To Do: image denoising in wavelet domain

Section: Wavelets

Data

Images you want (you can use Barbara provided in the Fourier section)

To do

  • Simulate a noisy version of the image using the noises at various SNR Level (0 db, 10 dB and 20 dB)
  • Denoise the image by performing hard thresholding and soft thresholding in the wavelet domain
  • Discuss the parameters (wavelet type, number of level, type of thresholding)
  • Denoise the image by implementing translation invariant wavelet transform (see the numerical tour on image wavelet denoising )
