/** @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. |
