Abstract

New image data mining mechanisms that enable content-based retrieval of images of interest from a large collection of satellite data of the Earth's aurorae are described. The mechanisms enable mining for wide aurorae, aurorae with large ovals, standard aurorae, and theta aurorae. Shape characteristics of these classes of aurorae are exploited by the mining mechanisms. Experimental results that benchmark the accuracy of the mechanisms are also presented.
