ControlNet 模型由 Lvmin Zhang、Anyi Rao、Maneesh Agrawala 在《Adding Conditional Control to Text-to-Image Diffusion Models》中提出。它通过对边缘图、深度图、分割图和姿态检测关键点等附加输入进行条件控制，从而对文本到图像的生成提供更高程度的控制。
论文摘要如下：
我们提出了 ControlNet，一种神经网络架构，用于为大型预训练文本到图像扩散模型添加空间条件控制。ControlNet 锁定生产就绪的大型扩散模型，并重用它们深度且鲁棒的编码层，这些编码层经过数十亿图像的预训练，作为学习多种条件控制的强大骨干。神经网络架构通过“零卷积”（零初始化卷积层）连接，这些卷积层参数从零开始逐步增长，确保不会有有害噪声影响微调。我们测试了各种条件控制，例如边缘、深度、分割、人体姿态等，结合 Stable Diffusion，使用单条件或多条件，带提示或不带提示。我们表明 ControlNet 的训练对于小（<50k）和大（>1m）数据集都非常稳健。大量结果表明，ControlNet 可能有助于更广泛地应用以控制图像扩散模型。
