the implementation of location map loss and delta map loss

[MengHao666]

Hi， thanks for your great work.

I found in wrappers.py , the size of location map and delta map are equally 1X32X32X21X3,
and the size of 2D heatmap is 1X32X32X21,
but the loss is caculated as follows in you paper

But I am quite confused how to do "element-wise matrix product " between variables with size of 1x32X32X21X3 and 1X32X32X21 respectively. Could u give more details?

It's done for each channel of D.

Do u mean first transfer 1X32X32X21 to 1X32X32X21X3 first using tile ?

yes
