最近、CNNとトランスフォーマーに基づく画像復元の重要な進展がありました。しかし、多くの既存の研究は、IRタスクの特性を考慮せずに基本的なブロックの設計に焦点を当てています。このアプローチはパラメータ冗長性と不必要な計算をもたらし、画像復元の効率が妨げられます。そこで、著者らはLIRと呼ばれる軽量な画像復元ベースラインを提案しました。LIRは、局所およびグローバル残差接続に存在する劣化を取り除き、Adaptive FiltersとAttention Blocksから構成されるLightweight Adaptive Attention(LAA)ブロックを導入しています。これにより、LIRは一部のタスクで最先端モデルと比較可能な性能を達成しました。
