Detailed Description

This class represents high-level API for keypoints models.

KeypointsModel allows to set params for preprocessing input image. KeypointsModel creates net from file with trained weights and config, sets preprocessing input, runs forward pass and returns the x and y coordinates of each detected keypoint

Constructor & Destructor Documentation

KeypointsModel() [1/2]

cv::dnn::KeypointsModel::KeypointsModel	(	CV_WRAP_FILE_PATH const String &	model,
		CV_WRAP_FILE_PATH const String &	config = "" )

Python:
	cv.dnn.KeypointsModel(	model[, config]	) ->	<dnn_KeypointsModel object>
	cv.dnn.KeypointsModel(	network	) ->	<dnn_KeypointsModel object>

Create keypoints model from network represented in one of the supported formats. An order of model and config arguments does not matter.

Parameters

[in]	model	Binary file contains trained weights.
[in]	config	Text file contains network configuration.

KeypointsModel() [2/2]

cv::dnn::KeypointsModel::KeypointsModel

(

const Net &

network

)

Python:
	cv.dnn.KeypointsModel(	model[, config]	) ->	<dnn_KeypointsModel object>
	cv.dnn.KeypointsModel(	network	) ->	<dnn_KeypointsModel object>

Create model from deep learning network.

Parameters

[in]

network

Net object.

Member Function Documentation

estimate()

std::vector< Point2f > cv::dnn::KeypointsModel::estimate	(	InputArray	frame,
		float	thresh = 0.5 )

Python:
	cv.dnn.KeypointsModel.estimate(	frame[, thresh]	) ->	retval

Given the input frame, create input blob, run net.

Parameters

[in]	frame	The input image.
	thresh	minimum confidence threshold to select a keypoint

Returns

a vector holding the x and y coordinates of each detected keypoint
