ComfyUI Face Detailer (by ThinkDiffusion)

How cool is face detailer?

What is Face Detailer?

Dr. Lt. Data, the creator of the ComfyUI Manager, is also responsible for developing the ComfyUI Face Detailer. This node can easily recognize and enhance faces, making it ideal for restoring characters' faces in photos, movies, and animations. The Face Detailer employs a comprehensive processing pipeline for face detection and enhancement, offering user-adjustable settings for targeted effects.

For further improvement, the 4x UltraSharp Model excels at upscaling images, significantly increasing resolution while maintaining clarity, enhancing details, and reducing artifacts. This makes it perfect for producing high-resolution stills and moving images.

Combined, these tools provide a powerful arsenal for enhancing the visual quality of photos, movies, and animations, especially when facial adjustments or overall clarity improvements are required. The ComfyUI Impact Pack includes a collection of bespoke nodes like the Detector, Detailer, Upscaler, and Pipe, streamlining and simplifying picture enhancement with advanced tools.

Significant Features

Basic Auto Face Detection and Refinement

Make use of FaceDetailer for simple, automated face improvement and detection. This function uses high-resolution synthesis to revive lost details, making it ideal for repairing faces affected by low resolution. One sophisticated method for detecting faces and improving images is FaceDetailer, which combines the Detector and Detailer nodes. The mask output color-codes the regions that need improvement, making the difference between the two sides stand out.

2Pass Refine

Take a two-step method by utilizing two FaceDetailers to repair severely damaged faces. With this configuration, you can easily configure different common inputs and streamline workflow modification using FaceDetailer (pipe). While selective dilatation aids in including neighbouring regions for thorough face reconstruction, the first pass concentrates on recreating the fundamental outline with moderate settings and resolution.

Face Bbox + Person Silhouette Segmentation

When enhancing a person's face, the following combination effectively eliminates distortion caused by the backdrop. This solution uses BBoxDetectorForEach for face detection and SAMDetectorCombined for segment identification. It guarantees that the detailed enhancements will be exactly aligned with the face contours and won't affect the surrounding portions of the image.

Getting Started using ComfyUI powered by ThinkDiffusion 

This is the default workflow, generating an image which shows a simple result.

Generating an image using default workflow may lead to unexpected results such as deformities, facial artifacts and others. With the help of Face Detailer, the generated image will be fixed, fine tuned, upscaled and enhanced. Before you can work with Face Detailer, there are certain Custom Nodes and Models that need to be installed.

Face Detailer (pipe)

Installation

Below are the list that needs to be installed:

• ComfyUI Impact Pack

• Ultralytics Models

• https://github.com/ultralytics/assets/releases - download the additional model yolov8m-seg.pt

1. By default, there is no Face Detailer (pipe) node in ComfyUI. All you need to do is install it using a manager. Go to the Manager at the right panel and click the Install Custom Nodes once the Manager Menu appears.

1. Search the “impact” word in the search box and choose ComfyUI Impact Pack and click the Install. Face Detailer node belongs to the Impact Pack.

1. Don’t forget to restart the ComfyUI machine for the newly installed custom node to take effect. If the node is not yet available in the node list even though the RESTART was already clicked, just click the stop button, and relaunch the machine.

1. You need to install the models too. To get them you need to go to Install Models from the Manager.

1. You can add more models from the list below. Just pick an ultralytics for face and person and click the Install button.

1. You can see the models that were installed on the right. Don’t forget to click close and click Restart UI.

1. Click Restart UI or Click the Stop and Relaunch ComfyUI machine in order for the new models to take effect.

2. Additional Model. You need to download the yolov8m-seg.pt from https://github.com/ultralytics/assets/releases and upload to the My Files section of ThinkDiffusion. Just click the My Files icon if the upload panel is hidden. Navigate to the comfyui/models/ultralytics/segm/ folder and upload the file in the segm folder. If the folder is not available, just create the required folder to set up the directory correctly. Restart the ComfyUI machine for newly uploaded model to take effect.

How does it work?

1. You can now launch an instance of ComfyUI, and you will see the default workflow.

2. The nodes below are from the Impact Pack which are useful for the Face Detailer (pipe).

• ToBasicPipe

• BasicPipe -> DetailerPipe

• UltralyticsDetectorProvider

• KSampler (pipe)

• FaceDetailer (pipe)

• SAMLoader (Impact)

1. This is an arrangement of the Impact Pack nodes for the face detailer (pipe). Observe the placement and connect them according to the input and output names. Read the bulleted info before running the prompt.

• Take note that the KSampler was replaced by a new node named KSampler (Pipe).

• Use the base model Epic Realism which is good for generating images of realistic people.

• Use the face_yolov8m.pt for UltralyticsDetectorProvider node. BBOX_DETECTOR

• Use the person_yolov8m-seg.pt for UltralyticsDetectorProvider node. SEGM_DETECTOR

• Use the sam_vit_b_01ec64.pth for SAM Loader node.

Face Detailer + Ultimate SD Upscale

Download workflow here: Face Detailer with Upscale

Installation

Below are the list that needs to be installed:

• ComfyUI Impact Pack

• Ultimate SD Upscale

• https://openmodeldb.info/ - download the following upscale model: 4x_foolhardy_Remacri.pth, 4x-ClearRealityV1.pth, 4xNomos8HAT-L_otf.pth or you can choose any you like.

1. By default, there is no Face Detailer node in ComfyUI. All you need to do is to follow the installation  Step 1 , 2, 3 here for ComfyUI  Impact Pack.

2. For Ultimate SD Upscale custom node, follow the process below:

1. Search for Ultimate in the search box, choose the UltimateSDUpscale and click Install.

1. Don’t forget to restart the ComfyUI machine for the newly installed custom node to take effect. If the node is not yet available in the node list even though the RESTART was already clicked, just click the stop button, and relaunch the machine. 

1. To use the downloaded Upscale model files, upload them to ThinkDiffusion as you can see in the right panel. Just click the My Files icon if the upload panel is hidden. Navigate to the comfyui/models/RealESRGAN directory and upload the file in the RealESRGAN folder. If the folder is not available, just create the required folder to set up the directory correctly.

Summary

ComfyUI enthusiasts use the Face Detailer as an essential node. There is a good comparison between the three tested workflows for face detailers, and you can decide which workflow you prefer.  Face Detailer without a pipe is a basic workflow to start with, but the problem is that the output is not being upscaled. While the workflow with Face Detailer (pipe) generates a better output and is more detailed than an ordinary one. Having a workflow with an upscale model works great too. If you can create a workflow with a pipe and an ultimate SD upscaler, the output is far superior. 

Pretty Comfy, Right?

Any of our workflows including the above can run on a local version of SD but if you’re having issues with installation or slow hardware, you can try any of these workflows on a more powerful GPU in your browser with ThinkDiffusion.
