@Davide

Dear Davide,

I am sorry I did not see your comment on time. DWT2 comes with Wavelet Toolbox and UPSAMPLE comes with Signal Processing Toolbox, respectively.

I hope this helps.

Sir, Thankyou for yr submsn, very helpful to all.
Pls kindly answer:
How the threshold value in your file cvt_th_4_3445_mean_lasl_zero.mat are decided? Means how you decide the threshold value for this process?

Pls kindly consider my question and yr answer will very useful to me and all.

very good thank you

10 Apr 2014 PURE-LET for Poisson image denoising This is an implementation of the PURE-LET, recently proposed for Poisson image denoising. Author: SANDEEP PALAKKAL Nia

Thank you for this submission. While it is working very well for 8-bits image, it does not work for 16 bits. How can I change it top work for that class of image ?
