ComfyUI 36 Inpainting with Differential Diffusion Node - Workflow Included -Stable Diffusion
TLDRThis tutorial demonstrates the use of the Differential Diffusion node in the latest version of ComfyUI 36 for inpainting tasks in Stable Diffusion. The process involves creating a workflow with a new column for image loading and masking, using the Mask Editor for precise selection, and applying a Gaussian Blur for better results. The video showcases the effectiveness of the Differential Diffusion node in improving image inpainting, especially in handling complex details like hair and facial features. It also explores different selection methods for inpainting specific elements, such as changing a t-shirt color and transforming blue jeans to white, highlighting the significant visual improvements achieved with the node enabled.

Q & A
What is the differential diffusion node and how is it used in inpainting?
-The differential diffusion node is a feature in the latest version of ComfyUI that enhances inpainting by making the in-painted areas blend more seamlessly with the rest of the image. It is used by incorporating it into the inpainting workflow, which involves creating a mask to define the area to be inpainted.
How do you create an inpainting workflow in ComfyUI?
-An inpainting workflow in ComfyUI is created by adding a column between the loader and the sampler to load the image and define the mask for inpainting. This involves using the mask editor to draw the mask around the area that needs to be inpainted.
What is the purpose of the Gaussian Blur in the inpainting workflow?
-The Gaussian Blur in the inpainting workflow serves to smooth out the edges of the inpainted area, helping to create a more natural transition between the new and existing parts of the image.
How can you adjust the size of the cursor in the mask editor?
-The size of the cursor in the mask editor can be adjusted using the mouse wheel, allowing for precise drawing of the mask around the area to be inpainted.
Why might the initial inpainting result look distorted?
-The initial inpainting result might look distorted due to the lack of fine detail and accurate blending at the edges of the inpainted area, especially in complex areas like hair or facial features.
What benefit does the differential diffusion node bring to the inpainting process?
-The differential diffusion node improves the inpainting process by providing a more accurate and less distorted result. It helps in creating a smoother and more natural-looking inpainting, especially in areas with complex details.
How do you change the color of an object in the image using the inpainting workflow?
-To change the color of an object, you first change the prompt to describe the desired color and object. Then, you create a new mask in the mask editor to select the area of the object that needs to be color-changed, and apply the inpainting process with the differential diffusion node if necessary.
What is the 'some detector' mentioned in the script and how is it used?
-The 'some detector' is likely a feature within the mask editor that helps in automatically detecting and selecting a specific part of the image, such as a t-shirt. It is used by clicking on the desired area and adjusting the confidence level to ensure accurate selection.
Why might the edges of the inpainted area still have problems even after using the blur mask?
-Even with the blur mask, the edges of the inpainted area may still have problems due to the complexity of the original image or the accuracy of the mask. Fine details and transitions might not be perfectly matched, requiring further adjustments or additional inpainting steps.
How can you improve the result of inpainting a specific object like a t-shirt?
-To improve the result of inpainting a specific object like a t-shirt, you can use the some detector to accurately select the t-shirt area, adjust the confidence level for better detection, and then apply the inpainting process, optionally using the differential diffusion node for better blending.
What is the final step suggested in the script to improve the inpainting result further?
-The final step suggested in the script to improve the inpainting result further is to perform a second sampler step after applying the differential diffusion node. This can help in refining the details and removing any remaining issues around the edges or other areas of the inpainted object.
Outlines
🎨 In-Painting with Differential Diffusion Node
This paragraph introduces the use of a new feature in an image editing software: the differential diffusion node. It is highlighted as an excellent tool for in-painting, which is the process of filling in missing or selected parts of an image. The speaker demonstrates the process of creating a mask to define the area for in-painting, adjusting parameters like the Gaussian blur, and using the differential diffusion node to improve the results. The comparison before and after using the node shows a significant enhancement in image quality, particularly in the hairline and facial features, proving the effectiveness of the differential diffusion in creating a more natural and less distorted image.
👕 Color and Texture Adjustment with Advanced Selection Methods
In this paragraph, the focus shifts to changing the color and texture of specific elements in an image, such as a t-shirt. The speaker describes using different selection methods to accurately target the area of interest, including the use of a blur mask to refine the selection. The paragraph details the process of adjusting the image with and without the differential diffusion node, noting the challenges in achieving clean edges and the improvement in results when the node is engaged. The speaker also experiments with changing the color of jeans from blue to white, demonstrating the use of the software's selection tools and the impact of the differential diffusion node on the final image quality.
