Application of wavelet transform in image denoisin
no vote
The basic idea of threshold denoising: contains a certain noise by Wavelet transform of the image, the
image of the main message will be focused on low-frequency Sub-bands in Wavelet domain, (White)
noise is evenly distributed over all of wavelet coefficients. When the high frequency subbands of wavelet
domain coefficients when a choice is made, should be the main removal Noise factor. High frequency
subband, because noise is evenly distri
