梯度向量 meaning in English
gradient vector
Examples
- A knowledge - based arithmetic for automatic tongue segmentation
基于梯度向量流的医学图像自动分割 - Detection of motion - target based on improved gradient vector flow snake model
基于改进梯度向量流形变模型的动目标检测方法 - The gradient vector can be used to construct the initial errors
这时可以对梯度向量本身进行分析，或者用这个梯度向量构造初始误差场。 - Adjoint method provides an efficient tool to calculate the gradient vector of the cost function to the initial field
利用伴随方法，可以求出该度量函数关于初始场的梯度向量。 - Therefore the gvf ( gradient vector field ) is used to substitute the traditional potential field and it overcomes the defects of the traditional active contour
于是，我们采用一种梯度向量流场作为外力，从而有效地克服了传统势能场的弱点，给曲线的移动以很好的指向。
