质量导向算法是一种非常有效的相位解包裹算法，属于路径跟踪算法。质量导向算法的基本思想是用一幅质量图来引导相位展开，这个质量图可以用来描述包裹相位图中每个像素质量的好坏。-Quality oriented algorithm is a very effective phase unwrapping algorithm, which belongs to path tracking algorithm. The basic idea of the quality guided algorithm is to use a quality map to guide the phase unwrapping, which can be used to describe the quality of each pixel in the wrapped phase map.
