implementing prior bounding boxes as keras layers? #71

Open BenMacKenzie opened 7 years ago

BenMacKenzie commented 7 years ago

is there any particular reason to implement the bounding box priors as a layer in the keras model? if i'm reading this correctly, it only ever gets used again during post-processing of the prediction. is it to 'auto-configure' the priors based on input size etc... by detecting input from previous layer?

@BenMacKenzie yep, it's for auto-configuring priors based on a layers' outputs.

Make PriorBox a keras layer, will it compute input gradient in backward?
