Uniform hypergraphs have a natural one-to-one correspondence to tensors. Inthis paper, we investigate the Estrada index and subgraph centrality of an$m$-uniform hypergraph $\mathcal{H}$ via the adjacency tensor. We establishsome bounds for the Estrada index and give expressions of the subgraphcentrality in terms of graph parameters of the multi-digraphs associated with$\mathcal{H}$. When $\mathcal{H}$ is $2$-uniform, the above Estrada index andsubgraph centrality are the Estrada index and subgraph centrality of a graph.
