ComfyUI Node: Image Overlay

Image Overlay:

The Image Overlay node is designed to enhance your image processing workflow by allowing you to overlay labels onto images. This node is particularly useful for adding annotations, captions, or any form of textual information directly onto images, which can be beneficial for creating informative visuals or datasets with embedded metadata. The node supports various types of labels, including floating-point numbers, integers, and strings, providing flexibility in the kind of information you can overlay. By integrating this node into your workflow, you can streamline the process of labeling images, making it easier to organize and interpret visual data.

Image Overlay Input Parameters:

images

This parameter accepts a list of images in the form of tensors. These images are the base onto which the labels will be overlaid. The images should be pre-processed and converted into a suitable format for tensor operations, typically as floating-point arrays normalized between 0 and 1.

float_labels

This optional parameter allows you to provide a list of floating-point numbers to be used as labels on the images. These labels can represent continuous data or measurements that you wish to display on the images. If not provided, no floating-point labels will be added.

int_labels

This optional parameter is for providing a list of integer labels. These can be used to denote categorical data or identifiers that are relevant to the images. If omitted, no integer labels will be overlaid.

str_labels

This optional parameter accepts a list of strings to be used as labels. These strings can be any textual information you want to display on the images, such as names, descriptions, or annotations. If not specified, no string labels will be added.

Image Overlay Output Parameters:

output_images

This output consists of a list of images with the specified labels overlaid. Each image in the list corresponds to an input image with the appropriate labels applied, allowing you to visually verify and utilize the labeled images in further processing or analysis.

Image Overlay Usage Tips:

• Ensure that the input images are pre-processed and converted to tensors with appropriate normalization to achieve the best results when overlaying labels.
• Use the string labels parameter to add descriptive annotations to your images, which can be particularly useful for creating educational or presentation materials.

Image Overlay Common Errors and Solutions:

Mismatched label and image count

• Explanation: The number of labels provided does not match the number of images.
• Solution: Ensure that the length of each label list matches the number of images you are processing.

Invalid image format

• Explanation: The input images are not in a supported format or are not properly converted to tensors.
• Solution: Verify that your images are correctly formatted as tensors and normalized between 0 and 1 before inputting them into the node.
