Abstract:
1. A method for identifying a target object, the method comprising: determining, based on a first pre-determined set of criteria, one or more first order collections of pixels comprising a plurality of one-dimensional gradient runs in electronically acquired images of the target object; creating one or more second order collections of pixels from the one or more first order collections of pixels based on a second pre-determined set of criteria; using a decision tree to discover one or more primitives corresponding to the one or more second order collections of pixels, including identification of an anchor primitive, based on a third pre-determined set of criteria including known characteristics of the target object; and identifying the target object based on the one or more discovered primitives, wherein a primitive is a group of pixels that taken together comprise a single indivisible component of order that can be used to define a more complex shape and the anchor primitive is a first primitive ranked in a descending order.
