Medical Image Analysis, 2006
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 framework called "United Snakes", which has two key features. First, it unifies the most popular snake variants, including finite difference, B-spline, and Hermite polynomial snakes in a ...

IEEE Transactions on Image Processing, 2007
Active contours, or so-called snakes, require some parameters to determine the form of the external force or to adjust the tradeoff between the internal forces and the external forces acting on the active contour. However, the optimal values of these parameters cannot be easily identified in a general sense.

Clinical Techniques in Small Animal Practice, 2006
North American coral snakes are distinctively colored beginning with a black snout and an alternating pattern of black, yellow, and red. They have fixed front fangs and a poorly developed system for venom delivery, requiring a chewing action to inject the venom.

Image and Vision Computing, 2007
Energy minimizing contours or snakes are tools for delineating objects of interest in an image. Snakes are defined discretely or in continuous form with continuous snakes having advantages over discrete snakes. A continuous snake called B-snake has been previously defined using B-spline curves.

Biological Reviews, 1951
Summary1. Current theories of ophidian evolution suggest that the snakes have been derived either from aquatic, above‐ground terrestrial, or burrowing ancestors. It is generally supposed that the ancestors of snakes, irrespective of their habits, were closely related to the platynotid lizards.

From splines and snakes to snake splines
1993Segmenting 3-D complex medical objects from sets of parallel slices may be a difficult task. We propose a new method of active contours (or snakes) that simplifies the classical approach of snakes by embedding the intrinsic energy in the spline nature of the surface to deform.

Effects of Snake Venoms on Snakes
Copeia, 1946IN 1931 I started a series of experiments on snake venoms in order to procure comparative data on the effects of venoms on various species of snakes. The war brought the work to a standstill in 1941, after I had concluded 58 experiments. Although the small number of experiments does not permit definite conclusions to be drawn, the work is now ...
