I am attempting to use imfill to floodfill a donut shaped binary matrix. I am using version R2018b. I want to fill the donut (not the central hole) by sepecifying a pixel coordinate within the "dough". I am trying to run this command:
testFill = imfill(testShape, [3 3], 4)
As reccomended by the documentation:
BW2 = imfill(BW1,[3 3],8)
However, I get this error:
Error using imfill>parse_inputs (line 248)
Expected input number 3, OPTION, to match one of these values:
'holes'
The input did not match any of the valid values.
Error in imfill (line 124)
[I,locations,conn,do_fillholes] = parse_inputs(args{:});
Caused by:
Error using validatestring>checkString (line 89)
Expected input to be one of these types:
char, string
Instead its type was double.
