Freqformer Transformer tackles image demoiréing with frequency decomposition

Researchers have introduced Freqformer, a novel Transformer-based framework designed to address the challenging task of image demoiréing. This method effectively decomposes moiré patterns into distinct high-frequency textures and low-frequency color distortions, processing them through a dual-branch architecture. A key innovation is the learnable Frequency Composition Transform (FCT) module, which adaptively fuses these frequency-specific outputs for high-fidelity reconstruction. Additionally, a Spatial-Aware Channel Attention (SA-CA) module refines moiré-sensitive regions by enhancing spatial dependencies and inter-channel information. AI
