A colour active contour model for contour extraction in natural scenes
The performance of active contours, originally introduced as snakes, depends on the proper selection of model parameters and initial contours. In natural scenes, active contours often fail to converge to the desired solution because of unconstrained environmental conditions and complex object shapes...
