GFL_FILTER

The GFL_FILTER structure allows to define a matrix for convolution (maximum 7x7).

typedef struct (
  GFL_INT16 Size,  
  GFL_INT16 Matrix[7*7],  
  GFL_INT16 Divisor,  
  GFL_INT16 Bias
} GFL_FILTER

Members

Size

Define the width of the matrix (maximum 7).

Matrix

Define each values fo the matrix.

Divisor

Define the divisor to apply.

Bias

Define the bias to apply.

Example

A "blur" matrix is defined like this:

Size = 3
Matrix = (1 2 1 2 4 2 1 2 1)
Divisor = 16
Bias = 0
