What does depth-wise pixel means？

[ss2lyf]

We note that in the Depth Map Validation, end point error (EPE), > 1 pixel error and > 3 pixel error are used to demonstrate the capacity of BlendedMVS dataset. However, what does depth-wise pixel means? Is it simply the difference values between the depth map and the ground truth depth map?

The depth-wise pixel is measured by the depth interval. For example, the depth interval of the view is 2.5mm, the GT depth is 100mm, and the estimated depth is 110mm. Then the EPE is (110 - 100) / 2.5 = 4 pixels.

For the cam.txt files in BlendedMVS like this:

1.21079 0.00412819 128.0 1.7392

Is the depth interval 0.00412819?

I am also wondering what does 1.21079 0.00412819 128.0 1.7392 in the last row mean?
