[CVPR 2022] RestoreFormer: High-Quality Blind Face Restoration from Undegraded Key-Value Pairs
RestoreFormer tends to explore fully-spatial attentions to model contextual information and surpasses existing works that use local operators. It has several benefits compared to prior arts. First, it incorporates a multi-head coross-attention layer to learn fully-spatial interations between corrupted queries and high-quality key-value pairs. Second, the key-value pairs in RestoreFormer are sampled from a reconstruction-oriented high-quality dictionary, whose elements are rich in high-quality facial features specifically aimed for face reconstruction.
