Infrared target detection based on wavelet transform

Infrared target tracking is a new technology in controlling and guiding missile. It is based on artificial intelligence, image recognition, computer and high resolution sensor. The key of the image recognition, or target recognition is the edge detection, i.e. target detection. In this paper, the target detection method based on wavelet transform is introduced. Wavelet transform decompose a signal into basic block. It can present the signal in multiscale and have a good definition both in space domain and in frequency domain. So that, wavelet transform can present the singularity of the signal in local part.
