Abstract

In this paper, a contour-fitness improved adaptive snake, namely, edge-conducted rectification-adapted snake (ECRA-snake) is proposed for segmenting complex-boundary objects in the noisy image. The ECRA-snake includes a main ingredient called edge-conducted evolution (ECE), where the adaptations of model coefficients can accommodate ECE itself to the characteristics of salient edges for better curve fitting in tracking. Following ECE, a direction-induced rectification evolution (DIRE) will correct boundary-unmatched snake fragments by handling the initial direction and the tensile-force weighting of unqualified snaxels in this snake re-evolution. Simulation results demonstrate that the proposed ECRA-snake can obtain better object-boundary coincidence than the Gradient Vector Flow (GVF) model in segmenting the complex-boundary object from noisy images.
