Architecture dimension #35
Description
Hello everyone,
I would like to ask about the varifocalNet head architecture. As I understand, the output from feature pyramid has different levels and thus different dimensions. However, I read in the paper, you shown that the input dimension to the head is HxWx256. Is it the same for every levels? The outputs from feature pyramid with backbone resnet50 are (batch, 256, 52, 52), (batch, 256, 26, 26), (batch, 256, 13, 13), (batch, 256, 7, 7), (batch, 256, 4, 4) which mean that I need to upsample to HxW for every feature height and width?
I hope my question will get a reply :D. Have a good day and research.
