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

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.
