MATHEMATICAL MORPHOLOGY SIGNAL PROCESSING METHOD BASED ON SPARSE STRUCTURAL ELEMENTS

摘要

Disclosed in the present invention is a mathematical morphology signal processing method based on sparse structural elements, comprising the steps of: 1) building sparse structural elements; 2) performing morphology filtering on a signal by using the sparse structural elements; 3) improving the filtering effect for the filtering result by using a multi-stage sparse algorithm or a two-stage sparse algorithm; 4) building free structural elements and a bipolar morphology gradient; and 5) performing bipolar morphology gradient extraction on the signal by using the free structural elements. The present invention can effectively reduce the calculation amount and calculation time of mathematical morphology signal processing, and enhance the amplitude of the morphology gradient.
