scale threshold meaning in English

比例界限

In object - oriented image analysis " scale " is not the pixel size , but the segmentation scale threshold . scale is different for each remote sensing im age analysis
面向对象影像分析中的尺度概念已不再是像元大小，而是指影像的分割尺度，是关于影像对象异质性最小的阈值。
Objects in different image levels are the aggregation of the initial pixels with the appointed scale threshold . this scaling method could avoid losing much meaningful information
不同尺度层上影像对象的属性信息是基于原始影像像元的整合，从而避免了重采样过程中损失大量的有用信息。
The algorithms employed in this paper are redesigned or improved for grid images . for example , an adaptable moving window gray scale threshold image segmentation method is proposed originally , a parallel template matching thinning algorithm is improved greatly , a sub - pixel image processing algorithm based on b - spline interpolation is present independently . 3
其中独立设计了自适应的移动窗口灰度阈值图象分割法，优化设计了并行模板匹配细化算法，独立提出了基于三次均匀b样条插值放大局部图象的亚象素图象处理算法，并都取得了较好的处理效果。
