Constructor Details

OrientationIntegralBase

protected OrientationIntegralBase(double objectRadiusToScale,
 int sampleRadius,
 double period,
 int kernelWidth,
 double weightSigma,
 boolean assignDefaultRadius,
 Class<II> integralType)

Configure orientation estimation.

Parameters:

sampleRadius - The radius of samples that it will do. Typically 6.

period - How often the image is sampled in pixels at canonical size. Internally, this value is scaled by scaledPeriod = period*objectRadius/sampleRadius. Typically 1.

kernelWidth - How wide of a kernel should be used to sample. Try 4

weightSigma - Sigma for weighting. Set to zero for unweighted, negative to use sampleRadius.

assignDefaultRadius - If true it will set the object's radius to a scale of 1
