MorphTool

An interactive environment for morphologically operating on images.

Description

MORPHTOOL is an interactive GUI, with which you can try different morphological operations and structuring elements on your image.

This GUI supports most morphological operations, including those (like BWHITMISS) that can take multiple STRELS. All STRELS, including arbitrary ones, are now supported. You can easily see the effects of changing the size or shape of your STREL, or of trying different morphological operations. You can also "activate" the modified image to string operations.

This has been in the works since mid 2007, but has been tested through R2011a.

CAVEAT: I'm still tweaking some aspects of this GUI, and know about a few issues and holes in functionality that I haven't had time to address yet. Nonetheless, I use it frequently, and everyone I've ever shown it to has asked me for it. Comments/suggestions/collaborations welcome.

• Required Products: Image Processing Toolbox
• MATLAB release: MATLAB 8.0 (R2012b)
• Other requirements: NOTE: I use tildes to ignore unneeded arguments; if you use a pre-R2009b version of MATLAB, you will need to replace those tildes with a variable name ('junk').

@Amarjot:
In R2009b, we allowed the use of a tilde to ignore unwanted function outputs:

[~,strelButtons,strelSliders] = StrelTool(strel1Parent);

If you're using an earlier version, you should 1) replace the tilde with a dummy variable (like "JUNK"); and 2) update your MATLAB!

Cheers,
Brett

Brett, on an unrelated note
I tried contacting you but didnt get a reply. where can I find the demo files for your webinar on medical image processing ?

[Amarjot]

Hi,
??? Error: File: MorphTool.m Line: 218 Column: 3
Expression or statement is incorrect--possibly unbalanced (, {, or [. can you please help me correct itt

[Brett Shoelson]

@Vinny:
narginck was added to MATLAB in R2011b. You can safely comment out that line, or replace it with:
nargchk(0,2,nargin)

(But you should upgrade! :) )
Cheers,
Brett

[Vinny]

im getting the following error (using matlab R2011a) :
"??? Undefined function or method 'narginchk' for input arguments of type 'double'.

Error in ==> MorphTool at 40
narginchk(0,2);"

@srinivasarao:
Sorry...not sure what paper you're talking about. This GUI agglomerates many of the morphological operations enabled through the Image Processing Toolbox, and allows interactive manipulation of all of their input parameters. There's no single paper to share.
Brett

[srinivasarao]

hi Brett,
can u send me the base paper

[Brett Shoelson]

I should clarify my previous comment. BWHITMISS does not _require_ two strels, but it does allow a 2-strel syntax.
Brett

[Brett Shoelson]

Hi Anoosha,
Thanks for the rating! Some morphological operations (notably here, BWHITMISS) require the specification of two structuring elements. For the purposes of MorphTool, SE1 is read from StrelTool1, and SE2 is read from StrelTool2.
Cheers,
Brett

[Anoosha Papireddy]

Hi Brett,
Could you please tell me what the difference between strelTool and strelTool2 is?

[Brett Shoelson]

Caleb: I believe that the zip file creates a subdirectory that contains the helper files (including tabPanel). Please either drag them out of that folder, or add the folder to your MATLAB path and try again!

[Caleb]

I'm using R2011b and I'm getting "Undefined function 'tabPanel' for input arguments of type 'cell'.

[Chien-Chun Yang]

 

[Brett Shoelson]

Hi Bella,
Can you tell me how to recreate the error you're seeing? I never assigned a callback to a uipanel, nor have I seen that particular error. Is it reproducible? How can I trigger it (so I can figure out what's going on)? And what does "I have put the files outside the folder" mean? (I wonder if this is a path issue.)
Cheers,
Brett

[Bella Sam]

Hello, I am using 2009a, and i have put the files outside the folder..i have some problem and didn't know what these means::

??? Error using ==> get
There is no 'Callback' property in the 'uipanel' class.

Error in ==> iptaddcallback at 71
current_callback = get(h, callback);

Error in ==> MorphTool at 648
iptaddcallback(strelButtons(ii),'Callback',@morphOp);

[Brett Shoelson]

Parth,
Can you give me some details about your MATLAB? Do you have the Image Processing Toolbox? What version of MATLAB are you using?
Thanks...Brett

[Parth]

hey there m gettin an error as this one:

??? Undefined command/function 'iptchecknargin'.

Error in ==> MorphTool at 24
iptchecknargin(0,2,nargin,mfilename);

[recep]

thanks alot it's work

[Brett Shoelson]

recep, Kelly, et al: I see what's happening now. I provided auxiliary files in a folder, assuming that they would be put on your MATLAB path. You can either add those folders manually to the path, or drag the files out of the folders, or issue this (or equivalent) command:

addpath(genpath(fileparts(which('MorphTool.m'))))

Let me know if that addresses the issue, please.

[Brett Shoelson]

@recep and Kelly: Would you please verify that you have the latest version, and that it came with the TabPanel function? If not, please grab the new version. If so, it would help if you could tell me reproduction steps that trigger the problem.
Thanks, Brett

[recep]

I use 2009a but I give problem like it:
??? Undefined function or method 'tabPanel' for input arguments of
type 'cell'.

Error in ==> MorphTool at 177
[mainTabHandle,tabCardHandles,tabHandles] = ...

[Brett Shoelson]

Please try again; I believe that the current version includes all the files you need to run this. (Please let me know if there are any additional issues with MorphTool...).
Thanks, Bret

[Kelly]

Thanks Brett you are right I am using 2009a and the 'junk' insert fixed that error... however now I am getting a different error.

??? Undefined function or method 'tabPanel' for input arguments of type 'cell'.

Error in ==> MorphTool at 177
[mainTabHandle,tabCardHandles,tabHandles] = ...

[Brett Shoelson]

@Kelly and YAZ (and others):

Thanks to you both. I just figured out that you are using a version of MATLAB that predates R2009b. (Correct?) I use tildes to ignore unwanted arguments; that capability was introduced in '9b.) TO FIX THIS: Either upgrade to a newer MATLAB ;), or replace the tildes in my code with some word like "junk." That should do it!

[Kelly]

I have the same error as YAZ
??? Error: File: MorphTool.m Line: 185 Column: 3
Expression or statement is incorrect--possibly unbalanced (, {, or [.

I did not backspace or delete anything and tried re-downloading it with the same error.

[Brett Shoelson]

@YAZ
Is it possible that you accidentally backspaced and deleted something? I don't see any indication of an unbalanced parenthesis in that file. Would you re-download and verify the error, and let me know if you still see it, please?
Thanks,
Brett

[YAZ]

hi, i have this message :
"??? Error: File: MorphTool.m Line: 185 Column: 3
Expression or statement is incorrect--possibly unbalanced (, {, or [."

[Brett Shoelson]

Bojan, Jonas: Should be good to go now...please re-try! Thanks for the heads up.

[Brett Shoelson]

Give me a few minutes, Bojan and Jonas. I accidentally omitted that file when I updated. Working on it.

[Jonas]

Same error here as Bojan - StrelTool seems to be missing from the package, which makes the potentially awesome submission unusable.

[Bojan]

I'm having a problem running this as it requires StrelTool. Is StrelTool available on file exchange or part of another toolbox?

[W]

Great!Thanks!

[Brett Shoelson]

@Nayanjyoti: You are correct: the file is 'cameraman.tif'; my code should reflect that. My windows machine has case-insensitive filename matching, which allowed me to be sloppy. Your Unix environment (correct?) is not. I'll modify the file.

[Nayanjyoti]

Hi Brett, I tried using a maci64 and glnxa64 and my experience was that when you do
>> I = imread('Cameraman.tif');

you get the following error
??? Error using ==> imread at 372
File "Cameraman.tif" does not exist.

whereas,
>> I = imread('cameraman.tif');
works fine.

[Brett Shoelson]

@Nayanjyoti: Thanks for the feedback; I plan to continue ot expand MORPHTOOL. Actually, though (on a PC at least), imread is insensitive to the case of an input image name. So both "imread('Cameralman.tif')" and "imread('cameraman.tif')" work. (IMREAD calls FOPEN under the hood.) Do you see different behavior?

[Nayanjyoti]

In line 11
"imgName = 'Cameraman.tif';" needs to be replaced with
"imgName = 'cameraman.tif';"

[Nayanjyoti]

Simply mind-blowing. Would like to see it include more functionality.

[Brett Shoelson]

Sami,
Thanks for the rating. I programmed the GUI manually, without the use of GUIDE. You don't need a .fig file to run it. Just issue the command 'morphtool' (or 'morphtool(myimage)') to run it.
Cheers,
Brett

[Samiov]

it looks great...but how make it works??? the .fig file isn't in the zipfile!! or I just must be inspired from the .m file???
