Detailed Description

The Keypoints class works with Darknet's V3 API.

The only format currently supported is the MSCOCO-style keypoint classes with an extra "person" class appended for top-down grouping. The classes are defined as follows:

0: nose
1: left eye
2: right eye
3: left ear
4: right ear
5: left shoulder
6: right shoulder
7: left elbow
8: right elbow
9: left wrist
10: right wrist
11: left hip
12: right hip
13: left knee
14: right knee
15: left ankle
16: right ankle
17: person

Member Function Documentation

◆ annotate() [1/2]

cv::Mat Darknet::Keypoints::annotate	(	const Predictions &	predictions,
		const Skeletons &	skeletons,
		cv::Mat	mat
	)

Draw the skeletons onto the given image.

Here is the caller graph for this function:

◆ annotate() [2/2]

cv::Mat Darknet::Keypoints::annotate	(	const Predictions &	predictions,
		cv::Mat	mat
	)

Similar to the other annotate() method, but automatically calls create_skeletons().

Since: 2024-09-03

Here is the call graph for this function:

◆ create_skeletons()

Darknet::Skeletons Darknet::Keypoints::create_skeletons ( const Predictions & predictions )

Looks through the prediction results and attempts to organize each person into Skeleton.

A skeleton will always contain exactly 18 indexes. If a skeleton does not have an entry for a body part, then the index will be set to -1. Otherwise, any other values is interpreted as an index into predictions.
