Wavelet Toolbox

Importing and Exporting Information from the Graphical Interface

The tool lets you save the de-noised image to disk. The toolbox creates a MAT-file in the current directory with a name you choose.

To save the de-noised image from the present de-noising process, use the menu option FileSave De-noised Image. A dialog box appears that lets you specify a directory and filename for storing the image. Type the name dnoiswom. After saving the image data to the file dnoiswom.mat, load the variables into your workspace:

• load dnoiswom
  whos
  

Name	Size	Bytes	Class
X	96x96	73728	double array
map	255x3	6120	double array
valTHR	3x4	96	double array
wname	1x4	8	char array

The de-noised image is X and map is the colormap. In addition, the parameters of the de-noising process are available. The wavelet name is contained in wname, and the level dependent thresholds are encoded in valTHR. The variable valTHR has four columns (the level of the decomposition) and three rows (one for each detail orientation).
