The architecture of the networks: a the HRNetV2 [3]; b the proposed HR-MPF network consists of three stages (blue boxes). This is a multi-scale progressive fusion network with boosted modules incorporated. The fusion is implemented from high-to-low or low-to-high resolution so that the spatial and context information of features of all resolutions are fully engaged. The size of the feature map in each path is also marked
