Search range: The width and height of the search range in pixels to use for the initial pattern search. This option is only available when the search mode is set to either better speed or better accuracy. Note that the search area defines the possible locations of the centre-point of the tracker, rather than the entire tracking window itself.

搜索范围:用于初始模式搜索的搜索范围的宽度和高度以像素为单位。此选项仅当搜索模式将被设置为了更快的速度或更好的精度。请注意,搜索区域定义了跟踪中心点的可能位置,而不是整个跟踪窗口本身。

Pick threshold: The threshold used to identify new tracker positions in the range zero to one. New trackers are positioned at corners and significant image gradients. The higher the threshold, the stronger the corner or image gradients need to be before a tracker is created. Setting this to a very small value will position trackers on weak corners where they may not track well.

挑选的阈值:阈值用来确定新的跟踪点位置(介于0到1之间),新跟踪点会产生在边角和图像梯度明显的位置(就是像素值对比明显的边界处)。阈值越高,越强的角落或图像梯度越明显处将会优先产生跟踪点。将其设置为一个很小的值,将会在薄弱的角落里产生跟踪点,这样可能导致跟踪结果不好。

Min length: The minimum length of a tracker (measured in number of frames) that a tracker must exist for before it is added to the tracker list. Increasing this value will mean new trackers are rejected if they do not track over the specified number of frames.

最小长度:一个跟踪的最小长度(帧数),它被添加到跟踪列表之前,必须存在一个跟踪。增加该值将意味着新的跟踪点被拒绝,如果他们不跟踪在指定的帧数。
