Webb24 dec. 2024 · Based on this observation, we propose a simplification of the non-local block, which explicitly learns global context other than pairwise relations. The resulting block, called the global context (GC) block, consumes significantly less computation than the non-local block but performs with the same accuracy on several important tasks. WebbIn this paper, in order to balance the accuracy and computational complexity of non-local enhancement, the non-local operation is simplified based on local importance-based pooling, which can dynamically extract discriminative features during the down-sampling process by learning adaptive weights.
