adding another detection layer on conv3_3

[ghost]

Dear @mahyarnajibi and @po0ya, I was wondering if during implementation, have you guys experimented adding another detection layer at conv3_3 which has feat_stride: 4? Since wider face consists a lot of small faces. If yes, could you please share some insights? many many thanks.

Hey, feat_stride: 4 requires a higher resolution feature map than conv4_3, else we will be predicting two different values from the same location. Since conv4_3 feature map dimensions are 1/8 of the input's. Maybe a new module on conv3_3. I think we tried it and it didn't make that much of a difference. It's worthwhile to do an analysis to see what is "recall vs size" of the smallest scale detection module for gt boxes with dim less than 8 with and without the new module.
