Beware of Aliases -- Signal Preservation is Crucial for Robust Image Restoration
Researchers have introduced BOA-Restormer, a novel transformer-based model designed for image restoration. This model addresses the issue of aliases, which can arise during downsampling and upsampling operations in standard architectures, potentially compromising robustness for higher performance metrics. By incorporating alias-free paths, partly through frequency domain operations, BOA-Restormer aims to enhance model robustness without significantly sacrificing restoration quality. AI
