We propose a novel external force for active contours by normalizing normal and tangent components of the gradient vector flow…
3D梯度向量流场（3D GVF field）广泛应用于多种3D图像分析算法中,其计算需要多次迭代,计算量大,如何提高其计算速度具有重要的研究意义.面向Intel Xeon Phi众核集成架构,首次进行了3D GVF场计算的加速优化.首先,挖掘3D…
In this paper an object tracking system with utilizing optical flow technique, and Gradient Vector Flow (GVF) active contours is…
Poor convergence to concave boundaries is a limitation in the use of snakes as a contour approximation technique. The external…
GVF 스네이크 알고리즘은 에지 에너지에 상당히 민감하여 주변 에지와 객체의 윤곽선이 포함하고 있는 에지를 구분하지 못하여 정확한 객체의 형태를 추출하기가 어렵다. 본 논문은 배경으로부터 객체의 윤곽선을 추출하기 위해 GVF…
Gradient vector flow (GVF), an elegant external force for parametric deformable models, can capture object boundaries from both…
