一种实现三种算法的一种算法，其目的是实现二维分支结构的轮廓提取

Bidimensional branching structures usually present crossings between processes, thus preventing the traditional chain-code based contour following algorithm to get across such critical regions to outline the whole structure. Three algorithms have been devised to circumnvent such a problem: - preprocessing pipeline based on Mathematical Morphology - Branches Tracking Algorithm: labels each branch as an object on its own - Branching Structure Contour Extraction Algorithm: follow the entire structure, with full admittance to the inner most regions of the structure.
