Matlab中未定义的函数错误

Question

function im = Thresholding(I)
[r,c] = size(I);
im = zeros(r, c);
for i = 1:r
for j = 1:c
    if I(i,j)> 105
        im(i,j) = 1;
    end
end
end
im = bwareopen(im, 5);
im = imfill(im, 'holes');
end 

I'm trying to use this code and I got this error " Undefined function or method 'bwareopen' for input arguments of type 'double'"please help me

Answer 1

You're calling bwareopen but you should be calling bwareaopen . The latter has an extra a.
