python - Smoothing 2D contour with rough boundary in numpy array

Question

I have a contour that is represented in a numpy array in such a way that the boundary points have 1 and the rest are 0. An example image is shown below. How could I smooth this contour ?

I am trying the get a contour that is smoother than the one in the image right now

Answer 1

You can use active_contour to match a spline with a set number of points to your contour. If you lower the number of points you get a smoother contour.
