See the imfill documentation for more syntaxes that don't require interactive input,

    BW2 = imfill(BW)
    [BW2,locations] = imfill(BW)
    BW2 = imfill(BW,locations)
    BW2 = imfill(BW,'holes')
    I2 = imfill(I)
    BW2 = imfill(BW,locations,conn)

hi thanks Matt

I use BW2 = imfill(BW,'holes');

It gives me what I want but it gives me this error:

Error using handle.handle/get Invalid or deleted object.

Error in getcurpt (line 14) pt = get(axHandle, 'CurrentPoint');

Error in getpts>FirstButtonDown (line 220) [x,y] = getcurpt(GETPTS_AX);

Error in getpts (line 37) feval(varargin{:});

Error while evaluating figure WindowButtonDownFcn

The error messages don't mention imfill anywhere. Wherever the error is coming from, it's in a different part of your code.

Did you change the "current folder" in MATLAB after you launched your GUIDE app?

yes Image Analyst

when I put my image in the folder that my code saved I did not any error after run my code. thanks Matt

thanks Image Analyst

That doesn't make sense. There is an image on disk, and then a bunch of images in memory. For you to have even gotten to a point in your code where you've created a BW variable, you must have already successfully read in your image from the file in your folder into a variable in your program. Then you thresholded it to get BW - BW is in your program memory, not in the folder. So that could not have been the problem.
