چکیده

It is often essential to create datasets with foreseeable characteristics. For the design and testing of advanced spatiotemporal pattern mining algorithms, adaptable and large datasets are needed. In this paper, we present a synthetic dataset generator, ERMO-DG, that is intended for creating spatiotemporal patterns. Generated datasets consist of spatiotemporal object instances of different feature types, where these instances are represented by spatial regions evolving over time. The generator allows researchers to systematically create spatiotemporal datasets with predictable characteristics such as number of patterns, cardinality of patterns, velocity, acceleration, lifetime and spatial areas of instances.

Evolving Region Moving Object Random Dataset Generator

Large-scale spatio-temporal data is crucial for testing the spatio-temporal pattern mining algorithms. In this paper we present a data set generator that can generate moving spatio-temporal instances, with evolving regions. The characteristics of data generated can be configured with parameters given to program and those parameters allow users to test the performance of spatio-temporal mining a...

A Framework for Generating Network-Based Moving Objects

Benchmarking spatiotemporal database systems requires the definition of suitable datasets simulating the typical behavior of moving objects. Previous approaches for generating spatiotemporal data do not consider that moving objects often follow a given network. Therefore, benchmarks require datasets consisting of such “network-based” moving objects. In this paper, the most important properties ...

The Generation of XML-Based Datasets for Moving Object Database

Datasets are the basis of the database benchmarks. They are very important to researches on database theories and applications. Datasets of the moving object database benchmarks record the spatial and temporal information of the moving objects. Based on the XML-based moving object data model, the algorithms generating moving object datasets are designed in this paper. The object number, object ...

Moving Object Localization Using Optical Flow for Pedestrian Detection from a Moving Vehicle

This paper presents a pedestrian detection method from a moving vehicle using optical flows and histogram of oriented gradients (HOG). A moving object is extracted from the relative motion by segmenting the region representing the same optical flows after compensating the egomotion of the camera. To obtain the optical flow, two consecutive images are divided into grid cells 14 × 14 pixels; then...

On the Generation of Time-Evolving Regional Data

Benchmarking of spatio-temporal databases is an issue of growing importance. In case large real data sets are not available, benchmarking requires the generation of arti®cial data sets following the real-world behavior of spatial objects that change their locations, shapes and sizes over time. Only a few innovative papers have recently addressed the topic of spatio-temporal data generators. How...
