what does 'm' signify in the Kalman filter ?

[daraamer321]

I am trying to employ the Kalman filter in project for object tracking in case of occlusion. Your implementation is very good and seems it will work for me, however I don't get the significance of variable 'm' and how will it change after every frame. I am not clear about its use. Can you clarify for me . Thanks.

m is defined some lines before. It is simply the length of the measurement vector. For example, in the CTRV implementation of the Kalman Filter, you can see

# Lenth of the measurement
m = measurements.shape[1]

If you receive data continuously, you may write while True: and don't count anything.
