Implementation Details of rotate_roi_pooling_layer.cpp #42

Open Mypathissional opened 6 years ago

Hi all,

I am trying to re-implement the Rotate Roi Pooling Layer and I can't quite understand where the variables of AB,AC,ABAB,ACAC, ABAP,ACAP come from in the paper. The problem is that because of the additional checking condition with those variables , there is a very rare update.

Just trying to understand, any help is highly appreciated.

@Mypathissional Hi there, This condition is for border judging for a position, we cannot directly use the border to judge it. Only direction of the vector helps judging it.

@Mypathissional A simple geometric trick :)
