A Hierarchical Image Analysis System Based Upon Oriented Zero Crossings of Bandpassed Images

摘要: In this paper the use of oriented zero crossings bandpassed images as representational primitives for hierarchical operations is discussed. Some theoretical properties are presented and a hardware system production zero-crossing “pyramid” proposed. The processor utilizes set “systolic” array processors which implement two-dimensional digital lowpass bandpass filters well detectors orientation measurements. A multilevel interleaved described allows concurrent processing two sets image descriptions ensures that component elements utilized to fullest. Results provided by simulations applied real imagery described.
