- W2376909743 abstract "The images in the practical application affected by a lot of noises interferences,in order to make better use of noising images,in the paper,according to the characteristic of energy distribution of wavelet packet and noises,a method of image noise reduction is proposed.Firstly,noised image is decomposed by wavelet packet with more scale.Secondly,the square margin of noise and threshold in high frequency coefficients of wavelet packet with different scale are figured out.And the coefficients are processed with different thresholds.Finally,reconstructed image can be obtained by using inverse wavelet packet for all coefficients and compared with the method of the all threshold denosing.The experimental results prove that by using this method,noising images can be reduced effectively and image details can be better preserved." @default.
