Other AbstractThe invention relates to an image Gaussian filtering method with a dynamically configured mode and a realization device thereof. A field programmable gate array dynamically configures filtering modes according to different requirements; under the corresponding filtering mode, a two-dimensional image Gaussian filtering process is decomposed into two one-dimensional image Gaussian filtering processes by use of the separability of a Gaussian convolution kernel; the Gaussian filtering in one-dimensional direction is firstly carried out; the Gaussian filtering data is cached in a memory in FPGA (Field Programmable Gate Array); the Gaussian filtering in the other dimensional direction is carried out; and the Gaussian filtering in the dimensional direction is subjected to shift processing to obtain a final Gaussian filtering image in the filtering mode. The image Gaussian filtering method disclosed by the invention has a flexible use mode, the development difficulty is reduced, the developing period is shortened, the Gaussian filtering with large size can be effectively realized in a project, and the practicality of the Gaussian filtering in the project is enhanced.
