Question About Generate Ground Truth Permutation Matrix #19

Open wanghr-git opened 2 years ago

wanghr-git commented 2 years ago

@zorzi-s Hi! There are only the final segmented corner points in Ground Truth, and the number of these corner points is often much less than 256. How do we generate the Permutation Matrix of Ground Truth based on Ground Truth? Thank you😊

Hello, Brother. Do you know how to construct a permutation matrix？

How do you map points before constructing a permutation matrix？

It seems that map points is not ineed
