Tracking Pedestrians from a Moving Car

I am using the example code for tracking pedestrian from a moving car (https://www.mathworks.com/help/vision/examples/tracking-pedestrians-from-a-moving-car.html) with different video. In this code an auxiliary file named "pedScaleTable.mat" is used that helps to determine the size of the pedestrian. I want to create this file for my own video. How can I create this file?

Hello Pallavi,

Do you have a reference video with no pedestrians in it?

If yes, then it will be easy to find the size of pedestrians.

Try using this approach:

Get all the frames in real time and subtract each of them from their respective reference frame from reference video.

    function frame = readFrame()
        frame = step(obj.reader);
    end

From the difference, You will get some blobs. Use regionprops() to detect the area of those blobs. It will give the idea of their size.

I hope it will be useful.

Thank you very much for this prompt reply. I have a doubt in your answer. Are you asking for the video same as my example video without pedestrian?

[MathReallyWorks]

Yes. That is the reference video.

Okay. Thanks a lot.
