Modumer: Modulating Transformer for Image Restoration
Keywords: Image restoration, Transformer block, Modulation design
Abstract: Image restoration aims to recover clean images from degraded versions. While Transformer-based approaches have achieved significant advancements in this field, they are limited by high complexity and their inability to capture omni-range dependencies, hindering their overall performance. In this work, we develop Modumer for effective and efficient image restoration by revisiting the Transformer block and Modulation design, which processes input through a convolutional block and projection layers, and fuses features via element-wise multiplication. Specifically, within each unit of Modumer, we integrate the cascaded Modulation design with the downsampled Transformer block to build the attention layers, enabling omni-kernel modulation and mapping inputs into high-dimensional feature spaces. Moreover, we introduce a bioinspired parameter-sharing mechanism to attention layers, which not only enhances efficiency but also improves performance. Additionally, a dual-domain feed-forward network strengthens the representational power of the model. Extensive experiments demonstrate that the proposed Modumer achieves state-of-the-art performance on ten different datasets for five image restoration tasks: image motion deblurring, image deraining, image dehazing, image desnowing, and low-light image enhancement. Furthermore, our model yields promising performance on all-in-one image restoration tasks.
