Make sure that floor(st2.EquivDiameter/2) is equal to 10.

@Image Analyst, thank you for your answer, but why floor(st2.EquivDiameter/2) should be equal to 10?

[Image Analyst]

I thought you said you wanted to grow the shape by 10 pixels. "I have managed to extend the size of original image, but it is not precise 10 pixels." - is that not what you want?

@Image Analyst, I would like to extend size of original shape, so I want to make white circle bigger.

imdilate() does that. I'm not sure why you then passed it through contour() instead of just calling imshow(mm_corn);
