ComfyUI Node: Image Gaussian Blur

Image Gaussian Blur:

The ImageGaussianBlur node is designed to apply a Gaussian blur effect to images, which is a common technique used in image processing to reduce noise and detail. This node is particularly useful for creating a smooth, soft appearance in images, which can enhance the aesthetic quality or prepare the image for further processing steps. By blurring the image, you can achieve a more polished look or focus attention on specific areas by reducing the prominence of less important details. The Gaussian blur method is known for its ability to produce a natural-looking blur effect, making it a valuable tool for AI artists looking to refine their digital artwork.

Image Gaussian Blur Input Parameters:

images

This parameter accepts a list of images that you want to apply the Gaussian blur effect to. Each image should be in a compatible format that the node can process. The images parameter is essential as it provides the raw data that will be transformed by the blur effect.

radius

The radius parameter determines the strength of the blur effect. It specifies the radius of the Gaussian kernel used to blur the image. A larger radius results in a stronger blur, while a smaller radius produces a more subtle effect. The radius can range from a minimum value of 1 to a maximum value of 100, with a default value of 1. Adjusting this parameter allows you to control the extent of the blurring to achieve the desired visual outcome.

Image Gaussian Blur Output Parameters:

IMAGE

The output of the ImageGaussianBlur node is a blurred version of the input images. This output retains the same dimensions and format as the original images but with the applied Gaussian blur effect. The blurred images can be used directly in your artwork or as a pre-processed input for further image manipulation tasks.

Image Gaussian Blur Usage Tips:

• Experiment with different radius values to find the optimal blur strength for your specific image. A smaller radius is ideal for slight smoothing, while a larger radius can create a dreamy, out-of-focus effect.
• Use the ImageGaussianBlur node to reduce noise in images before applying other image processing techniques, such as edge detection or sharpening, to improve the overall quality of the results.

Image Gaussian Blur Common Errors and Solutions:

ValueError: Invalid image format

• Explanation: This error occurs when the input images are not in a compatible format that the node can process.
• Solution: Ensure that the images are in a supported format, such as JPEG or PNG, and try again.

ValueError: Radius out of range

• Explanation: This error occurs when the radius parameter is set to a value outside the allowed range of 1 to 100.
• Solution: Adjust the radius parameter to a value within the specified range and try again.

RuntimeError: CUDA out of memory

• Explanation: This error occurs when the GPU does not have enough memory to process the images with the specified blur radius.
• Solution: Reduce the radius value or process smaller batches of images to decrease the memory usage. Alternatively, consider using a machine with more GPU memory.
