Abstract
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.关键词
