Constructor Detail

OrientationIntegralBase

public OrientationIntegralBase(int radius,
                       double period,
                       int sampleWidth,
                       double weightSigma,
                       java.lang.Class<II> integralType)

Configure orientation estimation.

Parameters:

radius - Radius of the region being considered in terms of samples. Typically 6.

period - How often the image is sampled. This number is scaled. Typically 1.

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

weightSigma - Sigma for weighting. zero for unweighted.
