public class Kernel2D_F64 extends Kernel2D
This is a kernel in a 2D convolution. The convolution is performed by convolving this kernel across a 2D array/image. The kernel is square and has the specified width. To promote reuse of data structures the width of the kernel can be changed. All elements in this kernel are floating point numbers.

WARNING: Do not modify. Automatically generated by boofcv.struct.convolve.GenerateKernel2D.

    • Kernel2D_F64

      public Kernel2D_F64(int width, double[] data)
      Creates a new kernel whose initial values are specified by 'data' and 'width'. The length of its internal data will be width*width. Data must be at least as long as width*width. The offset is automatically set to width/2
      Parameters:
      width - The kernels width. Must be odd.
      data - The value of the kernel. Not modified. Reference is not saved.

    • Kernel2D_F64

      public Kernel2D_F64(int width)
      Create a kernel with elements initialized to zero with the specified 'width' and offset equal to width/2
      Parameters:
      width - How wide the kernel is.

    • Kernel2D_F64

      public Kernel2D_F64(int width, int offset)
      Create a kernel with elements initialized to zero with the specified 'width' and 'offset'.
      Parameters:
      width - How wide the kernel is.

    • wrap

      public static Kernel2D_F64 wrap(double[] data, int width, int offset)
      Creates a kernel whose elements are the specified data array and has the specified width.
      Parameters:
      data - The array who will be the kernel's data. Reference is saved.
      width - The kernel's width.
      offset - Kernel origin's offset from element 0.
      Returns:
      A new kernel.
