Introduction

AND-OR Template (AOT) is a probabilistic image model for object recognition. It has the following characteristics:

AND-OR Template for Egret
(automatically learned)
Detection of object, parts and primitives

Source code: training, detection.

More examples and comparison with latent SVM.
