Since their debut in 1987, snakes (active contour models) have become a standard image analysis technique with several variants now in common use. We present a portable, reusable, software package called `United Snakes'. The package unites the most popular snake variants, including finite difference, B-spline, and Hermite polynomial snakes within the mathematical framework of a general finite element formulation with a choice of shape functions. The package furthermore incorporates a recently proposed snake-like technique known as `livewire'. We integrate snakes and livewire by introducing an effective method for imposing hard constraints on snakes. Our experiments demonstrate that snakes and livewire have complementary strengths and that their union offers a more powerful tool for interactive image analysis, especially for medical imaging applications. United Snakes is implemented in Java as a JavaBean so that it can easily be integrated in end-user application systems.
