所有的图片均被转换为JPEG格式，保存成6为数字文件名（如000001.jpg）。检测结果和标记文件用CSV格式保存，每一行表是一个物体，拥有9个值如表5所示。

TABLE 5: Data format for the input and output files, both for detection (DET) and annotation/ground truth (GT)files.

Position	Name	Description
1	Frame number	Indicate at which frame the object is present
2	Identity number	Each pedestrian trajectory is identified by a unique ID (−1 for detections)
3	Bounding box	left Coordinate of the top-left corner of the pedestrian bounding box
4	Bounding box	top Coordinate of the top-left corner of the pedestrian bounding box
5	Bounding box	width Width in pixels of the pedestrian bounding box
6	Bounding box	height Height in pixels of the pedestrian bounding box
7	Confidence score	DET: Indicates how confident the detector is that this instance is a pedestrian.GT: It acts as a flag whether the entry is to be considered (1) or ignored (0).
8	Class	GT: Indicates the type of object annotated
9	Visibility	GT: Visibility ratio, a number between 0 and 1 that says how much of that object is visible. Can be due

第一个数字表示物体出现在哪一帧中，第二个数字表示其出现在哪一个轨迹中，值为-1时表是不属于任何一个轨迹。后面的四个数表是bounding box的位置,每一个物体只属于一个轨迹。位置标记以左上角为标记点，4个数字分别表示左上角的位置，高度以及宽度。然后后面是一个单独的数字，表示一个概率分数，最后两个数字一个代表分类，一个代表可见程度.
这是其中的一个用例：
