Frequency Domain Hierarchical Vision Transformer-based Perceptual Loss

This project focuses on improving image processing tasks, such as super-resolution or image restoration, by employing a novel feature comparison method. It leverages a Hierarchical Vision Transformer to extract multi-scale feature representations from images. These features capture both local and global information at various levels of abstraction. Crucially, these extracted features are then transformed into the frequency domain, likely via a Fast Fourier Transform (FFT) or similar method. The comparison between the generated image and the target image occurs in this frequency space. By analyzing differences in magnitude and/or phase across different frequency bands, the model can better understand and rectify discrepancies in texture, detail, and overall structure. This approach aims to produce perceptually superior results by guiding the model to reconstruct images that are more aligned with the frequency characteristics of the target, leading to improved visual quality, especially in terms of sharpness and fine-grained details.
