Hiearchy of Parts

Image feature extraction algorithm partially based on S. Fidler's article
Hierarchical Statistical Learning of Generic Parts of Object Structure. These features
can find application in wide field of tasks in image recognition and object detection.
This unsupervised algorithm builds hierarchical structure of complex edge
sequences upon simple pixel-wide edge features. Detection of these sequences
should be highly efficient due to its hierarchical structure.
