Infrared Image Sequence Small Target Recognition Method Based on Wavelet Transform Domain

In order to reduce the recognition time of small target in infrared image sequence, a small target recognition method based on wavelet transform domain is designed. Firstly, the noise of infrared image is analyzed, and the image is denoised. Then the infrared image is decomposed by wavelet transform domain. Finally, the small target recognition of infrared image sequence is completed based on wavelet transform domain. Experimental results show that the proposed method not only shortens the recognition time, but also improves the accuracy of small target recognition.
