Abstract
An electronic image classification and search system and method are provided. Images are processed to determine a plurality of simple feature descriptors based upon characteristics of the image itself. The simple feature descriptors are grouped into complex features based upon the orientation of the simple feature descriptors. End-stopped complex feature descriptors and complex feature descriptors at multiple orientations are grouped into hypercomplex feature descriptors. Hypercomplex resonant feature descriptor clusters are generated by linking pairs of hypercomplex feature descriptors. Feature hierarchy classification can then be performed by adaptive resonance on feature descriptors and classifier metadata associated with the image can then be generated to facilitate indexing and searching of the image within a hierarchical image database.
