Detailed Description

Cornerwise geometric histrograms.

Cornerwise geometric histrograms encode edge strings. can be used for feature recognition purposes. developed for learning of environments , they have good invariance to scale ( to viewing position ). They *can* have good invariance to feature rotation on the image plane but the current code doesn't have this. Capacity of the representation is about 250,000 with the default parameters. For more info consult this PhD thesis.
