ComfyUI Node: ImageFilterGaussianBlurAdvanced

ImageFilterGaussianBlurAdvanced:

The ImageFilterGaussianBlurAdvanced node is designed to apply an advanced Gaussian blur effect to images, providing a smooth and aesthetically pleasing blur that can enhance the visual quality of your artwork. This node allows you to fine-tune the blur effect by adjusting the size and intensity of the blur in both the horizontal and vertical directions. By leveraging the Gaussian blur technique, it ensures that the transition between blurred and non-blurred areas is gradual and natural, making it ideal for softening edges, reducing noise, and creating depth in your images. This node is particularly useful for AI artists looking to add a professional touch to their creations by controlling the blur parameters with precision.

ImageFilterGaussianBlurAdvanced Input Parameters:

images

This parameter accepts the image or images you want to apply the Gaussian blur to. The input should be in the form of an image tensor.

size_x

This parameter controls the horizontal size of the Gaussian blur kernel. The size determines the extent of the blur effect in the horizontal direction. The default value is 10, with a minimum value of 2, and it increments in steps of 2. Adjusting this value will affect how much the image is blurred horizontally.

size_y

This parameter controls the vertical size of the Gaussian blur kernel. The size determines the extent of the blur effect in the vertical direction. The default value is 10, with a minimum value of 2, and it increments in steps of 2. Adjusting this value will affect how much the image is blurred vertically.

sigma_x

This parameter specifies the standard deviation of the Gaussian function in the horizontal direction. A higher value results in a more pronounced blur effect. The default value is 0, which means the standard deviation is calculated based on the kernel size.

sigma_y

This parameter specifies the standard deviation of the Gaussian function in the vertical direction. A higher value results in a more pronounced blur effect. The default value is 0, which means the standard deviation is calculated based on the kernel size.

ImageFilterGaussianBlurAdvanced Output Parameters:

IMAGE

The output is the image or images with the applied Gaussian blur effect. The resulting image will have a smooth and natural blur, with the extent and intensity of the blur determined by the input parameters.

ImageFilterGaussianBlurAdvanced Usage Tips:

• To achieve a subtle blur effect, start with smaller values for size_x and size_y and gradually increase them until you reach the desired level of blur.
• Use higher values for sigma_x and sigma_y if you want a more pronounced and intense blur effect, especially for creating depth or focusing attention on specific areas of the image.
• Experiment with different combinations of size_x, size_y, sigma_x, and sigma_y to find the perfect balance for your artwork.

ImageFilterGaussianBlurAdvanced Common Errors and Solutions:

Image size mismatch error

• Explanation: This error occurs when the input image dimensions do not match the expected dimensions for the Gaussian blur operation.
• Solution: Ensure that the input image dimensions are consistent and compatible with the Gaussian blur kernel size. Resize or crop the image if necessary.

Invalid kernel size error

• Explanation: This error occurs when the specified size_x or size_y values are not valid (e.g., less than the minimum value).
• Solution: Check the size_x and size_y values to ensure they meet the minimum requirement of 2 and are in increments of 2. Adjust the values accordingly.

Sigma value error

• Explanation: This error occurs when the sigma_x or sigma_y values are set to negative numbers or non-numeric values.
• Solution: Ensure that sigma_x and sigma_y are set to non-negative numeric values. If you want the standard deviation to be calculated automatically, set these parameters to 0.
