??? Attempted to access im3(217,0); index must be a positive integer or logical.
Can anyone teach me how to change my im3 to logical?

You do not have to change the picture, but the index - as the error message explains. Indicies start at 1 in MATLAB, such that "im3(217, 0)" is not valid. I guess that "im3(218, 1)" solves your problem.
