The active contour model is a method to fit open or closed splines to lines or edges in an image [ 1]. It works by minimising an energy that is in part defined by the image and part by the spline’s shape: length and smoothness. The minimization is done implicitly in the shape energy and explicitly in the image energy. aga fortnite editor
