openpiv.filters.gaussian

openpiv.filters.gaussian(u: numpy.ndarray, v: numpy.ndarray, half_width: int = 1) → Tuple[numpy.ndarray, numpy.ndarray]

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
• half_width (int) – the half width of the kernel. Kernel has shape 2*half_width+1, default = 1

Returns:

• uf (2d np.ndarray) – the smoothed u velocity component field
• vf (2d np.ndarray) – the smoothed v velocity component field
