Image hybrid denoise algorithm based on wavelet transform
Wenlong Jiang · Journal of Changchun University of Technology · 2008
An efficient algorithm based on wavelet transform to remove the noise in the image is proposed,in which,the wavelet coefficients of the image edge features are determined before denoising.The coefficients are kept while the other are denoised with adaptive threshold to remove the Gaussian noise.Then the image is dealt with median filter to remove the noises.The experiment results show that the algorithm not only can efficiently remove the mixed and Gaussian noises but can keep image edge details as well.The filtering performance is better than that of traditional methods.
