Efficient spatio-temporal event processing with STARK
For Big Data processing, Apache Spark has been widely accepted. However, when dealing with events or any other spatio-temporal data sets, Spark becomes very inefficient as it does not include any spatial or temporal data types and operators. In this paper we demonstrate our STARK project that adds the required data types and operators, such as spatio-temporal filter and join with various predic...
متن کاملContinuous Query Processing on Spatio-Temporal Data Streams
This thesis addresses important challenges in the areas of streaming and spatio-temporal databases. It focuses on continuous querying of spatio-temporal environments characterized by (1) a large number of moving and stationary objects and queries; (2) need for near real-time results; (3) limited memory and cpu resources; and (4) different accuracy requirements. The first part of the thesis stud...
متن کاملEfficient spatio-temporal decomposition for perceptual processing of video sequences
This paper presents a vision model for moving pictures. The model is an extension of a normalization model by T eo and Heeger. It accounts for normalization of the cortical receptive eld responses and inter-channel masking. The model is compared with a simpler vision model for video by presenting results on quality assessment of MPEG compressed video.

متن کاملEfficient Processing of Distributed Iceberg Semi-joins
The Iceberg SemiJoin (ISJ) of two datasets R and S returns the tuples in R which join with at least k tuples of S. The ISJ operator is essential in many practical applications including OLAP, Data Mining and Information Retrieval. In this paper we consider the distributed evaluation of Iceberg SemiJoins, where R and S reside on remote servers. We developed an efficient algorithm which employs B...
