WHat's mean of bottom: 'rpn_bbox_inside_weights' in SmoothL1Loss layer

[Caffe_User]

Dear all,   I have a confusing point that in Faster RCNN layer configiure file,  like below defintion:

layer {

  name: "rpn_loss_bbox"

  type: "SmoothL1Loss"

  bottom: "rpn_bbox_pred"

  bottom: "rpn_bbox_targets"

  bottom: 'rpn_bbox_inside_weights' # ??

  bottom: 'rpn_bbox_outside_weights'  # ??

  top: "rpn_loss_bbox"

  loss_weight: 1

  smooth_l1_loss_param { sigma: 3.0 }

}

What's the meaning of  bottom: 'rpn_bbox_inside_weights' for SmoothL1Loss layer ?

Thanks you very much!

Hey,

Did you find the understanding behind usage of  bbox_inside_weights and  bbox_outside_weights in smoothL1Loss layer? It would be really helpful if you could guide me :)

Thank you
