Several frequently used filter algorithms for point target detection in the image tracking system are introduced and compared in detail. To meet the requirement of real-time image processing. A set of hardware structure in FPGA is designed for implementing image filtering algorithms. The structure takes full advantage of high speed and parallel processing ability of FPGA . Multiple filtering processing are simultaneously implemented in real time just when image signal is read out. Experiments prove that the design of the structure is successful which gives a perfect real-time filtering result.
