(a) Parallel feature integration architecture of HED [4]; (b) bottom-up feature integration which brings abstract semantics to detailed features [6]; (c) the linear span network proposed by Liu et al. [10] based on linear span theory to enrich the feature fusion; (d) hierarchical feature integration mechanism [8].
