Get Kernel

Description

Reads a predefined kernel. Type : polymorphic.

Input parameters

Kernel Family : enum, determines the type of matrix. This value corresponds to the thousandth unit in the researched code.

• • Gradient : specifies the kernel family as gradient
  • Laplacian : specifies the kernel family as Laplacian
  • Smoothing : specifies the kernel family as smoothing
  • Gaussian : specifies the kernel family as Gaussian

Kernel Size (3,5,…) : integer, determines the horizontal and vertical matrix size. The values are 3, 5, and 7, corresponding to the convolutions 3 × 3, 5 × 5, and 7 × 7 supplied in the matrix catalog. This value corresponds to the hundredth unit in the researched code.
Kernel Number : integer, is the matrix family number. It is a two-digit number, between 0 and n, belonging to a family and a size. A number of predefined matrices are available for each type and size.
Kernel Code : integer, is a code you can use to directly access a convolution matrix. Each code specifies a specific convolution matrix. You can use this input if it is connected and is not 0. The kernel located in the file then is transcribed into a 2D array that is available from the output Kernel. You can use the codes to specify a predefined kernel.

Output parameters

Divider : float, is the normalization factor associated with the retrieved kernel.
Kernel : array, resulting matrix. It corresponds to a kernel encoded by a code specified from the inputs Kernel Family, Kernel Size, and Kernel Number or a from a code directly passed through the input Kernel Code. You can connect this output directly to the input Kernel in the Convolute function.
Kernel code : integer, indicates the code that was used to retrieve the kernel.
