camera intrinsic for citywalk

[ytoon]

Hi,
I appreciate your work. I find that camera intrinsic in citywalk.txt is [410, 410, 320, 180] (fx, fy, cx, cy). But the size of one processed image are [3, 528, 960] (c, h, w). To my knowledge, (cx, cy) should be half of (h, w) of image. How to set the camera intrinsic for citywalk_2000hr dataset?

Thank you for your interest in our work.

The city walking videos we downloaded is of resolution 640x360 ("worst" format if you are using youtube-dl).
If you want use different resolutions, you should provide corresponding intrinsics.

Thanks for your reply. It has solved my concern about (cx, cy) settings. I still have the question about (fx, fy). Why is (410, 410)?
