Abstract :
By exploring parallelism, novel three-dimensional (3-D) recursive ladder filter structures for implementing a class of 3-D frequency-planar and 3-D frequency-beam filters are developed. These structures use discrete differentiators and are suitable for high-speed real-time processing of video image sequences
