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.

    • setBasis

      void setBasis​(SteerableCoefficients coef, Kernel2D... basis)
      Compute the steerable filter.
      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.
      angle - Angle the kernel should be pointed at.
      The computed kernel. Data is recycled each time compute is called.
