In this video 📝 we are going to take a look at how to do easy object tracking with a Kalman filter in OpenCV. First of all, we need to detect the objects, set up our tracker with the Kalman filter, and then we can do tracking on a video sequence. In the end, we will see the results for the tracked objects.

So something to add would be some algorithms that could *remember* a previous ID of a person, and reassign it to that same person when obstruction happens?

[@prestonmcomber9895]

Where does the Kalman Filtering come into play? This is a great video on how to use tf-centernet, but I am having a hard time seeing where the filtering occurs. By Kalman filter, I mean a filter that could use system dynamics to track an object after an occlusion by varying the Kalman gain based on the propagation of uncertainty in measurements vs estimates. In the beginning of the video, you mentioned we would pass the bounding box into the Kalman filter. Where in the code do we do this?

[@wayneferguson2174]

If you dig into the code a bit you'll see that the sort.py file uses filterpy.kalman. The line res = sort.update(dets) updates the state vector with the observed box

[@chinmayganguly457]

if 0 is for people, what is the number for cars and bikes? this object tracker is very specific, i'd like to detect and track cars and other vehicles too

[@rishabhgarg3979]

Hey Nico, I love your tutorials. Just a quick question, How to track a person with specify color shirt? can you share the code or make a video, it would be helpful.

[@8eck]

3d deepsort would be cool. With proper stereo cameras setup i think it is possible. What do you think?

[@andreaslanter8182]

Hey;
Thanks for the video!! I have some trouble with the last step: create the video out of the images. My mp4 file is an empty file, and I don't know where the fault is. Can you help me?

[@eliramirez9376]

Hello, have you a tutorial for beginners in computer vision?

[@NicolaiAI]

Yeah! My computer vision playlist here on the channel will help u from scratch

[@daisy-iw2nf]

id's change when detection. How I make id the same for each person.

[@aisearch6747]

what is min_hits in Sort class ?

[@rutho.6282]

how do you trace an object's path?

[@NicolaiAI]

U can basically just append the centers of the tracked bboxes to a list

[@rishabraina8917]

Hi Nicolai...
Which yolo version is used for object detection purpose?

[@anirudhyadav-hr5zu]

yolov8 - ultralytics

[@xtu373]

make next video on advanced ai chatbot

[@NicolaiAI]

Will look into it!
