LayerMask: Transparent Background Ultra(Advance) Input Parameters:

image

This parameter represents the input image(s) that you want to process to create a transparent background. The node will apply its algorithms to these images to isolate the subject from the background.

model

The model parameter allows you to select from a list of available models that the node can use to process the image. The choice of model can affect the quality and style of the transparency effect, so selecting the appropriate model is crucial for achieving the desired results.

detail_method

This parameter specifies the method used to refine the details of the transparency effect. Options include VITMatte, VITMatte(local), PyMatting, and GuidedFilter. Each method offers different strengths in handling edges and fine details, allowing you to choose the best approach for your specific image.

detail_erode

detail_erode is an integer parameter that controls the amount of erosion applied to the mask's details. It ranges from 1 to 255, with a default value of 6. Erosion can help refine the edges of the mask by reducing small artifacts, but excessive erosion may remove important details.

detail_dilate

Similar to detail_erode, detail_dilate is an integer parameter that controls the dilation applied to the mask's details. It also ranges from 1 to 255, with a default value of 6. Dilation can help fill in gaps in the mask, enhancing the coverage of the subject.

black_point

This float parameter, ranging from 0.01 to 0.98 with a default of 0.01, adjusts the black point of the mask. It helps in setting the threshold for the darkest areas of the mask, influencing how much of the background is considered transparent.

white_point

The white_point parameter, ranging from 0.02 to 0.99 with a default of 0.99, adjusts the white point of the mask. It sets the threshold for the lightest areas, affecting the transparency of the subject itself.

process_detail

A boolean parameter that determines whether additional detail processing is applied. When set to true, the node will perform extra steps to enhance the mask's detail, which can improve the quality of the transparency effect.

device

This parameter allows you to select the processing device, either cuda or cpu. Choosing cuda can significantly speed up processing if you have a compatible GPU, while cpu is suitable for systems without GPU support.

max_megapixels

A float parameter that sets the maximum number of megapixels for processing, ranging from 1 to 999 with a default of 2.0. This helps manage memory usage and processing time, especially for high-resolution images.

LayerMask: Transparent Background Ultra(Advance) Output Parameters:

image

The image output is the processed image with a transparent background. This output allows you to see the results of the node's processing, with the subject isolated from the background.

mask

The mask output provides the transparency mask used to create the transparent background. This mask can be used for further processing or adjustments, offering flexibility in how you use the node's results.

LayerMask: Transparent Background Ultra(Advance) Usage Tips:

• Experiment with different detail_method options to find the best fit for your image's complexity and desired level of detail.
• Adjust detail_erode and detail_dilate to fine-tune the mask's edges, balancing between removing artifacts and preserving important details.
• Use black_point and white_point sliders to control the transparency levels, ensuring that the subject remains visible while the background is effectively removed.
• If you have a compatible GPU, set the device to cuda for faster processing times, especially with high-resolution images.

LayerMask: Transparent Background Ultra(Advance) Common Errors and Solutions:

Model not found

• Explanation: This error occurs when the specified model is not available in the system.
• Solution: Ensure that the model name is correctly specified and that the model is installed and accessible by the node.

CUDA device not available

• Explanation: This error indicates that the node is set to use CUDA, but no compatible GPU is detected.
• Solution: Check your system's GPU compatibility and drivers. If a GPU is not available, switch the device parameter to cpu.

Image size exceeds maximum megapixels

• Explanation: The input image exceeds the maximum megapixels limit set by the max_megapixels parameter.
• Solution: Increase the max_megapixels value or reduce the resolution of the input image to fit within the limit.
