ComfyUI Node: 💪TB | Tiny Upscaler (advanced)

💪TB | Tiny Upscaler (advanced):

The TinyUpscalerAdvanced __TinyBreaker node is designed to enhance the quality of images by upscaling them using a custom sampler and sigma values. This advanced upscaling technique is part of the ComfyUI-TinyBreaker suite, which leverages the hybrid capabilities of the TinyBreaker model, combining the strengths of PixArt and Stable Diffusion (SD). The primary goal of this node is to improve image resolution while maintaining or enhancing the quality, making it an essential tool for AI artists looking to refine their digital artwork. By utilizing this node, you can achieve higher quality results in your image processing tasks, benefiting from the sophisticated algorithms and parameters that govern the upscaling process.

💪TB | Tiny Upscaler (advanced) Input Parameters:

Custom Sampler

The custom sampler parameter allows you to select the specific sampling method used during the upscaling process. This choice can significantly impact the final image quality, as different samplers may handle image details and noise differently. While the exact options for this parameter are not specified, it is crucial to experiment with different samplers to find the one that best suits your image's needs. The default sampler is typically set to a balanced option that works well for most images.

Sigma Values

Sigma values are used to control the level of detail and noise reduction during the upscaling process. Higher sigma values generally result in smoother images with less noise, while lower values preserve more detail but may retain some noise. The range of sigma values is not explicitly provided, but it is essential to adjust these values based on the specific requirements of your image to achieve the desired balance between detail and smoothness.

💪TB | Tiny Upscaler (advanced) Output Parameters:

Upscaled Image

The primary output of the TinyUpscalerAdvanced __TinyBreaker node is the upscaled image. This image is a higher resolution version of the input image, with improved quality achieved through the advanced upscaling techniques employed by the node. The upscaled image should exhibit enhanced details and reduced noise, making it suitable for high-quality digital art and print applications.

💪TB | Tiny Upscaler (advanced) Usage Tips:

• Experiment with different custom samplers to find the one that best enhances the specific features of your image.
• Adjust sigma values carefully to balance detail preservation and noise reduction, depending on the characteristics of your input image.
• Use the upscaled image output for high-resolution prints or digital displays to fully appreciate the enhanced quality.

💪TB | Tiny Upscaler (advanced) Common Errors and Solutions:

"Invalid Sampler Selection"

• Explanation: This error occurs when an unsupported or incorrect sampler is selected.
• Solution: Ensure that you select a valid sampler from the available options. Refer to the documentation or user interface for the list of supported samplers.

"Sigma Value Out of Range"

• Explanation: This error indicates that the sigma value provided is outside the acceptable range.
• Solution: Adjust the sigma value to fall within the recommended range. If the range is not specified, start with moderate values and adjust incrementally to achieve the desired effect.
