| Abstract: | Based on the fixed IR system detecting the point target in the offing,this paper presents four kinds of optimizing algorithm to resolve the real-time problem.They are the algorithm of compressing the inspect area,the multistep algorithm based on risk factor,the algorithm of abandoning the low frequency section after wavelet transform,and the algorithm of inspecting the signal whose amplitude is zero in the infrared imagery.These kinds of algorithm not only reduce the operation steps,enhance the speed of the system,satisfy need of the system in real-time requirement,but also reduce the false warning frequency of the system,ensure the effect that IR system restrains strong fluctuation circumstance. |
