__fromPtr__()

static new SparseOpticalFlow OpenCVForUnity.VideoModule.SparseOpticalFlow.__fromPtr__ ( IntPtr  addr )

static

calc() [1/2]

void OpenCVForUnity.VideoModule.SparseOpticalFlow.calc	(	Mat	prevImg,
		Mat	nextImg,
		Mat	prevPts,
		Mat	nextPts,
		Mat	status,
		Mat	err
	)

Calculates a sparse optical flow.

Parameters

prevImg	First input image.
nextImg	Second input image of the same size and the same type as prevImg.
prevPts	Vector of 2D points for which the flow needs to be found.
nextPts	Output vector of 2D points containing the calculated new positions of input features in the second image.
status	Output status vector. Each element of the vector is set to 1 if the flow for the corresponding features has been found. Otherwise, it is set to 0.
err	Optional output vector that contains error response for each point (inverse confidence).

calc() [2/2]

void OpenCVForUnity.VideoModule.SparseOpticalFlow.calc	(	Mat	prevImg,
		Mat	nextImg,
		Mat	prevPts,
		Mat	nextPts,
		Mat	status
	)

Calculates a sparse optical flow.

Parameters

prevImg	First input image.
nextImg	Second input image of the same size and the same type as prevImg.
prevPts	Vector of 2D points for which the flow needs to be found.
nextPts	Output vector of 2D points containing the calculated new positions of input features in the second image.
status	Output status vector. Each element of the vector is set to 1 if the flow for the corresponding features has been found. Otherwise, it is set to 0.
err	Optional output vector that contains error response for each point (inverse confidence).
