Figure 2. Proposed MoCE-IR framework. Despite recent advances in MoE-based image restoration [57, 62, 63], inconsistent expert behavior—where some experts over-generalize while others underperform—limits their computational efficiency. We address this through complexity experts: flexible blocks with varying computational capacity and receptive fields. Our MoCE-IR employs an asymmetric encoder-decoder architecture where each decoder block contains a mixture-of-complexity-experts layer for adaptive capacity routing.
