\caption{Typical outpainting results. The pairs of columns present the  latent features and the corresponding images for each method. LOTUS effectively achieves a rectangular FOV, whereas RePaint contains an obvious seam surround the FOV edges, and LOTUS* fails to outpaint the blank areas.}
%\textbf{(b)} Outpainting performance of LOTUS under varying mask sizes. OW denotes the outpainting window size, which decreases from top to bottom, representing increasingly challenging outpainting tasks. Blue tags indicate results generated by LOTUS. LOTUS effectively removes FOV edge-related artifacts and produces realistic outpainting across different condition sizes.}
