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 ...
Analysis of Temporal Noise in CMOS APS
emporal noise subthreshold operation reset noise shot noise CMOS APS image sensor
2015/8/17
Temporal noise sets a fundamental limit on image sensor performance, especially under low illumination and in video applications. In a CCD image sensor, temporal noise is well studied and characterize...
Analysis of Temporal Noise in CMOS Photodiode Active Pixel Sensor
CMOS APS image sensor reset noise shot noise subthreshold operation temporal noise time-domain noise analysis
2015/8/12
Temporal noise sets the fundamental limit on image sensor performance, especially under low illumination and in video applications. In a CCD image sensor, temporal noise is primarily due to the photod...
Pattern Recognition by Hierarchical Temporal Memory
Pattern Recognition Hierarchical Temporal Memory
2015/7/21
Hierarchical Temporal Memory (HTM) is still largely unknown by the pattern recognition community and only a few studies have been published in the scientific literature. This paper reviews HTM archite...
An Improved Multi-Temporal Insar Method for Increasing Spatial Resolution of Surface Deformation Measurements
Multi-temporal InSAR hierarchical analysis spatial resolution Pearson correlation coefficient deformation extraction
2014/4/22
The multi-temporal interferometric synthetic aperture radar (InSAR) technology has proven very useful in extracting surface deformation with time series of SAR images over a study area. To increase sp...

Change detection airborne laser scanning logistic regression
2014/6/5
Multitemporal LiDAR data provide means for mapping structural changes in forest canopies. We demonstrate the use of area-based estimation method for snow damage assessment. Change features of bi-tempo...
A FRAMEWORK FOR ONLINE SPATIO-TEMPORAL DATA VISUALIZATION BASED ON HTML5
Spatio-temporal data Web based visualization HTML5 WebSocket Canvas
2014/4/25
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. ...
Robust Copy Detection by Mining Temporal Self-Similarities
Robust Copy Detection Mining Temporal Self-Similarities
2010/12/20
This paper introduces a Self-Similarity Matrix (SSM) based video copy detection scheme and a Visual Character-String (VCS) descriptor for SSM matching. SSM, which exploits the spatial and
temporal in...
