A novel phase unwrapping method is proposed that can be used in digital holograms, magnetic resonance imaging and synthetic aperture radar interferometry. Phase often an essential task for images with periodic phases, its result directly affects the measurement precision. However, path‐independent unwrapped results generally cannot obtained owing to inconsistencies of gradients, i.e. residues. simple efficient approach provided determine connections opposite‐sign residues by analysing relationship between gradients residues’ generation. After determination connections, integrated map not crossing The has efficiently reduced computational complexity when compared traditional methods. effectiveness was proved experimental based on real simulated data.
