Geometric feature learning of two sub-features which can be primitive features or compound features. There are two type of boolean features: conjunctive feature whose value is the product of two sub-features and disjunctive features whose value is the maximum of the two sub-features. Feature space was firstly considered in computer vision area by Segen. He used multilevel graph to represent the geometric relations of local features. There are many learning algorithms which can be applied to learn to find distinctive features of objects in an image. Learning can be incremental, meaning that the object classes can be added at any time. 1.Acquire a
