🐰 Upscaler - McBoaty [1/3] v5 /u Input Parameters:

image

This parameter represents the input image that you want to upscale. It must be provided as a tensor, which is a multi-dimensional array used in deep learning models. The image should be pre-processed and ready for upscaling. If the image is not provided or is not in the correct format, the node will raise an error. There are no specific minimum or maximum values for this parameter, but it must be a valid tensor.

upscale_model

This parameter specifies the model to be used for the upscaling process. Different models may offer various levels of detail and quality, so selecting the appropriate model can significantly impact the final output. The available options for this parameter will depend on the models installed in your environment.

max_iterations

This parameter determines the number of iterations the upscaling process will go through. More iterations can lead to higher quality results but will also increase the processing time. The default value is typically set to a reasonable number that balances quality and performance.

add_noise

This boolean parameter indicates whether to add noise during the upscaling process. Adding noise can sometimes help in achieving a more natural look, especially in images with a lot of fine details. The default value is usually set to False.

noise_seed

If add_noise is enabled, this parameter specifies the seed for the noise generation. Using a fixed seed ensures that the noise added is consistent across different runs, which can be useful for reproducibility. The default value is typically set to a random seed.

cfg

This parameter stands for configuration settings that control various aspects of the upscaling process. It includes settings like the strength of the upscaling effect, the balance between speed and quality, and other fine-tuning options. The default values are usually optimized for general use cases.

positive

This parameter is used to provide positive prompts or guidance to the upscaling model. It helps the model understand what features to enhance or focus on during the upscaling process. The default value is usually an empty string or a generic prompt.

negative

This parameter is used to provide negative prompts or guidance to the upscaling model. It helps the model understand what features to avoid or minimize during the upscaling process. The default value is usually an empty string or a generic prompt.

sampler

This parameter specifies the sampling method to be used during the upscaling process. Different sampling methods can produce different results, so choosing the right one can impact the final output. The available options will depend on the methods supported by the upscaling model.

sigmas

This parameter controls the sigma values used in the upscaling process. Sigma values affect the level of detail and smoothness in the final output. The default values are usually set to provide a good balance between detail and smoothness.

feather_mask

This boolean parameter indicates whether to apply a feather mask during the upscaling process. A feather mask can help in blending the upscaled image with the original, resulting in a smoother transition. The default value is usually set to False.

🐰 Upscaler - McBoaty [1/3] v5 /u Output Parameters:

image

This parameter represents the upscaled image output by the node. It is a tensor that contains the enhanced version of the input image, with improved resolution and quality.

grid_prompts

This parameter contains the prompts used during the upscaling process. It provides insight into the guidance given to the model, which can be useful for understanding how the final output was achieved.

output_tiles

This parameter represents the individual tiles or segments of the upscaled image. These tiles are combined to form the final upscaled image, and this parameter can be useful for further processing or analysis.

output_info

This parameter provides detailed information about the upscaling process, including the original and final dimensions of the image, the time taken for the process, and other relevant metrics. It helps in understanding the performance and effectiveness of the upscaling.

🐰 Upscaler - McBoaty [1/3] v5 /u Usage Tips:

• Ensure that the input image is a valid tensor to avoid errors during the upscaling process.
• Experiment with different upscale models to find the one that best suits your needs and provides the desired level of detail.
• Adjust the max_iterations parameter to balance between processing time and output quality.
• Use positive and negative prompts to guide the upscaling model and achieve specific enhancements or avoid certain features.
• If you want a more natural look, consider enabling the add_noise parameter and setting an appropriate noise_seed.
