The program does a forward pass line by line through the entire image. Each cell in the foreground is assigned the same label value as cells in its neighborhood. If there is no label among the cells in its neighborhood, a new label value is assigned to the cell. This means that this cell belongs to a different connected component. We set up an equivalence table for each label to indicate the equivalence of the labels stored in the table. After the forward pass goes through the entire image, we merge the different connected components corresponding to the equivalence labels in the table. We implement this strategy in function GenerateData().
There are two options in the program. 1. Take an nD binary image as input, and produce an nD gray image, where intensity indicates label assigned to a connected component. 2. Take an nD binary image and a set of seed points as input, and output an nD binary image containing the cells connected to the seeds. For option 2, users need to assign the member variable std::list<IndexType> m_Seeds before calling function GenerateData().
