Rectangular-to-polar algorithm with phase unwrapping

Phase Unwrapping PU is reconstruction of absolute phase data from its wrapped phase. The absolute phase cannot be extracted from the wrapped phase data directly. Without phase noise, singularity, and aliasing problems, the phase information can be ...

Phase unwrapping algorithms play an important role in noncontact optical profilometries such as phase-measuring profilometry. The depth information of the measured object is implicitly defined by certain trigonometric equations derived from image data. ...

This work addresses the derivation of the phase difference-based maximum likelihood (ML) phase unwrapping algorithm. To this end, we derive the joint statistics of the phase differences on a two-dimensional grid for the multichannel case, where several ...
