Class TrackerKCF

Namespace: Emgu.CV

Assembly: Emgu.CV.dll

KCF is a novel tracking framework that utilizes properties of circulant matrix to enhance the processing speed. The original paper of KCF is available at http://home.isr.uc.pt/~henriques/circulant/index.html as well as the matlab implementation.

Creates a KCF Tracker

public TrackerKCF(float detectThresh = 0.5, float sigma = 0.2, float lambda = 0.01, float interpFactor = 0.075, float outputSigmaFactor = 0.0625, float pcaLearningRate = 0.15, bool resize = true, bool splitCoeff = true, bool wrapKernel = false, bool compressFeature = true, int maxPatchSize = 6400, int compressedSize = 2, TrackerKCF.Mode descPca = Mode.Cn, TrackerKCF.Mode descNpca = Mode.Gray)

Parameters

detectThresh float: detection confidence threshold
sigma float: gaussian kernel bandwidth
lambda float: regularization
interpFactor float: linear interpolation factor for adaptation
outputSigmaFactor float: spatial bandwidth (proportional to target)
pcaLearningRate float: compression learning rate
resize bool: activate the resize feature to improve the processing speed
splitCoeff bool: split the training coefficients into two matrices
wrapKernel bool: wrap around the kernel values
compressFeature bool: activate the pca method to compress the features
maxPatchSize int: threshold for the ROI size
compressedSize int: feature size after compression
descPca TrackerKCF.Mode: compressed descriptors of TrackerKCF::MODE
descNpca TrackerKCF.Mode: non-compressed descriptors of TrackerKCF::MODE
