Research Topic Description, including Problem Statement:

Human and animal population monitoring is an important application area in civilian and military sectors. Remotely monitoring specific areas of interest or surveying large areas require automated processing and extraction of objects. Using this knowledge, repeated measurements over longer periods of time can be used to build an understanding of pattern-of-life of a group of areas of interest. With the ever-expanding dataset of many locations, reduction in knowledge expertise, and complexity of patters, such important tasks are becoming a challenge to determine. Though the current process of finding repeating patterns or relationships in the data is a manually and time intensive operation where experts in the field have the historical context to determine such patters, a need to develop such automated models is imperative. In addition, because the times between sample instances may vary considerably, a pattern-of-life model that incorporates this information in a meaningful way is central. In short, the purpose of this research project is to develop a pattern-of-life model of determining correlation between object detections over a set of multiple areas where population sampling is irregular.

Example Approaches:

This project is looking for novel pattern-of-life models that can of determine correlation between population-fluctuation of multiple class object detections over a set of multiple areas where population sampling is irregular. Such techniques that could be exploited are computer vision implemented with discrete-time models, Continuous-time Markov Chains (CTMC), or parametric approaches with time-evolving set of parameters. A successful project will develop a model with bespoke metrics to find patters between different population counts over multiple locations where population sampling is sporadic.

Relevance to the Intelligence Community:

Understanding and the correlating between object detection population fluctuations over multiple sites is important in determining the pattern-of-life of areas of interest and finding anomalies that might trigger further detailed analysis that might have been missed. Determining such correlation will allow the IC to provide national leaders important information and anomaly activity indicators to make relevant and educated future decisions of an area.
