Class KeypointsModel

Namespace

OpenCvSharp.Dnn

Assembly

OpenCvSharp.dll

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.

Constructors

KeypointsModel(Net)

Create model from deep learning network.

public KeypointsModel(Net network)

Parameters

network Net

Net object.

KeypointsModel(string, string?)

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

public KeypointsModel(string model, string? config = null)

Parameters

model string

Binary file contains trained weights.

config string

Text file contains network configuration.

Methods

Estimate(InputArray, float)

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

public Point2f[] Estimate(InputArray frame, float thresh = 0.5)

Parameters

frame InputArray

The input image.

thresh float

minimum confidence threshold to select a keypoint.

Returns

Point2f[]

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