| Abstract: | In order to improve joint transform correlator(JTC) for recognition ability of low-contrast target in cluttered background,a new object plane filtering method is proposed based on the combination of wavelet transform,gray stretching and Canny operator.Finally,a new object plane processing filter is designed.The computer simulation and optical experiments show that this method can extract the target feature accurately,reduce the noise effectively and obtain bright correlation peaks.The recognition problem of... |
