Mammogram microcalcification Enhancement using NSCT

algorithm to enhance the using nonsubsampled contourlet transform

Description

files: procesaM.m, procesaM.fig and 3 images with microcalcifications.
To work Must be installed the NSCT toolbox first, available in matlab central.
The main function is located on procesaM.m and could be pasted in other code.

• MATLAB release: MATLAB 7 (R14)

The algorithm appears on the article "The Nonsubsampled Contourlet Transform for Enhancement of Microcalcifications in Digital Mammograms" by
 Jose M. Mejía; Humberto de J. Ochoa Domínguez; Osslan Osiris Villegas Vergara ; Vianey Guadalupe Sánchez Cruz and Leticia Ortega Maynez.

there is a error when i press start button...its shows Error in ==> ProcesaM at 42
    gui_mainfcn(gui_State, varargin{:});
what to do

[Jose]

you must have installed the NSCT toolbox first ( available in matlab central), and have it in the search path.
When you run the application first do a click on the "open image" button, to select a mammogram image to process, and then push the "start" button. The algorithm takes a lot of time to process.. like a couple of minutes.. sorry

I added the NSCT toolbox in the search path by "path('U:\Image_Processing_program\nsct_toolbox',path)", then run the program by clicking "ProcesaM.fig" and the "ProcesaM" popup comes up. I clicked the "Open Image" an "UIGETFILE TITLE" window pops up. Then I chose an image, say, mdb252_256.bmp, by clicking "Open", an error message shows up as follows:
??? Reference to non-existent field 'Original'.

Error in ==> ProcesaM>BotonCargar_Callback at 92
axes(handles.Original);

Error in ==> gui_mainfcn at 96
        feval(varargin{:});

Error in ==> ProcesaM at 42
    gui_mainfcn(gui_State, varargin{:});

??? Error while evaluating uicontrol Callback

I'm using R2008a. What to do to solve the problem? Thanks!

[Jose]

Hi George,
 I can't reproduce the problem here. I will try run the program with someone who uses the R2008 version and see whats going on.

In any case this is what the program is trying to do at the error line:

On line 92, I just select the axis where the opened image is displayed:

Error in ==> ProcesaM>BotonCargar_Callback at 92
axes(handles.Original);

handles.Original is the axis name.

Sorry (for the moment I hope)

Jose

Dear Jose,
  I tried to downland this article "The Nonsubsampled Contourlet Transform for Enhancement of Microcalcifications in Digital Mammograms on network.But I cann't find the article as you give.would you send me the article? My E-mail is [e-mail].
Thanks! I am look forward to hear from you.
