    /** @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.
