What is sd-controlnet-depth?
sd-controlnet-depth is a specialized neural network structure designed to enhance Stable Diffusion's capabilities by incorporating depth information as a conditioning factor. This model enables precise control over image generation by utilizing depth maps, where black represents deep areas and white represents shallow areas in the scene. The model was trained on 3 million depth-image pairs generated using the Midas depth estimation system.
Implementation Details
The model integrates with Stable Diffusion v1-5 and uses a unique architecture that allows for conditional control while maintaining the base model's generation capabilities. It processes grayscale depth maps as input conditions and can be easily implemented using the diffusers library with minimal computational overhead.
