Some Utils for ComfyUI

Notice: The face detection node depends on TensorFlow 2.17, which is now outdated and may cause compatibility issues. Therefore, it is no longer installed by default. If you need to use this node, please install it manually. Users who have previously installed this library are not affected.

LoadImageWithSwitch

Modified the official LoadImage node by adding a switch. When turned off, it will not load the image.

LoadImageMaskWithSwitch

Modified the official LoadImageMask node by adding a switch. When turned off, it will not load the image to mask.

LoadImageWithoutListDir

When there are a lot of images in the input directory, loading image with os.listdir can be slow. This node avoids using os.listdir to improve performance.

LoadImageMaskWithoutListDir

When there are a lot of images in the input directory, loading image as Mask with os.listdir can be slow. This node avoids using os.listdir to improve performance.

ImageCompositeMaskedWithSwitch

Modified the official ImageCompositeMasked node by adding a switch. When turned off, it will return the destination image directly.

ImageCompositeMaskedOneByOne

Modified the official ImageCompositeMasked node to process images one by one, instead of processing an entire batch at once. In video scenarios, processing in a batch may require a significant amount of memory, but this method helps reduce memory usage.

ImageBatchOneOrMore

This node can input one or more images, the limit is six. It expands the functionality of the official ImageBatch node from two to multiple images.

ImageConcatenateOfUtils

This node, ImageConcatenateOfUtils, is an extension of the original ImageConcatenate node developed by @kijai.

Features

this code is original from https://github.com/ShmuelRonen/ComfyUI-Gemini_Flash_2.0_Exp, added new features. thanks to @ShmuelRonen.

GenderControlOutput

This node determines the output based on the input gender. If the gender input is ‘M’, it will output male-specific text, float, and integer values. If the gender input is ‘F’, it will output female-specific text, float, and integer values.

BooleanControlOutput

This node outputs different values based on a boolean input. If the boolean input is True, it will output the values of true_text, true_float, true_int, True, and False. If the boolean input is False, it will output the values of false_text, false_float, false_int, False, and True.

SplitMask

This node splits one mask into two masks of the same size according to the area of the submasks. If there are more than two areas, it will select the two largest submasks.

MaskFastGrow

This node is designed for growing masks quickly. When using the official or other mask growth nodes, the speed slows down significantly with large grow values, such as above 20. In contrast, this node maintains consistent speed regardless of the grow value.

MaskFromFaceModel

Generates a mask from the face model of the Reactor face swap node. The mask covers the facial area below the eyes, excluding the forehead. Enabling add_bbox_upper_points provides a rough approximation but lacks precision. If the forehead is essential for your application, consider using a different mask or adjusting the generated mask as needed.

MaskAutoSelector

Check the three input masks. If any are available, return the first. If none are available, raise an exception.

MaskCoverFourCorners

Generates a mask by covering the selected corners with circular edges. This mask can be used as an attention mask to remove watermarks from the corners.

MaskofCenter

Generates a mask by covering the center of the image with a circular edge. This mask can be used as an attention mask, then model can focus on the center of the image.

MaskAreaComparison

This node compares the area of the mask with the threshold. If the area is greater than the threshold, it will return True; otherwise, it will return False.

CheckpointLoaderSimpleWithSwitch

Enhanced the official LoadCheckpoint node by integrating three switches. Each switch controls whether a specific component is loaded. When a switch is turned off, the corresponding component will not be loaded. if you use the extra vae and close the model’s vae loading, that will save memory.

ImageResizeTo8x

Modified the image-resize-comfyui image resize node by adding logic to crop the resulting image size to 8 times size, similar to the VAE encode node. This avoids pixel differences when pasting back by the ImageCompositeMasked node.

ImageAutoSelector

This node is designed to automatically select the image from the input. If the prior image is not empty, return the prior image; otherwise, return the alternative image or the third image.

TextPreview

Added the node for convenience. The code is originally from ComfyUI-Custom-Scripts, thanks.

TextInputAutoSelector

Check the component and alternative input. If the component input is not empty, return this text; otherwise, return the alternative text.

MatchImageRatioToPreset

According to the input image ratio, decide which standard SDXL training size is the closest match. This is useful for subsequent image resizing and other processes.

AspectRatioSizeNodeOfUtils

Select aspect ratio (1:1, 9:16, 16:9, 3:4, etc.) and size preset (1k, 2k, 4k) to output corresponding width and height values. Supports “auto” mode to pass through input dimensions directly. Includes divisibility option (none/8/16) to ensure output values are aligned, and batch_size pass-through.

UpscaleImageWithModelIfNeed

Enhanced the official UpscaleImageWithModel node by adding a judge. If the input image area exceeds a predefined threshold, upscaling is bypassed. The threshold is a percentage of the SDXL standard size (1024×1024) area.

ImageCompositeWatermark

This node is designed to composite a watermark into the destination image. It can select the position of the watermark, resize the watermark according to the input ratio, and add a margin to the watermark.

ImageTransition

This node is designed to generate a transition image between two images. The first image gradually fades out while the second image simultaneously appears, creating a smooth transition effect.

ImageTransitionLeftToRight

This node is designed to generate a transition image between two images. The first image gradually slides to the right while the second image simultaneously appears from the left, creating a smooth transition effect.

ImageTransitionRightToLeft

This node is designed to generate a transition image between two images. The first image gradually slides to the left while the second image simultaneously appears from the right, creating a smooth transition effect.

ImageTransitionTopToBottom

This node is designed to generate a transition image between two images. The first image gradually slides down while the second image simultaneously appears from the top, creating a smooth vertical transition effect.

ImageTransitionBottomToTop

This node is designed to generate a transition image between two images. The first image gradually slides up while the second image simultaneously appears from the bottom, creating a smooth vertical transition effect.

ImageMaskColorAverage

This node is designed to calculate the average color of the image within the mask. It returns the decimal and hexadecimal values of the average color.

TorchCompileModelAdvancedOfUtils

This node enables model compilation using torch.compile. It extends ComfyUI’s original torch compile node by adding compile mode options and a toggle switch.

DetectorForNSFW

This node adapts the original model and inference code from nudenet for use with Comfy. A small 10MB default model, 320n.onnx, is provided. If you wish to use other models from that repository, download the ONNX model and place it in the models/nsfw directory, then set the appropriate detect_size.

From initial testing, the filtering effect is better than classifier models such as Falconsai/nsfw_image_detection.

You can also adjust the confidence levels for various rules such as buttocks_exposed to be more lenient or strict. Lower confidence levels will filter out more potential NSFW images. Setting the value to 1 will stop filtering for that specific feature.

output

The output_image includes the original image and the alternative image or the blank image. detect_result is the result of the detection with json format. filtered_image only includes the image after filtering, if it is just one image and nsfw, it raises an exception in the save_image node.

DeepfaceAnalyzeFaceAttributes

Notice: The face detection node depends on TensorFlow 2.17, which is now outdated and may cause compatibility issues. Therefore, it is no longer installed by default. If you need to use this node, please refer to requirements.txt to install the dependencies manually. Users who have previously installed this library are not affected.

This node integrates the deepface library to analyze face attributes (gender, race, emotion, age). It analyzes only the largest face in the image and supports processing one image at a time.

If the input image is a standard square face image, you can enable the standard_single_face_image switch. In this case, the node will skip face detection and analyze the attributes directly.

Upon the first run, the node will download the deepface models, which may take some time.

Note: If you encounter the following exception while running the node:

“`

ValueError: The layer sequential has never been called and thus has no defined input.

“`

Please set the environment variable TF_USE_LEGACY_KERAS to 1, then restart ComfyUI.

Caution: If you are not using this node, please remove the dependencies in requirements.txt. Otherwise, it will install TensorFlow version 2.17.x.
