WebFor the SIFT algorithm having great computational complexity caused by too many feature points and complicated descriptors, an advanced image registration method is proposed. At first it uses SIFT to extract the feature points from two images and eliminate edge points. WebThe algorithm treats the phase-shifting values as additional unknowns, and we can determine their exact values by analyzing interference fringes using the numerical least-squares technique. A series of simulations and experiments prove that this algorithm can effectively remove strong mirror-image artifacts because it is unaffected by random …
