zoom1d

image_registration.fft_tools.zoom.zoom1d(inp, usfac=1, outsize=None, offset=0, nthreads=1, use_numpy_fft=False, return_xouts=False, return_real=True)

Zoom in to the center of a 1D array using Fourier upsampling

Parameters:

inpnp.ndarray

Input 1D array

usfacint

Upsampling factor

outsizeint

Number of pixels in output array

offsetfloat

Offset from center in original pixel units

Returns:

The input array upsampled by a factor usfac with size outsize.

If return_xouts, returns a tuple (xvals, zoomed)

Other Parameters:

return_xoutsbool

Return the X indices of the output array in addition to the scaled array

return_realbool

Return the real part of the zoomed array (if True) or the complex
