  • Basic principles of dim target detection based on the wavelet transform is analyzed. According to the multi-scale and multi-direction in the wavelet coefficients and combining with the selectable diffusion direction characters, a new method is designed to denoise and detect small targets by the diffusion filter in different directions and different scales of wavelet coefficients, respectively. Combined a anisotropic filter, the algorithm is used to a diffusion filtering experiment for wavelet coefficients. Results show that the algorithm can detect the dim target with a contrast of 2%, and has better performance in the detection of dim target, robustness to Gaussian noise and uneven backgrounds.
