How to imlement operation?

Dear LIAGM,
Can the code below implement the operation? is it right ? I use this in the program, but find the Cost volume became Nan !

Thanks

Hi

I just wonder why you want to use correlation in the costvolume?
And as I remembered, this part of the code is to construct the costvolume.
The tmp_list contains N*N shifted feature map, and I am not sure what you want to correlate with?
Can you describe more clearly for the output of the function?

Regards,

Hi

I am not sure that the function of multiply can do the operation you want.
Maybe you can simply do some correlation operation in the channel dimension separately to make it become a scalar.
These are the suggestion I can give to you
