Active contour

Method in computer vision for delineating an object outline from a 2D image.

Also called a snake is technique for detecting and segmenting objects using deformable curves which will match the objects. It relies on a deformable model controlled by an energy minimization function. This energy depends on the image and also on the parameter we want to give to our deformable contour.

Code inputs:

• Insert an input image name example: square.jpg
• Get input from user if 1 let user determine initial contour points else initialize it as a circle
• If the initial contour is a circle, it would be placed at the center of the image with a radius equal to 45% of the minimum image dimension
• Get input from user if 1 do beta relaxation
