Error when using createMask
12 views (last 30 days)
I am trying to develop a code in which I want to modify a figure. However, when I call createMask, I get an error saying "Undifined function or variable 'createMask'.
This is the code:
% read the original image
I = imread('TEST.PNG');
% call createMask function to get the mask and the filtered image
[BW,maskedRGBImage] = createMask(I);
% plot the original image, mask and filtered image all in one figure

A mask is created from an ROI (region of interest), not an image. First you need to create an ROI with drawellipse, drawfreehand, etc. Then you can create a binary mask.
See the documentation for createMask for a good example.
