add option to compute Matrix Fourier Transform (MFT) for arrays centered:
The subroutine _shift_fft 's usage of the FFT functions requires the input arrays to be in the same endianness as the system it is running on. Most systems are little-endian. Encountered when trying to FFT-shift big-endian CRIRES arrays on a little-endian system.
Parameters: dim, inner radius, outer radius, etc
Warning: special case when inner radius is 0
Possible names:
Hello,
Small heads up in the following line:
Python-utils/vigan/optics/hexa.py
Line 586 in 5e45c4c
The function plot
of hexa.py tries to use sys
which is not defined in the function. I suspect this should be system
instead.
Cheers,
Anne-Laure
Add possibility to have a mask and support NaN values in the images
_shift_fft expects an array or list for shift_value, including in the single dimensional case. If _shift_fft is used with a scalar shift_value and a 1D array it will fail due to trying to subscript the scalar with [0].
All the routines are already written and available in SPHERE derotator tests code
Possibly keep a profile() method in imutils, but call the profile module internally.
See avigan/SPHERE#47
