Orientation-dependent visibility of long thin objects in polarization-based microscopy

Study of orientation effect on nanoscale polarization in BaTiO3 thin films using piezoresponse force microscopy

We have investigated the effect of texture on in-plane sIPPd and out-of plane sOPPd polarizations of pulsed-laser-deposited BaTiO3 thin films grown on Pt and La0.5Sr0.5CoO3 sLSCOd buffered Pt electrodes. The OPP and IPP polarizations were observed by piezoresponse force microscopy sPFMd for three-dimensional polarization analyses in conjunction with conventional diffraction methods using x-ray ...

Quantitative Orientation-Independent Differential Interference Contrast (DIC) Microscopy Coupled with Orientation-Independent Polarization Microscopy.

Differential interference contrast (DIC) microscopy is widely used to observe structure and motion in unstained, transparent living cells and isolated organelles, producing a monochromatic shadowcast image of optical phase gradient. Polarized light microscopy (Pol) reveals structural anisotropy due to form birefringence, intrinsic birefringence, stress birefringence, etc. DIC and Pol complement...

Polarization microscopy for characterizing fiber orientation of ocular tissues.

Characterizing the collagen fiber orientation and organization in the eye is necessary for a complete understanding of ocular biomechanics. In this study, we assess the performance of polarized light microscopy to determine collagen fiber orientation of ocular tissues. Our results demonstrate that the method provides objective, accurate, repeatable and robust data on fiber orientation with µm-s...

Statistical Background Modeling Based on Velocity and Orientation of Moving Objects

Background modeling is an important step in moving object detection and tracking. In this paper, we propose a new statistical approach in which, a sequence of frames are selected according to velocity and direction of some moving objects and then an initial background is modeled, based on the detection of gray pixel's value changes. To have used this sequence of frames, no estimator or distribu...
