Abstract
Described is a pattern matching system for matching a test image with a 3D template. The system is initiated by generating a library of templates (each individual template is a three-dimensional array, with each pixel in the array representing a value at a particular x, y, and z coordinate). Each column of pixels along one axis (e.g., z) is converted into a neural input. Each neural input is fed through a neural network to establish a delayed connection between each neural input and output neuron and to generate a template neural network. Separately, a test image is converted into neural inputs. The neural inputs of the test image are input the template neural network to generate output neurons. The output neurons are evaluated to identify a location of the template in the test image.
