所有的圖片均被轉換為JPEG格式，儲存成6為數字檔名（如000001.jpg）。檢測結果和標記檔案用CSV格式儲存，每一行表是一個物體，擁有9個值如表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 |
第一個數字表示物體出現在哪一幀中，第二個數字表示其出現在哪一個軌跡中，值為-1時表是不屬於任何一個軌跡。後面的四個數表是bounding box的位置,每一個物體只屬於一個軌跡。位置標記以左上角為標記點，4個數字分別表示左上角的位置，高度以及寬度。然後後面是一個單獨的數字，表示一個概率分數，最後兩個數字一個代表分類，一個代表可見程度.
這是其中的一個用例：
