Research on Infrared Image Guidance Tracking Algorithms Under Low SNR
低信噪比红外成像制导跟踪算法研究

The infrared images of low signal-to-noise ratio(SNR)are analyzed according to the char- acteristics of infrared images.A preprocessing method based on background suppression is proposed. The contrast tracking algorithm and the correlative tracking algorithm usually used for infrared image guidance under different combat environment and requests are summarized.Finally,the applications and tracking effectiveness of these two algorithms are compared.
