic fruit count on coffee branches using computer vision
TL;DR: A non-destructive method is proposed to count the number of fruits on a coffee branch by using information from digital images of a single side of the branch and its growing fruits, which offers useful information for them to plan agricultural work and obtain economic benefits from the correct administration of resources.

A 30+ Year AVHRR LAI and FAPAR Climate Data Record: Algorithm Description and Validation
TL;DR: This climate data record is based on a carefully calibrated and corrected land surface reflectance dataset to provide a high-quality, consistent time-series suitable for climate studies and is available in near real-time allowing use for monitoring purposes.

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.
