Deriving Spatio-Temporal Relations from Simple Data Structure
Data Structure Operation Query Object Spatial Temporal
2015/12/1
A spatiotemporal data model is incomplete without three components: classes, consistency constraints, and operators. Classes define the structure of the model, constraints enforce consistency in the m...
Dynamic Cartographic Representation of Spatio-Temporal Data
Spatio-temporal Database Spatio-temporal Change Pattern Dynamic symbol base
2015/12/1
As efforts grow to develop spatio-temporal database systems and temporal geographic information systems that are capable of conveying how geographic phenomena change, it is important to associate the ...
A FRAMEWORK FOR ONLINE SPATIO-TEMPORAL DATA VISUALIZATION BASED ON HTML5
Spatio-temporal data Web based visualization HTML5 WebSocket Canvas
2012/7/27
Web is entering a new phase – HTML5. New features of HTML5 should be studied for online spatio-temporal data visualization. In the proposed framework, spatio-temporal data is stored in the data server...
Several aspects of spatiotemporal databases have been explored in past decades, ranging from basic data structure to query processing and indexing. But today, operational temporal GIS does not exist. ...
modeling and visualizing spatio-temporal pattern of land cover change in pearl river delta region of china using multi-temporal imagery
Spatio-temporal pattern LUCC Change detection Pearl River Delta region urban growth mode
2009/4/11
Landuse and land cover change (LUCC) is regarded as a good indicator that represents the impacts of human activities on the earth’s environment. When the large collection of multi-temporal satellite i...
Dynamic Background Modeling and Subtraction Using Spatio-Temporal Local Binary Patterns
Dynamic Background Modeling Subtraction Spatio-Temporal Local Binary Patterns
2008/12/31
Traditional background modeling and subtraction methods have a strong assumption that the scenes are of static structures with limited perturbation. These methods will perform
poorly in dynamic scene...
A Spatio-temporal Auto-regressive Model for Frame Rate up Conversion
Spatio-temporal Auto-regressive Model Frame Rate up Conversion
2008/12/31
This paper proposes a spatio-temporal auto regressive (STAR) model for frame rate upconversion. In the STAR model, each pixel in the interpolated frame is approximated
as the weighted combination of ...
A SPATIO-TEMPORAL AUTOREGRESSIVE FRAME RATE UP CONVERSION SCHEME
SPATIO-TEMPORAL AUTOREGRESSIVE FRAME RATE P CONVERSION SCHEME
2007/12/31
A spatio-temporal autoregressive model is proposed in this paper to address the problem of frame rate up conversion. Every pixel in a skipped frame is generated as a linear
combination of pixel value...
Semantic Object Segmentation by a Spatio-temporal MRF Model
Semantic Object Segmentation Spatio-temporal MRF Model
2004/12/31
In this paper, a region-based spatio-temporal Markov random field (STMRF) model is proposed to segment
moving objects semantically. The STMRF model combines segmentation results of four successive fr...
