ComfyUI Node: 🔧 Image Enhance Difference

🔧 Image Enhance Difference+:

The ImageEnhanceDifference+ node is designed to analyze and enhance the differences between two images. This node is particularly useful for highlighting subtle variations or changes between two images, which can be beneficial in various image analysis tasks. By applying a mathematical operation to the pixel values of the two input images, the node generates a new image that emphasizes the differences. This can be useful for tasks such as change detection, quality inspection, or artistic effects where understanding the differences between two images is crucial. The node allows you to control the intensity of the enhancement through an exponent parameter, providing flexibility in how pronounced the differences appear in the output image.

🔧 Image Enhance Difference+ Input Parameters:

image1

This parameter represents the first input image that you want to compare. It serves as the reference image against which the differences will be calculated. The image should be in a compatible format and resolution for accurate comparison.

image2

This parameter represents the second input image that you want to compare with the first image. If the resolution of this image does not match the first image, it will be automatically resized to match the dimensions of the first image using a bicubic upscale method. This ensures that the comparison is accurate and meaningful.

exponent

The exponent parameter controls the intensity of the enhancement applied to the differences between the two images. It is a floating-point value that ranges from 0.00 to 1.00, with a default value of 0.75. A lower exponent value will result in a more subtle enhancement, while a higher value will make the differences more pronounced. This parameter allows you to fine-tune the output based on your specific needs.

🔧 Image Enhance Difference+ Output Parameters:

IMAGE

The output of this node is a single image that highlights the differences between the two input images. The differences are enhanced based on the specified exponent value, and the resulting image is clamped to ensure that pixel values remain within a valid range. This output image can be used for further analysis, visualization, or as an input to other image processing nodes.

🔧 Image Enhance Difference+ Usage Tips:

• To achieve a more subtle difference enhancement, use a lower exponent value closer to 0.00.
• For more pronounced differences, increase the exponent value towards 1.00.
• Ensure that the input images are pre-processed to have similar lighting and color conditions for more accurate difference detection.
• Use this node in combination with other image processing nodes to create complex image analysis workflows.

🔧 Image Enhance Difference+ Common Errors and Solutions:

"Input images must have the same dimensions"

• Explanation: This error occurs when the two input images have different resolutions and the automatic resizing fails.
• Solution: Ensure that both input images have the same resolution before feeding them into the node, or check the resizing settings.

"Invalid exponent value"

• Explanation: This error occurs when the exponent value is set outside the allowed range of 0.00 to 1.00.
• Solution: Adjust the exponent value to be within the valid range (0.00 to 1.00).

"Unsupported image format"

• Explanation: This error occurs when the input images are in an unsupported format.
• Solution: Convert the input images to a supported format such as PNG or JPEG before using the node.
