openpiv.filters.gaussian

static filters.gaussian(u, v, size)

Smooths the velocity field with a Gaussian kernel.

Parameters :

u : 2d np.ndarray

the u velocity component field

v : 2d np.ndarray

the v velocity component field

size : int

the half width of the kernel. Kernel has shape 2*size+1

Returns :

uf : 2d np.ndarray

the smoothed u velocity component field

vf : 2d np.ndarray

the smoothed v velocity component field
