Class TrackerMedianFlow

Namespace: Emgu.CV.Legacy

Assembly: Emgu.CV.dll

Median Flow tracker implementation. The tracker is suitable for very smooth and predictable movements when object is visible throughout the whole sequence.It's quite and accurate for this type of problems (in particular, it was shown by authors to outperform MIL). During the implementation period the code at http://www.aonsquared.co.uk/node/5, the courtesy of the author Arthur Amarra, was used for the reference purpose.

Create a median flow tracker

public TrackerMedianFlow(int pointsInGrid, Size winSize, int maxLevel, MCvTermCriteria termCriteria, Size winSizeNCC, double maxMedianLengthOfDisplacementDifference = 10)

Parameters

pointsInGrid int: Points in grid, use 10 for default.
winSize Size: Win size, use (3, 3) for default
maxLevel int: Max level, use 5 for default.
termCriteria MCvTermCriteria: Termination criteria, use count = 20 and eps = 0.3 for default
winSizeNCC Size: win size NCC, use (30, 30) for default
maxMedianLengthOfDisplacementDifference double: Max median length of displacement difference
