To clarify: your viewpoint is from a moving car, and you need to detect other moving cars?

Hi Monalisa,

If you read through the code in this example, you will notice that it uses an in-built function to detect people ("detectPeopleACF"). Once the detection of the object of interest is done, all that the tracking algorithm does is use a Kalman filter based approach to predict the position of the object in the next time instant. So I suppose you would have to replace the people detector algorithm with something that detects cars. There are a couple of ways to train your system to detect cars (or any object of interest). Refer to the following link that describes how it can be done in MATLAB:

Train a cascade classifier

I hope this helps.

Ragards,
