Interface SteerableKernel<K extends Kernel2D>

All Known Implementing Classes:

SteerableKernel_F32, SteerableKernel_I32

public interface SteerableKernel<K extends Kernel2D>

Computes a 2D kernel for an arbitrary angle using steerable filters. Steerable functions can be computed from a linear combination of rotated basis kernels.

Method Detail

setBasis

void setBasis(SteerableCoefficients coef,
              Kernel2D... basis)

Compute the steerable filter.

Parameters:

coef - Coefficients for each basis.

basis - Kernels which form the basis for the steerable filter.

compute

K compute(double angle)

Computes the kernel at the specified angle.

Parameters:

angle - Angle the kernel should be pointed at.

Returns:

The computed kernel. Data is recycled each time compute is called.

getBasisSize

int getBasisSize()

getBasis
