Other AbstractThe invention discloses a rapid computation structure for image geometric moments and central moments, which comprises grids of a digital filter, a geometric moment computation unit, a centroid computation center and a central moment computation unit, wherein image data is embedded in the grids of the digital filter, and the grids of the digital filter perform regular iterative computations under a pixel clock and a frequency-doubling clock the geometric moment computation unit couples outputs of different nodes of the grids of the digital filter from the grids of the digital filter, and the geometric moments of images are obtained the centroid computation unit uses computation results of the geometric moments as input data and performs centroid computation under the pixel clock, and the outputs of the geometric moments are coupled to obtain the geometric moments the input data of the central moment computation unit come from the geometric moment computation unit and the centroid computation unit, the outputs of the geometric moments and the centroid moments are coupled, and the central moments of the images can be obtained. The rapid computation structure has the advantages of little occupation of logic resources and rapid computation speed, and has good usage value in the fields of target identification and detection.
