Abstract

We demonstrate the use of informational redundancy of signals for reducing the computational costs of signal processing. An accelerated algorithm for computing local, or short time, histograms of signals is proposed to support the idea of purposive use of signal redundancy for saving computational costs. Different rank-order filters using a large moving window can be designed on the base of the proposed algorithm. Computer tests and application of the algorithm to rank-order processing of real-life images are provided and discussed.
