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()#

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

network — Net object.

KeypointsModel()#

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

model — Binary file contains trained weights.
config — Text file contains network configuration.

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

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
