Abstract

In this work we present our first results on the ambitious task of providing region-based querying capabilities to our existing Solar Dynamics Observatory (SDO) content-based image-retrieval (CBIR) system. By taking advantage of precomputed image descriptors, we calculate region-based histogram signatures for our training set of previously identified solar events. With these signatures we then explore the possibility of retrieving new similar solar events solely based on these scale and rotation invariant signatures. In this work we present our proposed methodology, initial retrieval results, verification and validation mechanisms, and propose future work with possible applications for other fields in astronomy.
