【今日翻译关键词】Channels、Candidate number、Target number、Window size

Channels: Specify which of the red, green and blue image channels will be used to match reference patterns. If one or more channels contains significant noise, or does not contain any useful pixel information, disabling these channels can often improve the accuracy of tracking.

通道:指定将用于匹配参考图案相的红色,绿色和蓝色图像通道。如果一个或多个通道包含明显的噪点,或不包含任何有用的像素信息,禁用这些通道往往能提高跟踪的精度。

Candidate number: Specify the number of candidate trackers to generate for each frame.

候选点跟踪数量:指定每一帧产生候选跟踪点的数量。

Target number: Specify the actual number of trackers to keep, after removing short-lived trackers from the set of candidates.

目标跟踪点数量:跟踪点数保持在从候选跟踪点集合中去除短命的跟踪点(很形象,就是错误的跟踪点)后指定的实际数量。

Window size: The size of tracker windows in pixels. Larger windows can often be tracked more easily, but take longer to process and can introduce drift if the contents of the window is changing significantly from frame to frame.

窗口大小:跟踪窗口的大小以像素为单位,较大的窗户往往可以更容易地跟踪,但需要较长时间处理,并且可以引入的漂移(个人理解是对搜索范围的补充),如果窗口的内容很明显的每一帧都变化。
