A Comparative Study of Wavelet Thresholding for Image Denoising

  title={A Comparative Study of Wavelet Thresholding for Image Denoising},
  author={Arun K Dixit and Poonam Sharma},
Image denoising using wavelet transform has been successful as wavelet transform generates a large number of small coefficients and a small number of large coefficients. Basic denoising algorithm that using the wavelet transform consists of three steps – first computing the wavelet transform of the noisy image, thresholding is performed on the detail coefficients in order to remove noise and finally inverse wavelet transform of the modified coefficients is taken. This paper reviews the state of… CONTINUE READING
