T-snakes: Topology adaptive snakes
Medical Image Analysis, 2000We present a new class of deformable contours (snakes) and apply them to the segmentation of medical images. Our snakes are defined in terms of an affine cell image decomposition (ACID). The 'snakes in ACID' framework significantly extends conventional snakes, enabling topological flexibility among other features. The resulting topology adaptive snakes,

Snakes in Suits: When Psychopaths Go to Work
, 2015"Snakes in Suits" is a compelling, frightening, and scientifically sound look at exactly how psychopaths work in the corporate environment: what kind of companies attract them, how they negotiate the hiring process, and how they function day by day.

BMC Evolutionary Biology, 2015 The highly derived morphology and astounding diversity of snakes has long inspired debate regarding the ecological and evolutionary origin of both the snake total-group (Pan-Serpentes) and crown snakes (Serpentes).

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.

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.

Humans quickly detect the presence of evolutionary threats through visual perception. Many theorists have considered humans to be predisposed to respond to both snakes and spiders as evolutionarily fear-relevant stimuli.

Pulmonoscopy is a practical diagnostic tool for investigating respiratory diseases in snakes. Two different approaches exist for pulmonoscopy, tracheal and transcutaneous. The access to the proximal or distal lung is limited by the length and diameter of the endoscope when using the tracheal approach.

SIAM Journal on Numerical Analysis, 1996
Summary: We propose a geometric partial differential equation (PDE) for tracking one or several moving objects from a sequence of images, which is based on a geometric model for active contours. The active contour approach permits us to simultaneously handle both aspects: finding the boundaries and tracking them.
