Imaging of the Lamina Cribrosa using Swept-Source Optical Coherence Tomography. [PDF]

, 2012
The lamina cribrosa (LC) is the presumed site of axonal injury in glaucoma. Its deformation has been suggested to contribute to optic neuropathy by impeding axoplasmic flow within the optic nerve fibers, leading to apoptosis of retinal ganglion cells. To

Enhanced Depth Imaging Optical Coherence Tomography: A New Way Measuring Choroidal Thickness in Pregnant Women. [PDF]

J Ophthalmol, 2017
The body changes markedly during pregnancy; each system behaves differently from a nonpregnant state. As the eyes are the only windows to see directly what is going on in the internal environment, more and more researches have been done to explain the ...

Optical clearing-aided photoacoustic microscopy with enhanced resolution and imaging depth [PDF]

, 2013
Due to strong light scattering in tissue, both the spatial resolution and maximum penetration depth of optical-resolution photoacoustic microscopy (OR-PAM) deteriorate sharply with depth.

Computational integral imaging with enhanced depth sensitivity [PDF]

Journal of Information Display, 2009
Abstract A novel computational integral imaging technique with enhanced depth sensitivity is proposed. For each lateral position at a given depth plane, the dissimilarity between corresponding pixels of the elemental images is measured and used as a suppressing factor for that position. The intensity values are aggregated to determine the correct depth

GPGPU based Depth Image Enhancement Algorithm

Journal of the Korea Institute of Information and Communication Engineering, 2013
In this paper, we propose a noise reduction and hole removal algorithm in order to improve the quality of depth images when they are used for creating 3D contents. In the proposed algorithm, the depth image and the corresponding color image are both used. First, an intensity image is generated by converting the RGB color space into the HSI color space.
