中文拼音 [gǔchènshǐliáng]
滑稱矢量
英文
glide vector-
The proposed algorithms have good performances. some improvement on the gvf snake algorithm is presented to solve the problem of gvf snake ' s inability to converge to the rough contour of the brain. a variable vector field is designed and the constraint parameters of the gvf field is made adaptable to the target object features
本文的研究工作主要包括以下幾個方面:針對gvfsnake演算法提取腦輪廓時不能很好的收斂于光滑性差的腦輪廓的問題,對gvfsnake演算法進行了改進,構建了一動態變化矢量場,把gvf場的約束權值設為隨目標特徵自適應變化,從而提出了一種新的演算法,稱之為agvf ( adaptablegradientvectorflow ) snake 。
