need direction with optical flow about norfair

[bwithai]

Thank you so much for providing such beautiful tracker ❤️

I have done with my need by updating cv2.circle() to cv2.arrowedLine()

Hi @bwithai

The motion estimation function is used to estimate the movement of the camera, not the movement of the detections.

I'd like to ask you a question to make sure we understand your use case. Would you like to get a vector indicating the direction for each detection? Is the camera still, moving, or both?

Thank you so much for your prompt response dear @DiegoFernandezC ,

Yes I need direction of each detected object. my focus is on the moving object but it will be bonus if possible for both.

give me hint to draw a direction arrow rather then a line followed by point.

Once again thank you so much for your response.
