In practice of image processing using scikit-image, I didn't understand the role of constructing init numpy array in Active Contour Model example. Is it the red section drawn in the example astronaut image?

Active contour is just refining your initial contour.

You could play yourself with the model :)

  • $\begingroup$ Yes, you may have other contour detection, and you use active_contour, for instance, to smooth the contour. $\endgroup$

  • $\begingroup$ You can how the red dashed lines are plotted. ax.plot(init[:, 1], init[:, 0], '--r', lw=3) Yes, simply the init path. $\endgroup$
