Project Description

In future smart cities, many decision processes in critical infrastructure and emergency management will be based on machine learning techniques. One particular application will be the processing of large datasets of visual images for defect assessment where the data is collected by a swarm of mobile sensing agents (e.g., UAVs). A critical requirement for the success of such assessment processes is the reliable detection, quantification, and localization of defective regions. Furthermore, in such applications, the real-time assessment is often critical so that the swarm can decide regarding the optimum strategy and corresponding actions for effective data collection in unknown. On the other hand, the reliability of the assessments requires data of good quality, since poor data may negatively affect the accuracy of classification and predictions, and consequently, may introduce additional costs and time overhead. The selected candidate will work on developing a framework for real-time, adaptive, and cost-effective collection of high-quality data for autonomous condition assessment of civil infrastructures. To this end, several technologies will be leveraged to devise effective and inexpensive solutions, including: deep neural networks; signal and image processing techniques; mobile image data acquisition agents (mobile phones, drones, robots); static sensor networks; 5G networks and edge computing; crowdsourcing.
