Tracktor is an OpenCV based object tracking software. The software is able to perform single-object tracking in noisy environments or multi-object tracking in clear environments. In addition to tracking multiple objects simultaneously, tracktor is also able to maintain individual identities. I have provided three example notebooks to help the user track objects in videos. Each example is provided because it shows how tracktor is able to solve various tracking related problems while maintaining individual identities.
This example shows how tracktor is able to track objects in noisy environments. The video shows tracking of a fish alone in a tank. A falcon tube is dropped in the tank creating ripples and bubbles in the water. Tracktor is able to track the focal fish despite these disturbances.
This example depicts multiple object tracking where objects to be tracked vary considerably in size. The female spider is about an order of magnitude (10x) larger than the male spider. In addition to tracking vastly differently sized objects simultaneously, this example also shows how individual identity is maintained despite disturbances. At 00:01:00 into the video, a human enters the frame to examine the web. Despite numerous contours satisfying the tracking conditions (seen in the tracked video as contours), tracktor is able to continue tracking focal spiders while successfully maintaining their identities.
This example consists of eight termits moving in a petridish. Tracktor is successfully able to track all eight termits while maintaining individual identities. In addition to tracking and identifying numerous objects, tracktor is also shown to maintain identity when termites touch each other (during trophallaxis).
Tracktor works on all operating systems (Windows, Linux and Mac). It is now available for installation as a Pip package. Use the line below in the the terminal / command prompt to install tracktor.
pip3 install git+https://github.com/vivekhsridhar/tracktor.git
This installs all dependencies except OpenCV. OpenCV needs to be installed separately. Additionally, I recommend installing jupyter notebook which is essential for running the example notebooks.
