How to add “Tracker” in openCV python 2.7

Question

I’m working with python 2.7 and opencv 3.1 I want to run a code for tracking objects by this:

import cv2
import sys

if __name__ == \'__main__\' :

    # Set

I think the easiest and fastest method is to install via the .whl files. @foobar gives the answer in the post @kyjanond links to, but you can obtain the .whl files from the following links.

OpenCV: https://pypi.python.org/pypi/opencv-python/3.3.0.10

OpenCV Contrib: https://pypi.python.org/pypi/opencv-contrib-python/3.3.0.10

I installed OpenCV 3.3.0 on Python 2.7, so I downloaded:

• opencv_python-3.3.0.10-cp27-cp27m-win32.whl
• opencv_contrib_python-3.3.0.10-cp27-cp27m-win32.whl

To install, I ran:

• python -m pip install opencv_python-3.3.0.10-cp27-cp27m-win32.whl
• python -m pip install opencv_contrib_python-3.3.0.10-cp27-cp27m-win32.whl

This worked, but in the updated version of OpenCV, the way the tracker functions are called have changed.

The original code in the GitHub repository was:

---

tracker_types = ['BOOSTING', 'MIL','KCF', 'TLD', 'MEDIANFLOW', 'GOTURN']

tracker_type = tracker_types[1]

tracker = cv2.Tracker_create(tracker_type)

---

I changed this to

---

tracker_types = ['BOOSTING', 'MIL','KCF', 'TLD', 'MEDIANFLOW', 'GOTURN']

tracker_type = tracker_types[1]

if tracker_type == tracker_types[0]:
    tracker = cv2.TrackerBoosting_create()
elif tracker_type == tracker_types[1]:
    tracker = cv2.TrackerMIL_create()
elif tracker_type == tracker_types[2]:
    tracker = cv2.TrackerKCF_create()
elif tracker_type == tracker_types[3]:
    tracker = cv2.TrackerTLD_create()
elif tracker_type == tracker_types[4]:
    tracker = cv2.TrackerMedianFlow_create()
elif tracker_type == tracker_types[5]:
    tracker = cv2.TrackerGOTURN_create()

This approach seemed to work well for me.
