objdetect_HOGDescriptor_new2

[32/64bit] cv::HOGDescriptor のインスタンスを生成します

objdetect_HOGDescriptor_new2 p1,p2,p3,p4,p5,p6,p7,p8,p9,p10,p11,p12

p1 = ARGS_SIZE : Size winSize
p2 = ARGS_SIZE : Size blockSize
p3 = ARGS_SIZE : Size blockStride
p4 = ARGS_SIZE : Size cellSize
p5 = int : int nbins
p6 = int : int derivAperture
p7 = double : double winSigma
p8 = int : [MarshalAs(UnmanagedType.I4)] HistogramNormType histogramNormType
p9 = double : double l2HysThreshold
p10 = int : int gammaCorrection
p11 = int : int nlevels
p12 = var : out IntPtr returnValue

解説

HOG (Histogram of Oriented Gradients) ディスクリプタとオブジェクト検出器の実装．


Navneet DalalとBill Triggsによって紹介されたHOGディスクリプタアルゴリズム[50]を使用しています．
