void firevision::FilterLaplace::calculate_kernel | ( | int * | kernel, |
float | sigma, | ||
unsigned int | size, | ||
float | scale | ||
) | [static] |
Calculate a Laplacian of Gaussian kernel.
The kernel is calculated with the formula
kernel | buffer contains kernel upon return |
sigma | sigma for formula |
size | kernel is of quadratic size ![]() |
scale | scale parameter in formula |
