ComfyUI Node: BMAB Resize By Person

BMAB Resize By Person:

BMAB Resize By Person is a specialized node designed to resize images based on the presence and size of a person detected within the image. This node leverages advanced object detection techniques to identify the largest person in the image and adjusts the image dimensions accordingly. The primary goal of this node is to ensure that the person remains the focal point of the image, maintaining a specific aspect ratio and alignment. This is particularly useful for applications where the subject's prominence and positioning are crucial, such as in portrait photography, social media content, and other visual arts. By automating the resizing process, BMAB Resize By Person helps you save time and achieve consistent results, enhancing the overall quality and impact of your images.

BMAB Resize By Person Input Parameters:

bind

This parameter is of type BMAB bind and is required. It serves as a binding context for the node, ensuring that the necessary configurations and settings are applied during the image processing.

steps

This integer parameter defines the number of steps for the resizing process. It has a default value of 20, with a minimum of 0 and a maximum of 10000. Adjusting this value can impact the precision and quality of the resizing operation.

cfg_scale

This float parameter, with a default value of 8.0, controls the configuration scale. It ranges from 0.0 to 100.0, with increments of 0.1. This parameter influences the overall scaling factor applied during the resizing process.

sampler_name

This parameter allows you to select the sampler to be used. It includes options like Use same sampler and other samplers available in comfy.samplers.KSampler.SAMPLERS. The choice of sampler can affect the quality and style of the resized image.

scheduler

Similar to sampler_name, this parameter lets you choose the scheduler for the process. Options include Use same scheduler and those listed in comfy.samplers.KSampler.SCHEDULERS. The scheduler determines the sequence and timing of the resizing steps.

denoise

This float parameter, ranging from 0.0 to 1.0 with a default value of 0.5, controls the level of denoising applied to the image. Adjusting this value can help reduce noise and improve the clarity of the resized image.

method

This parameter specifies the resizing method to be used. Available options are stretching, inpaint, and inpaint+lama. Each method offers a different approach to resizing, affecting the final appearance of the image.

alignment

This parameter determines the alignment of the resized image. Options include bottom, top, top-right, right, bottom-right, bottom-left, left, top-left, and center. The alignment setting ensures that the person remains properly positioned within the resized image.

ratio

This float parameter, with a default value of 0.85, defines the aspect ratio for resizing. It ranges from 0.1 to 0.95, with increments of 0.01. The ratio helps maintain the proportionality of the person within the image.

dilation

This integer parameter, with a default value of 30, controls the dilation applied to the image. It ranges from 4 to 128, with increments of 1. Dilation can affect the boundaries and edges of the resized image, enhancing the prominence of the person.

image (optional)

This optional parameter allows you to provide an image for processing. If not provided, the node will use the default image from the binding context.

BMAB Resize By Person Output Parameters:

BMAB bind

This output parameter returns the updated BMAB bind context, reflecting the changes and settings applied during the resizing process. It ensures that subsequent nodes can utilize the updated context for further processing.

image

This output parameter returns the resized image. The image is adjusted based on the presence and size of the person, maintaining the specified aspect ratio and alignment. The output image is ready for further use or display.

BMAB Resize By Person Usage Tips:

• Ensure that the input image contains a clearly visible person to achieve the best results.
• Experiment with different method and alignment settings to find the optimal configuration for your specific use case.
• Adjust the ratio parameter to maintain the desired aspect ratio, especially when working with images of varying dimensions.
• Use the denoise parameter to reduce noise and enhance the clarity of the resized image, particularly in low-light conditions.

BMAB Resize By Person Common Errors and Solutions:

No person detected in the image

• Explanation: The node could not detect any person in the provided image.
• Solution: Ensure that the input image contains a clearly visible person and try adjusting the detection threshold if available.

Invalid ratio value

• Explanation: The ratio parameter is set to a value outside the acceptable range.
• Solution: Set the ratio parameter to a value between 0.1 and 0.95.

Image processing failed

• Explanation: An error occurred during the image resizing process.
• Solution: Check the input parameters for any invalid values and ensure that the input image is in a supported format. If the issue persists, try using a different resizing method or alignment setting.
