register_framedata_list

astropop.image.register.register_framedata_list(frame_list, algorithm='cross-correlation', ref_image=0, clip_output=False, cval='median', inplace=False, skip_failure=False, **kwargs)

Perform registration in a framedata list.

Parameters:

frame_listlist

A list containing FrameData images to be registered. All images must have the same shape.

algorith{‘cross-correlation’, ‘asterism-matching’} (optional)

The algorithm to compute the AffineTransform between the images. ‘cross-correlation’ will compute the transform using phase_cross_correlation method. ‘asterism-matching’ will use astroalign to match asterisms of 3 detected stars in the field and compute the transform. Default: ‘cross-correlation’

ref_imageint (optional)

Reference image index to compute the registration. Default: 0

clip_outputbool (optional)

If True, the output images will be clipped to a only-valid pixels frame.

cvalfloat or {‘median’, ‘mean’} (optional)

Fill value for the empty pixels in the transformed image. If ‘mean’ or ‘median’, the correspondent values will be computed from the image. Default: ‘median’

skip_failure: bool (optional)

If True, the images that fail to register will be skipped. Their data will be fill with the cval and all pixels mask will be set to True. If False, the error will be raised. Default: False

inplacebool (optional)

Perform the operation inplace, modifying the original FrameData container. If False, a new container will be created. Default: False

**kwargs

keyword arguments to be passed to CrossCorrelationRegister or AsterismRegister during instance creation. See the parameters in each class documentation.
