About the parameters "eig_val" and "eig_vec"

[ZhWL123456]

In the file CornerNet ”/db/coco.py“, there are parameters "self.eig_val" and eig_vec, I know they mean eigenvalue and eigenvector. But i dont know the way to count them in our own dataset. Can anyone tell me how to count the eigenvalue and eigenvector of the pic's rgb values? I dont know how to trainsform they to a square matrix, and i think only square matrix have eigenvalue and eigenvector. Thanks for helping!

I want to know how to compute these parameters, too.

Any update on this? Are the eigen values from COCO dataset? @princeton-vl @heilaw
