ComfyUI Node: Extract pose part v4.7.3

Extract pose part v4.7.3:

The tri3d-extract_pose_part node is designed to facilitate the extraction of specific body parts from an image based on pose estimation data. This node is particularly useful for AI artists and developers who need to isolate and manipulate certain regions of an image, such as the torso, arms, or legs, for further processing or artistic effects. By leveraging pose estimation data, the node can accurately identify and extract regions around body parts, allowing for precise control over the image manipulation process. This capability is beneficial for applications in animation, virtual reality, and augmented reality, where understanding and manipulating human poses is crucial. The node's functionality is enhanced by its ability to define extraction regions as a percentage of the image size, providing flexibility in how much of the surrounding area is included in the extraction.

Extract pose part v4.7.3 Input Parameters:

image

The image parameter is the input image from which body parts will be extracted. It serves as the primary source for the node's operations, and its quality and resolution can impact the accuracy of the extraction process. This parameter is required and must be provided in a compatible image format.

pose_json

The pose_json parameter is a string that specifies the path to a JSON file containing pose estimation data. This data is crucial for identifying the locations of body parts within the image. The default value is "dwpose/keypoints/input.json", and it should be formatted correctly to ensure accurate extraction.

width_pad

The width_pad parameter is a float that determines the horizontal padding around the extracted body part, expressed as a percentage of the image width. This allows for additional context to be included in the extraction. The default value is 1.0, with a minimum of 0.0 and a maximum of 100.0, adjustable in increments of 0.01.

height_pad

The height_pad parameter is a float that specifies the vertical padding around the extracted body part, expressed as a percentage of the image height. Similar to width_pad, it provides flexibility in the amount of surrounding area included. The default value is 1.0, with a range from 0.0 to 100.0, adjustable in increments of 0.01.

shoulders

The shoulders parameter is a boolean that indicates whether the shoulder region should be included in the extraction. By default, this is set to False. Enabling this option can be useful when the shoulder area is of particular interest for the task at hand.

Extract pose part v4.7.3 Output Parameters:

image

The image output parameter provides the resulting image after the specified body parts have been extracted. This image will contain only the regions of interest, as defined by the input parameters, allowing for further processing or analysis.

coords

The coords output parameter is a string that contains the coordinates of the extracted region in the format "xmin, xmax, ymin, ymax". These coordinates can be used to understand the location of the extracted parts within the original image or to reposition them later.

Extract pose part v4.7.3 Usage Tips:

• Ensure that the pose_json file is correctly formatted and contains accurate pose data to improve the precision of the extraction process.
• Adjust the width_pad and height_pad parameters to include more or less of the surrounding area, depending on the specific requirements of your project.
• Use the shoulders parameter to include the shoulder region if it is relevant to your task, such as in fashion design or virtual try-on applications.

Extract pose part v4.7.3 Common Errors and Solutions:

Invalid pose_json path

• Explanation: The specified path to the pose JSON file is incorrect or the file is missing.
• Solution: Verify that the pose_json path is correct and that the file exists at the specified location. Ensure the file is accessible and properly formatted.

Image format not supported

• Explanation: The input image is in a format that is not supported by the node.
• Solution: Convert the image to a supported format, such as JPEG or PNG, and try again.

Padding values out of range

• Explanation: The width_pad or height_pad values are set outside the allowed range.
• Solution: Adjust the padding values to be within the specified range of 0.0 to 100.0.
