Hi, You have a couple of options.
1.) use wavemenu. Enter wavemenu at the command line and then choose, Wavelet 2-D, or SWT Denoising 2-D. Starting in R2011b, you can generate MATLAB code for your denoising directly from the wavemenu GUI.
From the command line, you can use wavedec2 and wdencmp, for decimated 2-D Wavelet denoising, and swt2 and wthresh or stationary wavelet 2-D denoising.
There are some good User's Guide examples of using the GUI and generating MATLAB code for 2-D denoising here:
Note that the generated code in these examples also shows you how to implement 2-D wavelet denoising from the command line.

for image de-noising using stationary wavelet transform and threshold techiques I have used
THR = wthrmngr('sw1ddenoLVL',METHOD,SWTDEC,SCAL)
command swtdec =db1,scal= 2 ,method ='rigsure'.
couldn't decompose the original image and hard and soft threshold used . plz replay me sir id:firstname.lastname@example.org
