This paper proposes a non-orthogonal view iris recognition system comprising a new iris imaging module, an iris segmentation module, an iris feature extraction module and a classification module. A dual-charge-coupled device camera was developed to capture four-spectral (red, green, blue, and near-infrared) iris images which contain useful information for simplifying the iris segmentation task. An...
Optical coherence tomography (OCT) is a rapidly emerging imaging modality that can provide non-invasive, cross-sectional, high-resolution images of tissue morphology in situ and in real-time. Previous studies have demonstrated that OCT can non-invasively visualize the pathological changes in the living kidney in real-time using the Munich-Wistar rat model. In this work, we demonstrate, for the first...
We present the application of optical coherence tomography (OCT) for non-destructive imaging and quantitative characterization of the macroporous cyclic acetal hydrogel cell scaffolds. High-resolution OCT visualizes the microstructures of the tissue engineering scaffolds in three-dimension. The porosity, pore size, and the interconnectivity of the hydrogel scaffolds were characterized quantitatively...
