运动目标的检测与跟踪是紧密关联的两个过程，跟踪始于检测，而目标在后续图象序列中的重复检测也有助于目标的跟踪。

These two processes are closely related because tracking usually starts with detecting objects, while detecting an object repeatedly in subsequent image sequence is often necessary to verify tracking.

这里是一个方法你可以优化图象：重复看上去很平的层，设置为覆盖模式。

Here is a trick you can use when refining an image: duplicate flattened layer and set to Overlay Mode.

且具有自动化程度高、操作简单、使用方便、准确度高、图象数据可存储、打印输出与重复使用等明显优点。

This system has many remarkable advantages, such as high automation, simple operation, easy usage, high precision, and the image obtained can be saved, printed, or reused.
