comfyui中deforum

U-Net模型：ComfyUI的底层依赖Stable Diffusion，而去噪过程是由U-Net网络来完成的。U-Net是一种编码器-解码器结构，能够处理多尺度的特征表示。在ComfyUI中，去噪的每个步骤通过模型推理模块实现，这个模块会调用训练好的U-Net模型，逐步将噪声图像还原成有意义的图像。Cross Attention（交叉注意力）：交叉注意力机制在Stable Diffusion中尤为重要，它允许模型在生成过程中融入文本提示、图像、语义信息等条件。在ComfyUI中，这部分通过“文本提示”和“条件输入”节点实现。ComfyUI的可视化界面允许你调整和修改这些交叉注意力机制中的参数，例如文本提示的权重，这直接影响生成图像的内容。Skip Connection（跳跃连接）：跳跃连接是U-Net的核心部分，能够在不同尺度之间共享特征。这在ComfyUI的节点网络中表示为中间过程数据的流转。例如，你可以在不同的推理步骤中查看中间生成结果，并通过跳跃连接调整特定尺度上的生成效果。Switch（切换器）：在图中，切换器代表在去噪过程中的不同阶段对特征流的控制。在ComfyUI中，你可以通过修改模型的参数节点或自定义网络结构节点，对不同阶段的噪声去除策略进行微调。

This Page is an overview of the features and settings in the Deforum extension for the Automatic1111 Webui.If you are using the notebook in Google Colab,use this[guide](https://docs.google.com/document/d/1pEobUknMFMkn8F5TMsv8qRzamXX_75BShMMXV8IFslI/edit)for the overview of controls(This is also a good alternate reference for A1111 users as well).The Extension has a separate tab in the Webui after you install and restart.In it,there is another set of tabs for each section of Deforum.I'll be giving a breakdown of the controls,parameters and uses.Comparison videos were created by hithereai,thanks for putting together these great examplesI plan on adding techniques,more workflows and resources like masks and settings files.
