cell_count

mrinufft.density.cell_count(traj, shape, osf=1.0)

Compute the number of points in each cell of the grid.

Parameters:

• traj (array_like) – array of shape (M, 2) or (M, 3) containing the coordinates of the points.

• shape (tuple) – shape of the grid.

• osf (float) – oversampling factor for the grid. default 1

Returns:

• weights (array_like) – array of shape (M,) containing the density compensation weights.
