33. We now have pixel pointing to better than one degree, are working on calibration and on-board degree, are working on calibration and on-board cloud detection using stars…. cloud detection using stars…. Image of the Big Dipper obtained by averaging one hour of star frames from the NORSTAR Gillam ASI. Pointing for pixels determined by minimizing the area of celestial objects in transformed co-added images. The transformation utilizes a matrix that is based on parameters that reflect the location, UT, imager orientation (pitch, yaw, etc), and details of the optics. All parameters can be determined directly from the data, provided that celestial objects are visible in the data. This is incredibly efficient, making the tasks at hand easily manageable, rather than virtually impossible.

34. Machine Vision – Content Based Image Retrieval We are exploring automatic classification of images, rapid retrieval of images from large datasets, and determination of motion of auroral forms, all using sophisticated machine vision techniques. This classification and CBIR exercise reduces each image to a 48 element feature vector.

35. A classification of 300000 CANOPUS Gillam ASI images yielded these magnetic local time occurrence distributions for arcs, patches and omega bands. This took about 6 hours on a 1.5 GHz pentium. An equivalent manual survey, which yielded the same results, took 4 months of dedicated effort by a student (who miraculously stayed in the field!). This figure from Syrjäsuo and Donovan [Ann. Geophys., in review].
