ComfyUI Node: ImageFilterMedianBlur

ImageFilterMedianBlur:

The ImageFilterMedianBlur node is designed to apply a median blur effect to your images, which is particularly useful for reducing noise and smoothing out textures while preserving edges. This node leverages the median blur technique, which replaces each pixel's value with the median value of the neighboring pixels. This method is highly effective in removing salt-and-pepper noise and is widely used in image preprocessing tasks to enhance the quality of the image before further processing or analysis. By using this node, you can achieve a cleaner and more visually appealing image, making it an essential tool for AI artists looking to refine their digital artwork.

ImageFilterMedianBlur Input Parameters:

images

This parameter expects the input image(s) that you want to apply the median blur effect to. The images should be in a format compatible with the node's processing capabilities.

size

The size parameter determines the size of the kernel used for the median blur. It specifies the width and height of the square neighborhood of pixels used to calculate the median value. The size must be an odd integer, and the node will automatically adjust the value to ensure it meets this requirement. The default value is 10, with a minimum value of 1, and it increments in steps of 2. Adjusting this parameter will impact the degree of blurring, with larger values resulting in a stronger blur effect.

ImageFilterMedianBlur Output Parameters:

IMAGE

The output of this node is the processed image(s) with the median blur effect applied. The resulting image will have reduced noise and smoother textures, while edges and important details are preserved. This output can be used directly in your artwork or as a preprocessed input for further image manipulation tasks.

ImageFilterMedianBlur Usage Tips:

• For images with significant noise, increase the size parameter to achieve a more pronounced noise reduction effect.
• Use a smaller size value if you want to preserve more details and only slightly smooth the image.
• Experiment with different size values to find the optimal balance between noise reduction and detail preservation for your specific image.

ImageFilterMedianBlur Common Errors and Solutions:

Invalid size value

• Explanation: The size parameter must be an odd integer. If an even number is provided, the node will adjust it by subtracting 1. - Solution: Ensure that the size parameter is set to an odd integer. If you encounter issues, try manually setting the value to an odd number.

Image format not supported

• Explanation: The input image(s) must be in a format compatible with the node's processing capabilities.
• Solution: Verify that your input images are in a supported format. Convert the images to a compatible format if necessary before using the node.
