Supplemental Material for Stochastic Window Transformer for Image Restoration

Small patch with global attention leads to the broken translation invariance and loss of locality. Under this setting, the broken translation invariance derives from two aspects. Figure 1: The illustration of context of the shifted window strategy and sliding window strategy. T aking expectation boosts performance. PSNR [7] and SSIM [17] based on the luminance channel, i.e., Y channel of YCbCr space.
