question about step (3)

[lifeiove]

Thank you for your sharing！ My question is, the change about step (3) "Getting the center_features of each default box" is also in train.prototxt? The param "num_output" about VOC2007 equals (20+1)*3=63. what about 64?

@lifeiove The step (3) refers to that each anchor should be represented by a vector with the same dimension as the center_features (you should set this parameter in train.prototxt). So, the num_output of fc7_norm_center_mbox_conf_new equals anchors_number * center_features(4*16).
