In this Letter, the character of Euclidean matrix norm (EMN) intensity difference between phase-shifting interferograms, which changes in sinusoidal form with phase shifts, is presented. Based on character, an EMN shift extraction algorithm proposed. Both simulation calculation and experimental research show that shifts high precision can be determined proposed easily. Importantly, will supply a powerful tool for rapid calibration shifts.
The cell overlapping and adhesion phenomenon often exists in image processing. Separating overlapped into single ones is of great important difficult quantitative analysis automatic recognition. In this paper, an algorithm based on concave region extraction erosion limit has been proposed to judge separate images. Experimental results show that the a good separation effects analog Then method applying actual cervical obtains result.
By combining the advantage of multi-wavelength phase-shifting interferometry and two-step phase retrieval algorithm, measured with high precision large measuring range can be retrieved rapidly from three interferograms unknown shifts recorded by a single-chip color CMOS. First, two normalized differential without backgrounds are obtained using subtraction then normalization among interferograms. Then wrapped phases single wavelength Gram-Schmidt (GS) orthonormalization approach. Finally...
Although spatially incoherent waves with various bandwidths can be utilized to perform Fresnel correlation holography (FINCH), the visual evaluation of records' quality was not well known, in this study, different were FINCH's recording and reconstruction. The obtained results showed that, like conventional digital holography, holograms resolution reconstructed images greatly associated fringe contrast FINCHps. Therefore, FINCHps should a better parameter evaluate FINCH quality. © 2015 Wiley...
