Abstract:Based on mathematic morphology filtering, a real-time detection algorithm for infrared small target and its realizing technology on DSP hardware are proposed. Firstly, the small target detecting process is analysized and the improved morphology filtering algorithm for target detection is introduced. Secondly, based on the algorithm’s charac teristic, its implementingmethod and procedure on DSP64X are p resented. Finally, the running result of algorithm on infrared detecting system is given and analysized. The experiments show that the method can fleetly and reliably detect the small targetwith low SNR, which has achieved the demand of high performance.
