/** @defgroup phase_unwrapping Phase Unwrapping API
|
||||
|
||||
Two-dimensional phase unwrapping is found in different applications like terrain elevation estimation
|
||||
in synthetic aperture radar (SAR), field mapping in magnetic resonance imaging or as a way of finding
|
||||
corresponding pixels in structured light reconstruction with sinusoidal patterns.
|
||||
|
||||
Given a phase map, wrapped between [-pi; pi], phase unwrapping aims at finding the "true" phase map
|
||||
by adding the right number of 2*pi to each pixel.
|
||||
|
||||
The problem is straightforward for perfect wrapped phase map, but real data are usually not noise-free.
|
||||
Among the different algorithms that were developed, quality-guided phase unwrapping methods are fast
|
||||
and efficient. They follow a path that unwraps high quality pixels first,
|
||||
avoiding error propagation from the start.
|
||||
|
||||
In this module, a quality-guided phase unwrapping is implemented following the approach described in @cite histogramUnwrapping .

* This algorithm belongs to the quality-guided phase unwrapping methods.

* First, it computes a reliability map from second differences between a pixel and its eight neighbours.
|
||||
* Reliability values lie between 0 and 16*pi*pi. Then, this reliability map is used to compute
|
||||
* the reliabilities of "edges". An edge is an entity defined by two pixels that are connected
|
||||
* horizontally or vertically. Its reliability is found by adding the the reliabilities of the
|
||||
* two pixels connected through it. Edges are sorted in a histogram based on their reliability values.
|
||||
* This histogram is then used to unwrap pixels, starting from the highest quality pixel.
|
||||
|
||||
* The wrapped phase map and the unwrapped result are stored in CV_32FC1 Mat.
