i'm using matlab coder to convert my code to C. i'm facing problem in converting some built in function of matlab as imfill, regioprops etc. following is the line of code:
outer_blob = imfill(bin,'holes');
and error is:
Expected input number 2, CONN, to be one of these types: double, logical
as, i see in imfill my syntex is correct for code genration. please help me out.

What is class(bin) ? Telling me that it is a binary image does not tell me whether bin is logical, or is double that uses values 0.0 and 1.0, or is uint8 that uses values uint8(0) and uint8(1), or is uint8 that uses values uint8(0) and uint8(255)

Have you tried
outer_blob = imfill(bin, 4, 'holes');
in case this is a bug in matlab? (I don't have coder so can't test)

Which MATLAB release are you using?
Note that according to the documentation, when you compile,
  • Input argument 'holes' is not supported, if the input is a binary image.
