ControlNet 模型由 Lvmin Zhang、Anyi Rao、Maneesh Agrawala 在《Adding Conditional Control to Text-to-Image Diffusion Models》中提出。它透過對邊緣圖、深度圖、分割圖和姿態檢測關鍵點等附加輸入進行條件控制，從而對文字到影像的生成提供更高程度的控制。
論文摘要如下：
我們提出了 ControlNet，一種神經網路架構，用於為大型預訓練文字到影像擴散模型新增空間條件控制。ControlNet 鎖定生產就緒的大型擴散模型，並重用它們深度且魯棒的編碼層，這些編碼層經過數十億影像的預訓練，作為學習多種條件控制的強大骨幹。神經網路架構透過“零卷積”（零初始化卷積層）連線，這些卷積層引數從零開始逐步增長，確保不會有有害噪聲影響微調。我們測試了各種條件控制，例如邊緣、深度、分割、人體姿態等，結合 Stable Diffusion，使用單條件或多條件，帶提示或不帶提示。我們表明 ControlNet 的訓練對於小（<50k）和大（>1m）資料集都非常穩健。大量結果表明，ControlNet 可能有助於更廣泛地應用以控制影像擴散模型。
此模型由ishan24貢獻。❤️ 原始程式碼庫可在NVlabs/Sana找到，您可以在Efficient-Large-Model 的Hub 個人資料中找到官方 ControlNet 檢查點。
