From Real-Time Sensor Data Streams to Continuous Field Data Models: Formal Foundations and Computational Challenges
From Real-Time Sensor Data Streams to Continuous Field Data Models: Formal Foundations and Computational Challenges
The goal of this project is to develop a computational framework for spatio-temporal fields based on large numbers of high-rate real-time sensor data streams.
Segmentation of Birds in Video Data Streams
Segmentation of Birds in Video Data Streams
The goal of this project is to develop technology to detect bird and bat behaviors around terrestrial and offshore wind farms.
Non-Visual access to Geographic Information Using Vibro-audio Displays
Non-Visual access to Geographic Information Using Vibro-audio Displays
The goal of this project is to develop and evaluate a highly intuitive tool for members of the blind and low-vision community that would address the longstanding challenge of affording low-cost and effective access to graphical materials.
Perception of Scene Layout by Machines and Visually Impaired Users
Perception of Scene Layout by Machines and Visually Impaired Users
The project investigates computational methods for object detection, spatial scene construction, and natural language spatial descriptions derived from real-time visual images to describe prototypical indoor spaces (e.g., rooms, offices, etc).
Information Integration and Human Interaction for Indoor and Outdoor Spaces
Information Integration and Human Interaction for Indoor and Outdoor Spaces
The goal of this research project is to provide a framework model that integrates existing models of indoor and outdoor space, and to use this model to develop an interactive platform for navigation in mixed indoor and outdoor spaces.
Theory of Topological Relations for Compound Spatial Objects
Theory of Topological Relations for Compound Spatial Objects
The core activity is the study of the interplay between topological spatial relations with holed regions and topological spatial relations with separated regions to address the potentially complex configurations that feature both holes and separations.
Monitoring Dynamic Spatial Fields Using Responsive Geosensor Networks
Monitoring Dynamic Spatial Fields Using Responsive Geosensor Networks
The goal of this project is to provide efficient ways for sensor networks to monitor such fields, and to report significant changes in them.
IGERT Sensor Science Engineering and Informatics
IGERT Sensor Science Engineering and Informatics
The Sensor Science Engineering and Informatics (SSEI) IGERT program provides PhD training in the multidisciplinary area of sensor systems: ranging from the science and engineering of new materials and sensing mechanisms to the interpretation of sensor data.
Maine Cancer GIS
Maine Cancer GIS
This project developed a geographic database to support research on the relationships of cancer and the environment in Maine.
Information Integration Through Events
Information Integration Through Events
Environmental data collections are increasing and there is a growing interest in integrating such data to investigate ecological phenomena and their interactions.
Data Management in Ad-Hoc Geosensor Networks
Data Management in Ad-Hoc Geosensor Networks
This project explores data management methods for geosensor networks. An important task of such geosensor networks is to collect, analyze and estimate information about continuous phenomena under observation such as temperature or pollutants.
