Snake Active Contour Javascript Implementation v1.1 (by Jae Shin)

Uses 100% Javascript and KineticJS for image processing.
// Good parameters - zen_circle.png: gamma=13, alpha -1.5, beta 5, wl=-1.1 (negative value means expanding snake) // brain.png: closed snake, alpha=3,beta=5,kappa=4,gamma=40
// gradient-diag-300.jpg: open snake, alpha=1,beta=1,wl=1

Image Gauss Blur # points/segment

Click Mode Snake Mode alpha beta
gamma (faster) (slower iteration)

animate | Iteration Internal (second)

wl we wt Ext Energy kappa Lower kappa = less snake energy influence, higher kappa = more image forces

(use lower gamma for volcano)
