ComfyUI Extension: DepthFM IN COMFYUI

DepthFM IN COMFYUI Introduction

ComfyUI-DepthFM is an unofficial implementation of the DepthFM model for ComfyUI. DepthFM, developed by the CompVis Group at LMU Munich, is a state-of-the-art, versatile, and fast monocular depth estimation model. This extension allows AI artists to generate realistic depth maps from both images and videos efficiently. By integrating DepthFM into ComfyUI, you can enhance your creative projects with accurate depth information, which is essential for tasks like 3D modeling, virtual reality, and advanced image editing.

How DepthFM IN COMFYUI Works

ComfyUI-DepthFM leverages the DepthFM model to estimate depth from a single image or a sequence of images (videos). Depth estimation is the process of determining the distance of objects from the camera in a scene. DepthFM uses a technique called flow matching, which maps the input image directly to a depth map, bypassing the need for multiple inference steps. This makes the process faster and more efficient.

Imagine you have a photograph, and you want to understand how far each object in the photo is from the camera. ComfyUI-DepthFM can analyze the photo and create a depth map, where different shades represent different distances. This depth map can then be used in various creative applications, such as adding realistic shadows, creating 3D effects, or enhancing virtual reality experiences.

DepthFM IN COMFYUI Features

DepthFM ModelLoader

• Description: This feature allows you to load the DepthFM model into ComfyUI.
• Customization: You need to manually download the DepthFM model file (depthfm-v1.ckpt) and place it in the /ComfyUI/models/depthfm directory.
• Usage: This is the first step to start using ComfyUI-DepthFM. Without loading the model, other features won't work.

Single Image Depth Estimation

• Description: This feature estimates the depth of a single image.
• Customization:
• Steps: The number of steps for depth estimation. For general use, 2-4 steps are recommended. For more detailed results, 10 steps are suggested.
• Ensemble Size: The number of models used to improve accuracy. Higher values yield more accurate results but require more memory. A value of 2-4 is generally recommended.
• Image Size: The image dimensions should be multiples of 64. - Example: If you have a portrait photo and want to create a depth map, you can use this feature to get a detailed depth representation of the image.

Multi-Image/Video Depth Estimation

• Description: This feature supports depth estimation for multiple images or videos.
• Customization:
• Steps: Similar to single image depth estimation, 2-4 steps for general use and 10 steps for detailed results.
• Ensemble Size: Same as single image depth estimation.
• Image/Video Size: The dimensions should be multiples of 64. - Example: If you have a video clip and want to generate a depth map for each frame, this feature will process the entire video and provide depth information for every frame.

DepthFM IN COMFYUI Models

Currently, ComfyUI-DepthFM uses the depthfm-v1 model. This model is designed to provide fast and accurate depth estimation for both images and videos. The model can be downloaded from .

When to Use the Model

• Single Image Projects: Use the model for projects that involve single images, such as portrait enhancements or single-frame 3D effects.
• Video Projects: Use the model for video projects where you need depth information for each frame, such as in virtual reality or advanced video editing.

What's New with DepthFM IN COMFYUI

Version 1.0

• Release Date: March 22, 2024
• New Features:
• Support for both image and video depth estimation.
• Initial project creation and setup. These updates are significant as they expand the capabilities of ComfyUI-DepthFM, allowing AI artists to work with both static and dynamic content seamlessly.

Troubleshooting DepthFM IN COMFYUI

Common Issues and Solutions

1. Model Not Loading:

• Solution: Ensure that the depthfm-v1.ckpt file is placed in the /ComfyUI/models/depthfm directory.

2. Image/Video Size Error:

• Solution: Make sure the dimensions of your images or videos are multiples of 64.

3. Out of Memory Errors:

• Solution: Reduce the ensemble_size or the resolution of your images/videos.

Frequently Asked Questions

• Q: Can I use ComfyUI-DepthFM for real-time applications?
• A: While ComfyUI-DepthFM is efficient, it may not be suitable for real-time applications due to processing time requirements.
• Q: What is the best ensemble size for high accuracy?
• A: An ensemble size of 2-4 is generally recommended for a good balance between accuracy and memory usage.
