ComfyUI Node: ImageFilterBilateralBlur

ImageFilterBilateralBlur:

The ImageFilterBilateralBlur node is designed to apply a bilateral blur effect to your images, which is particularly useful for reducing noise while preserving edges. This type of blur is ideal for scenarios where you want to smooth out textures and noise without losing important details and edges in the image. The bilateral filter works by considering both the spatial distance and the intensity difference between pixels, making it a powerful tool for enhancing the visual quality of your images in a balanced manner.

ImageFilterBilateralBlur Input Parameters:

images

This parameter accepts the image or images you want to process. The input should be in the format of an image tensor.

size

The size parameter determines the diameter of each pixel neighborhood used during filtering. A larger size will result in a stronger blur effect. The default value is 10, with a minimum value of 1, and it increments in steps of 2.

sigma_color

The sigma_color parameter controls the filter's sensitivity to color differences. A higher value means that pixels with different colors will be mixed together more, resulting in a stronger blur. The default value is 1.0, with a maximum value of 1.0, and it increments in steps of 0.01.

sigma_intensity

The sigma_intensity parameter controls the filter's sensitivity to intensity differences. A higher value means that pixels with different intensities will be mixed together more, resulting in a stronger blur. The default value is 1.0, with a maximum value of 1.0, and it increments in steps of 0.01.

ImageFilterBilateralBlur Output Parameters:

IMAGE

The output is the processed image with the bilateral blur effect applied. This output retains the important edges and details while reducing noise and smoothing out textures, making it ideal for enhancing the visual quality of your images.

ImageFilterBilateralBlur Usage Tips:

• For a subtle blur effect that preserves most details, use smaller values for size, sigma_color, and sigma_intensity.
• To achieve a stronger blur effect, increase the size parameter while adjusting sigma_color and sigma_intensity to balance the color and intensity sensitivity.
• Experiment with different combinations of size, sigma_color, and sigma_intensity to find the optimal settings for your specific image and desired outcome.

ImageFilterBilateralBlur Common Errors and Solutions:

ValueError: Unsupported blur type.

• Explanation: This error occurs if an unsupported blur type is specified.
• Solution: Ensure that you are using the correct blur type parameters as defined in the node's input parameters.

TypeError: Input image is not in the correct format.

• Explanation: This error occurs if the input image is not in the expected tensor format.
• Solution: Verify that the input image is correctly formatted as an image tensor before passing it to the node.

ValueError: Size parameter must be an odd number.

• Explanation: The size parameter must be an odd number for the bilateral filter to function correctly.
• Solution: Ensure that the size parameter is set to an odd number by adjusting the value accordingly.
