Multi-object tracking with dlib

https://www.pyimagesearch.com/2018/10/29/multi-object-tracking-with-dlib/

【调试代码时遇到问题】

Boost.Python.ArgumentError for dlib.rectangle #545

File "E:/code/traking/multiobject-tracking-dlib/multi_object_tracking_slow.py", line 112, in <module>
    rect = dlib.rectangle(startX, startY, endX, endY)
Boost.Python.ArgumentError: Python argument types in
    rectangle.__init__(rectangle, numpy.int32, numpy.int32, numpy.int32, numpy.int32)
did not match C++ signature:
    __init__(struct _object * __ptr64, long left, long top, long right, long bottom)
    __init__(struct _object * __ptr64)

【暂时解决方案】转化数据类型

https://github.com/davisking/dlib/issues/545

rect = dlib.rectangle(int(startX), int(startY), int(endX), int(endY))

AttributeError: module 'cv2.cv2' has no attribute 'Tracker_create'

【解决方案】需要安装opencv-contrib-python

目标跟踪的过程是怎样的？

• 获取目标检测的初始化集合（例如边界框坐标的输入集合）
• 为每一个初始检测对象创建唯一的ID.
• 当这些检测对象在视频帧间移动时跟踪它们，即保持它们分配的ID不变。

Object tracking is the process of:

1. Taking an initial set of object detections (such as an input set of bounding box coordinates)
2. Creating a unique ID for each of the initial detections
3. And then tracking each of the objects as they move around frames in a video, maintaining the assignment of unique IDs

理想的目标跟踪算法是怎样的？

• 只需要对象检测阶段一次（即，当最初检测到对象时）
• 将非常快，比运行实际的对象检测器快得多
• 当被跟踪的对象“消失”或移动到视频帧的边界之外时能够处理
• 在遮挡时稳定检测
• 能够拾取在帧之间“丢失”的对象

An ideal object tracking algorithm will:

• Only require the object detection phase once (i.e., when the object is initially detected)
• Will be extremely fast — much faster than running the actual object detector itself
• Be able to handle when the tracked object “disappears” or moves outside the boundaries of the video frame
• Be robust to occlusion
• Be able to pick up objects it has “lost” in between frames
