openaccess.thecvf.comFeature extraction. We extract a 4096-dimensional fea-ture vector from each region proposal using the Caffe [21] implementation of the CNN described by Krizhevsky et al. [22]. Features are computed by forward propagating a mean-subtracted 227 227 RGB image through five con-volutional layers and two fully connected layers. We refer
