how to cover my pixel coordinates into such coordinates to train my model

[hushunda]

the data is [frame id y x].
0 5 -1.59 0.93
10 5 -1.59 0.93
20 5 -1.59 0.93
30 5 -1.59 0.93
40 5 -1.59 0.93
50 5 -1.59 0.93
60 5 -1.59 0.93
70 5 -1.59 0.93
80 5 -1.59 0.93
90 5 -1.59 0.93
100 5 -1.59 0.93

but i don't know the x-y coordinates represent?

In your code, you calculate the value of x - y as relative coordinates, I don't understand the meaning of the x - y?
