navigate.model.analysis.camera.compute_flatfield_map

navigate.model.analysis.camera.compute_flatfield_map(image: Union[_SupportsArray[dtype], _NestedSequence[_SupportsArray[dtype]], bool, int, float, complex, str, bytes, _NestedSequence[Union[bool, int, float, complex, str, bytes]]], offset_map: Union[_SupportsArray[dtype], _NestedSequence[_SupportsArray[dtype]], bool, int, float, complex, str, bytes, _NestedSequence[Union[bool, int, float, complex, str, bytes]]], local: bool = False) → Union[_SupportsArray[dtype], _NestedSequence[_SupportsArray[dtype]], bool, int, float, complex, str, bytes, _NestedSequence[Union[bool, int, float, complex, str, bytes]]]

Compute the flatfield map for an evenly-illuminated set of frames from an sCMOS camera.

Parameters:
  • image (npt.ArrayLike) – ZYX image of multiple camera frames with defocused, even signal.

  • offset_map (np.ArrayLike) – XY image of camera offset in the absence of signal.

  • local (bool) – Compute the local flatfield map (as opposed to global).

Returns:

flatfield_map – XY image of flatfield map.

Return type:

npt.ArrayLike
