Based on the theory of discrete wavelet transform,a scene-based nonuniformity-correction algorithm for infrared focal plane arrays(IRFPA) is presented.In this scheme,the infrared image sequence is decomposed to the discrete sequence wavelet transform with an appropriate wavelet function,and an operation flow based on Mallat algorithm is given,and an infrared imaging system is designed to carry out real-time nonuniformity-correction.The system uses high-performance DSP(TMS320C6713) as the core processor,and ...
