High-resolution digital holography utilized by the subpixel sampling method [PDF]

, 2011
A novel (to our knowledge) approach for resolution improvement in digital holography is presented in this paper. The proposed method is based on recording the incoming interference field on a complementary metal-oxide semiconductor (CMOS) camera with ...

Observation of Cosmic Microwave Background Polarization with BICEP [PDF]

, 2009
Background Imaging of Cosmic Extragalactic Polarization (BICEP) is a bolometric polarimeter that has been optimized to target the B-mode of the cosmic microwave background (CMB) polarization at degree angular scales, which is a sensitive probe of the ...

Fiber tracking in q-ball fields using regularized particle trajectories [PDF]

, 2005
Most of the approaches dedicated to fiber tracking from diffusion-weighted MR data rely on a tensor model. However, the tensor model can only resolve a single fiber orientation within each imaging voxel.

Visualization Tools for High Angular Resolution Diffusion Imaging [PDF]

, 2008
There is a major effort in medical imaging to develop algorithms to extract information from DTI and HARDI, which provide detailed information on brain integrity and connectivity. As the images have recently advanced to provide extraordinarily high angular resolution and spatial detail, including an entire manifold of information at each point in the ...
