/** @brief Class implementing two-dimensional phase unwrapping based on @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.
