Ordered shape contexts

WebHowever, the original shape contexts do not satisfy rotation invariance. The histograms of ships of the same type, at different azimuth angles, are vastly different. To enable the feature suitable for recognizing ships with different azimuths, we utilize the extracted principal axis of the ship as the reference angle for shape context.
