pysteps.motion.constant.constant

pysteps.motion.constant.constant(R, **kwargs)

Compute a constant advection field by finding a translation vector that maximizes the correlation between two successive images.

Parameters:

R (array_like) – Array of shape (T,m,n) containing a sequence of T two-dimensional input images of shape (m,n). If T > 2, two last elements along axis 0 are used.

Returns:

out – The constant advection field having shape (2, m, n), where out[0, :, :] contains the x-components of the motion vectors and out[1, :, :] contains the y-components.

Return type:

array_like
