CNN features are of shape LCHW, where L is the number of layers that are aggregated, HW tells the spatial size and C represents the number of channels.

Dynamic Head [1] achieved state of the art when came out by combining scale aware attention(L dimension), spatial aware attention(HW dimension) and task aware attention(C dimension).
