ComfyUI Node: ImageFilterMax

ImageFilterMax:

The ImageFilterMax node is designed to enhance the details in your images by applying a maximum filter. This filter works by replacing each pixel in the image with the maximum value of the pixels in a surrounding region defined by the filter size. The primary benefit of using this node is to emphasize the brightest areas and enhance the contrast in your images, making it particularly useful for highlighting features and creating striking visual effects. This node is part of the image filtering category and is ideal for AI artists looking to add a unique touch to their digital artwork.

ImageFilterMax Input Parameters:

images

This parameter accepts the input image(s) that you want to apply the maximum filter to. The images should be in a compatible format that the node can process.

size

The size parameter determines the size of the region around each pixel that the filter will consider when calculating the maximum value. The default value is 2, with a minimum value of 0 and increments in steps of 2. Increasing the size will result in a more pronounced effect, as a larger region will be considered for each pixel, enhancing the contrast and details more significantly.

ImageFilterMax Output Parameters:

IMAGE

The output is the filtered image where each pixel has been replaced by the maximum value of the surrounding region defined by the size parameter. This results in an image with enhanced contrast and highlighted features, making it visually striking and detailed.

ImageFilterMax Usage Tips:

• To achieve a subtle enhancement, use a smaller size value. This will make the changes less pronounced and maintain more of the original image's details.
• For a more dramatic effect, increase the size value. This will enhance the contrast and make the bright areas more prominent, which can be useful for creating high-impact visual effects.

ImageFilterMax Common Errors and Solutions:

Invalid image format

• Explanation: The input image is not in a format that the node can process.
• Solution: Ensure that the input image is in a compatible format, such as JPEG or PNG.

Size parameter out of range

• Explanation: The size parameter is set to a value that is not within the acceptable range.
• Solution: Adjust the size parameter to be within the specified range (minimum 0, increments of 2).

Image processing failed

• Explanation: An error occurred during the image processing.
• Solution: Check the input image and parameters for any inconsistencies or errors, and try again. If the problem persists, consider using a different image or adjusting the parameters.
