取阈值 meaning in Chinese

thresholding

With the exemption of simple techniques like thresholding, segmentation algorithms require the examination of each point in comparison to its neighbours .
与取阈值的简单方法不同，分割算法需要把每点与其近邻作一一比较。
Our experiments show that the new method overcomes the disadvantage of image segmentation with one - dimension maximum entropy and keeps the original edge features well . this method is simple
实验表明，本方法可以克服目前已有的一维最大熵取阈值方法进行图像分割时，由于阈值取的太低而丢失细节信息的缺点，有效地保留了边界的细节特征。
A probability model of distribution for perspective image ' s background and objects was put forward , and a formula was deduced to compute the optimized segmentation threshold based on the probability model
并基于此模型推导出根据概率模型计算最佳分割阈值的公式，不同于传统方法反复计算和比较准则函数求取阈值的方式，只需要将图像数据代入文中所建立的模型，求解一元二次方程即可快速求得最佳阈值。
