I tried erode followed by a dilate.
The effect is not good as I want it to be.
I want the edge without any curve. It better can remove the curve and use straight line to represent those curve
I remember that there are some filter for smoothing the edge,right?

You can try activecontour(). You can set parameters to control how smooth the boundary is. See attached demo.

It's the same function. You forgot to give the error message. Please copy and paste ALL THE RED TEXT. Don't snip or paraphrase like you did. Did my demo run? That should run with no errors whatsoever.
