Hello !!! Thank you for your open source !!! It's an amazing job!

But when I test on my devices， the frame rate is only 30Hz.
My operating devices are davis346， NVIDIA GeForce GTX 1050, and Core™ i5-7300HQ CPU @ 2.50GHz × 4 .

It may be caused by different equipment.
But It is much lower than 250 Hz as the paper said.
So I want to know the possible reasons for the lower frame rate.

Thanks a ton!

Hi,

Thanks for outsourcing code. Very useful
Do you have python version of code? Thanks

Hello， I'm here again.
I use the public dataset(shapes_6dof ) to test the OF accuracy. I meet two questions:

1. The data structure of optical_flow is "32FC2", Does the numerical value on each pixel mean the optical flow velocity or the relative increment of the pixel displacement at the next frame？ What is the unit of the value?

2. I added the camera calibration file（as followed）
   `%YAML:1.0

imageWidth: 240
imageHeight: 180
camera_matrix: !!opencv-matrix
rows: 3
cols: 3
dt: d
data:

But there were some problems：

When I canceled the calibration file, it looked normal：

Looking forward to your reply！
Thanks a ton！
