中文说明：分支截断算法计算速度快，但有时会出现分支形成的封闭区，出现解包裹错误。利用相位质量信息来指导分支设置，可以使分 支尽量设置在质量低的区域，让误差局限在最小范围内，从而获得高质量的解包裹相位。
English Description：
Branch truncation algorithm is fast in calculation, but sometimes there are closed areas formed by branches, resulting in unwrapping errors. Using the phase quality information to guide the branch setting, the branch setting can be realized
