ZHOU Xin, LIN Yu-chi, SONG Le, et al. Infrared image denoising based on Contourlet transform[J]. 2008, (3): 37-38+42. DOI: 10.13873/j.1000-97872008.03.016.
A denoising method of infrared image based on Contourlet transform is presented.In selecting the hard threshold function to process the coefficients in the Contourlet domain
the denoised image of superior quality via inverse transforming can be thereby obtained.The result of the experiment indicates that compared with the traditional algorithms of the wavelet
this method can preserve the detail and the texture more effectively
