ComfyUI Node: Image Analyze

Image Analyze:

The Image Analyze node is designed to help you extract and analyze specific characteristics of an image, providing insights into its color levels and distribution. This node can operate in two distinct modes: "Black White Levels" and "RGB Levels". By analyzing the image in these modes, you can gain a deeper understanding of the image's tonal range or the frequency of different color channels. This can be particularly useful for tasks such as image enhancement, correction, or artistic manipulation, where understanding the underlying color information is crucial.

Image Analyze Input Parameters:

image

This parameter expects an image input that you want to analyze. The image should be in a format compatible with the node, typically a tensor representation of an image. The image serves as the primary data source for the analysis process.

mode

This parameter determines the type of analysis to be performed on the image. It accepts two options: "Black White Levels" and "RGB Levels". "Black White Levels" mode analyzes the image's black and white levels, providing insights into its tonal range. "RGB Levels" mode analyzes the frequency of the red, green, and blue channels, offering a detailed view of the color distribution within the image. The default value is "Black White Levels".

Image Analyze Output Parameters:

IMAGE

The output of this node is the analyzed image, returned in the same tensor format as the input. Depending on the selected mode, the output image will reflect the results of the black and white levels analysis or the RGB levels analysis. This output can be used for further processing or visualization.

Image Analyze Usage Tips:

• Use the "Black White Levels" mode to understand the tonal range of your image, which can help in tasks like contrast adjustment or black-and-white conversion.
• Use the "RGB Levels" mode to analyze the color distribution in your image, which can be useful for color correction or artistic effects.
• Combine this node with other image processing nodes to create a comprehensive image analysis and enhancement pipeline.

Image Analyze Common Errors and Solutions:

Invalid image input

• Explanation: The input image is not in the expected tensor format.
• Solution: Ensure that the image is correctly converted to a tensor before passing it to the node.

Unsupported mode selected

• Explanation: The mode parameter is set to a value that is not recognized by the node.
• Solution: Verify that the mode parameter is set to either "Black White Levels" or "RGB Levels".
