STATCHANGE is the percentage change threshold value for all tables in your system.
STATCHANGE是指系统中所有表的修改阈值,采用百分比形式。
The table property is used to set the change threshold for that specific table and its indexes.
该表属性用于针对特定表及其索引设置修改阈值。
You can use the table property STATCHANGE if you wish to control the change threshold at the table level instead of system level.
如果希望在表级别而不是在系统级别控制修改阈值,可以使用表属性STATCHANGE。
In this mode, the server allows you to define a data change threshold and refresh statistics only if the data has changed beyond the threshold since they were last built.
在这种模式下,服务器允许您定义一个数据改变阈值,并且只有在数据自最近一次建立后的变化超过了阈值才会刷新统计数据。
This paper describes how to detect change of land with multi-temporal remotely sensed image. The key is how to match images, detect change and confirm the change threshold.
该文在多时相遥感图像中采用主成份差异法提取耕地变化信息,研究的关键在于差值前如何进行图像匹配、如何自动提取变化信息以及差值后如何确定变化阈值。
