 # YOLO v7 + 各种tracker实现多目标跟踪
 
+****
+
+本人在写这个代码的时候, 没想到会有这么多人看到. 然而, 必须承认我这份代码是以尽量整合为目的, 加了我自己的理解, 所以有的部分也许和原论文有出入, 导致效果不一定是最好的.
+
+为此, 给大家推荐一个成熟的repo: (https://github.com/mikel-brostrom/yolo_tracking)[https://github.com/mikel-brostrom/yolo_tracking]
+
+我这个代码大家可以作为学习之用, 也就是熟悉MOT的流程. 如果追求更好的效果, 我建议采纳更成熟的那些.
+
+我会不断听取大家的问题和建议, 希望和大家一起学习!

 ## 0. 近期更新
 
+**2023.10.24**: 对于botsort(`tracker/botsort.py line 358`)和bytetrack(`tracker/bytetrack.py line 89`), 在低置信度检测列表初始化, 改正原有错误 (原本写错了, 写的用`det_high`初始化). 
+
 **2023.9.16**: 对于`track_demo.py`, 由于`yolov7`的`non_maximum_supress`函数中已经对类别做了筛选, 因此删去了主程序中类别计算的部分, 并修复了一些小bug  
 
 **2023.5.6[大更新]**: 对于v5, v7, 改变前处理和后处理方式(采用原有方式), ***解决了部分边界框近大远小的bug, 边界框更加精确***. 此外, 对于v8, 弃用了resize步骤, 直接推理.
