- Category: ControlNet Preprocessors/Faces and Poses Estimators
- Output node: False
- Repo Ref: https://github.com/comfyanonymous/ComfyUI

AnimalPosePreprocessor节点专门用于检测和分析图像中的动物姿态。它利用先进的姿态估计技术来识别和处理动物形象，旨在提供详细的姿态信息，以供进一步分析或处理。

# Input types
## Required
- image
    - 需要进行动物姿态检测的输入图像。这是姿态估计过程的主要输入。
    - Comfy dtype: IMAGE
    - Python dtype: numpy.ndarray
## Optional
- bbox_detector
    - 指定用于识别图像中存在动物的感兴趣区域的边界框检测器模型。这一步对于缩小姿态估计的区域范围至关重要。
    - Comfy dtype: COMBO[STRING]
    - Python dtype: str
- pose_estimator
    - 定义用于分析图像中检测到的动物形象的姿态估计模型。这个参数决定了姿态检测的准确性和有效性。
    - Comfy dtype: COMBO[STRING]
    - Python dtype: str
- resolution
    - 设置姿态检测过程的分辨率。较高的分辨率可能导致更详细的姿态估计，但可能需要更多的计算资源。
    - Comfy dtype: INT
    - Python dtype: int

# Output types
- image
    - 返回处理后的图像，其中突出显示了检测到的动物姿态，便于对姿态估计结果进行视觉检查和分析。
    - Comfy dtype: IMAGE
    - Python dtype: numpy.ndarray
- pose_keypoint
    - 输出检测到的动物姿态的关键点，提供详细的姿态结构信息，以供进一步分析或处理。
    - Comfy dtype: POSE_KEYPOINT
    - Python dtype: Dict
- ui
    - 提供一个用户界面组件，显示检测到的动物姿态的JSON表示，为可视化和理解姿态数据提供了一种便捷的方式。
