ComfyUI Node: 📱 CR Simple Image Compare

📱 CR Simple Image Compare:

The CR Simple Image Compare node is designed to facilitate the comparison of two images by evaluating their visual differences. This node is particularly useful for AI artists who need to assess changes between image versions, such as before and after applying filters or transformations. By providing a straightforward method to compare images, it helps in identifying subtle differences that might not be immediately noticeable. This node can be an essential tool in quality control, ensuring that the desired modifications have been accurately applied without unintended alterations.

📱 CR Simple Image Compare Input Parameters:

Image 1

This parameter represents the first image to be compared. It serves as the baseline image against which the second image will be evaluated. The quality and resolution of this image can significantly impact the comparison results, so it is important to use a high-quality image for accurate assessment.

Image 2

This parameter represents the second image to be compared. It is the image that will be evaluated against the first image to identify any differences. Similar to the first image, the quality and resolution of this image are crucial for obtaining precise comparison results.

📱 CR Simple Image Compare Output Parameters:

Difference Image

This output parameter provides an image that highlights the differences between the two input images. Areas where the images differ will be marked, making it easy to identify changes or discrepancies. This output is particularly useful for visualizing the impact of applied modifications or transformations.

Similarity Score

This output parameter provides a numerical score representing the similarity between the two input images. The score ranges from 0 to 1, where 1 indicates identical images and 0 indicates completely different images. This score helps quantify the degree of similarity, providing a clear metric for comparison.

📱 CR Simple Image Compare Usage Tips:

• Ensure both input images are of the same resolution and quality to achieve accurate comparison results.
• Use high-quality images to avoid false positives in the difference image output.
• Utilize the similarity score to quickly assess the degree of changes between images, especially when dealing with large batches of images.

📱 CR Simple Image Compare Common Errors and Solutions:

Image resolution mismatch

• Explanation: This error occurs when the input images have different resolutions.
• Solution: Ensure that both input images have the same resolution before performing the comparison.

Unsupported image format

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

Image file not found

• Explanation: This error occurs when the specified image file cannot be located.
• Solution: Verify the file paths and ensure that the image files exist and are accessible.

Insufficient memory

• Explanation: This error occurs when the system does not have enough memory to process the images.
• Solution: Close other applications to free up memory or use images with lower resolutions.
