I have used inbuilt 'wdencmp' function for image denoising and my image got denoised, but I want to know how many coefficients were retained after reconstruction (IDWT)?
dwtmode('sym');
[thr,sorh,keepapp]=ddencmp('den','wv',input);
imgden=wdencmp('gbl',input,'db7',7,thr,sorh,keepapp);
and how does the quality of reconstruction vary with respect to number of DWT coefficients?
