Description

Research Topic Description, including Problem Statement:

The goal of this research is to develop scalable methods that leverage geotagged, ambient sound data to improve overhead imagery and video classification. Sound scene information can be an important component for cross-modal understanding of anthropogenic and environmental activity.  Recent advances in the fields of soundscape ecology and computational analysis of sound scenes have demonstrated new applications for recording and classifying ambient sounds and acoustic features. However, labeled and geolocated sound datasets can be expensive and challenging to obtain without field collection and/or in-situ instruments. The focus of this research is on approaches for scalable data collection and automated techniques that can be combined to develop foundational geospatial sound data, enrich point-of-interest (POI), and land use classifications with place-based sound representations and improve video event detection and summarization.

Example Approaches:

Research approaches may include one or more relevant areas of interest:

  • Methods that leverage existing (e.g., SoundNet, Google AudioSet) and new sources of massive natural sound data.

  • Methods for transferring existing knowledge of building and land use, such as OpenStreetMap labels and classifications from overhead imagery, to sound models that can be used to enrich new or sparsely-labeled POIs and image scenes.

  • Methods that incorporate or identify relationships between acoustic data and other types of geospatial feature data, such as sounds and temporal patterns related to specific points of interest, building usage, or land use.

  • Approaches for developing aggregate acoustic signatures and temporal sound patterns of places.

  • Methods that identify unique sound features of specific places or that match sound data from unknown locations to potential places of origin.

  • Data models and scalable architectures to efficiently collect, store, and geospatially analyze ambient sound data at multiple spatial scales.

  • Methods that address challenges associated with data variability and quality, such as differences in temporal length or sensor quality, without discarding information.
