The gains of ,Mask R-CNN, over [27] come from using RoIAlign (+1.1 APbb ), multitask training (+0.9 APbb ), and ResNeXt-101 (+1.6 APbb ). ,Mask, Branch: Segmentation is a pixel-to-pixel task and we exploit the spatial layout of ,masks, by using an FCN. In Table 2e, we compare multi-layer perceptrons (MLP) and FCNs, using a ResNet-50-FPN backbone.
