The usage of upsample #121

There is such a paragraph in segnet_sun.prototxt: layer { name: "upsample5" type: "Upsample" bottom: "pool5" bottom: "pool5_mask" top: "pool5_D" upsample_param { scale: 2 upsample_h: 23 upsample_w: 30 } } Why there are 2 bottom?When I change to one bottom,it will report an error: Check failed: ExactNumBottomBlobs() == bottom.size() (2 vs. 1) Upsample Layer takes 2 bottom blob(s) as input. Why must have 2 bottom? I just want to enlarge the source image.

int ExactNumBottomBlobs() const { return 2; } ; one for feature maps, and one for the max-pooling indeices;
