Verified usage

Verified import paths — ran on the pinned version, not inferred.

unwrap2d

✓ from unwrap import unwrap2d

✗ import unwrap

Common mistake: 'import unwrap' only gives access to unwrap package, not the function directly

unwrap3d

✓ from unwrap import unwrap3d

✗ unwrapping.unwrap3d

No submodule named unwrapping exists

Basic 2D and 3D phase unwrapping with random wrapped phase data.

import numpy as np from unwrap import unwrap2d, unwrap3d # 2D example: wrapped phase in [-pi, pi) wrapped = np.random.uniform(-np.pi, np.pi, (10, 10)) unwrapped = unwrap2d(wrapped) # 3D example wrapped_3d = np.random.uniform(-np.pi, np.pi, (5, 10, 10)) unwrapped_3d = unwrap3d(wrapped_3d)

Debug

Known issues

gotchaFunctions expect input in radians (values between -pi and pi). Using degrees or other ranges will produce incorrect unwrapping without error.

fix

Ensure input is in radians, typically by converting degrees * np.pi / 180.

affects: all

gotchaThe library does not handle NaN or Inf values. Presence of such values may cause silent failures or incorrect results.

fix

Preprocess input to replace NaN/Inf with neighboring valid values or mask them before passing to unwrap.

affects: all

deprecatedLibrary is unmaintained since 2014. No support for Python 3.x beyond early versions, and no bug fixes.

fix

Consider using alternative libraries like 'skimage.restoration.unwrap_phase' or 'np.unwrap' for simpler cases.

affects: 0.1.1
