Sdsoc optical flow vectors size problem

[YasinKaganTaskin]

I'm try to build a point tracker using optical flow example inside the reVision 2018.3 image for zcu104.

I record the flow_x and flow_y variables in to .csv file to better investigation then i realise the size of vectors is not correct. I have read the xapp1300 and ug1233. The error is way beyond the sub-pixel accuracy. I am using well textured images to make sure about that.

Is this function (DenseNonPyrLKOpticalFlow) is just for illustration ? Is there any way to correct these error.

Thanks in advance.

@YasinKaganTaskin , Few Questions:

• What is your reference output with which you are computing?
• What's the input image size and Window size you used?
• Can you share the input frames for us to be able to reproduce the issue.
