mxpi_keypointpostprocessor

Function	Inherits the image postprocessing base class, which is used to postprocess the inference output tensor of a posture detection model.
Constraints	Currently, the upstream of the plugin can only be connected to the mxpi_tensorinfer inference plugin, and only MxpiTensorPackageList can be used as the metadata input. This plugin calls the object detection base class Process API of the mxBase repository to communicate and receive the return value of the KeyPointInfo data type.
Plugin Base Class (Factory)	mxpi_keypointpostprocessor
Input/Output	Input: buffer (data type: MxpiBuffer), metadata (data type: MxpiTensorPackageList) Output: buffer (data type: MxpiBuffer), metadata (data type: MxpiPoseList)
Port Format (Caps)	Static input: {"metadata/tensor"} Static output: {"metadata/keypoint"}
Property	For details, see Table 1 and Table 2.
