DemoFusion
This pipeline is the official implementation of DemoFusion: Democratising High-Resolution Image Generation With No $$$. This script was contributed by RuoyiDu and the notebook byParagEkbote.
Parameters:
view_batch_size (int, defaults to 16): The batch size for multiple denoising paths. Typically, a larger batch size can result in higher efficiency but comes with increased GPU memory requirements.
stride (int, defaults to 64): The stride of moving local patches. A smaller stride is better for alleviating seam issues, but it also introduces additional computational overhead and inference time.
cosine_scale_1 (float, defaults to 3): Control the strength of skip-residual. For specific impacts, please refer to Appendix C in the DemoFusion paper.
cosine_scale_2 (float, defaults to 1): Control the strength of dilated sampling. For specific impacts, please refer to Appendix C in the DemoFusion paper.
cosine_scale_3 (float, defaults to 1): Control the strength of the Gaussian filter. For specific impacts, please refer to Appendix C in the DemoFusion paper.
sigma (float, defaults to 1): The standard value of the Gaussian filter. Larger sigma promotes the global guidance of dilated sampling, but has the potential of over-smoothing.
multi_decoder (bool, defaults to True): Determine whether to use a tiled decoder. Generally, when the resolution exceeds 3072x3072, a tiled decoder becomes necessary.
show_image (bool, defaults to False): Determine whether to show intermediate results during generation.
