ComfyUI Node: Is only trouser v4.7.3

Is only trouser v4.7.3:

The tri3d_is_only_trouser node is designed to analyze a given pose JSON file to determine if the image primarily depicts trousers, without any upper body parts like the face or shoulders. This node is particularly useful in scenarios where you need to filter images based on their content, specifically focusing on lower garments. By examining keypoints associated with facial and shoulder features, the node assesses whether these points are absent or negative, indicating that the image is likely a bottom shot, focusing solely on trousers. This functionality is beneficial for applications in fashion technology, virtual fitting rooms, or any AI-driven image processing tasks where distinguishing between upper and lower body garments is crucial.

Is only trouser v4.7.3 Input Parameters:

pose_json_file

The pose_json_file parameter is a string that specifies the path to the JSON file containing pose data. This file should include keypoints that represent various parts of the body, such as the nose, eyes, ears, neck, and shoulders. The node uses these keypoints to determine the presence or absence of upper body parts. The default value for this parameter is set to "dwpose/keypoints", which suggests a typical directory structure where such files might be stored. The accuracy of the node's output heavily relies on the correctness and completeness of the data in this JSON file.

Is only trouser v4.7.3 Output Parameters:

BOOLEAN

The output of the tri3d_is_only_trouser node is a boolean value. This output indicates whether the image is likely to be a bottom shot, focusing only on trousers. A True value suggests that all the keypoints associated with the face and shoulders are negative, meaning these parts are not visible in the image, thus confirming it as a trouser-only shot. Conversely, a False value indicates that some of these keypoints are present, suggesting the inclusion of upper body parts in the image.

Is only trouser v4.7.3 Usage Tips:

• Ensure that the pose_json_file is correctly formatted and contains accurate keypoint data for reliable results.
• Use this node in conjunction with other garment detection nodes to enhance the accuracy of clothing classification tasks.
