In this paper, we describe the effect of local electric field enhancement due to existence photonic edge states in a nanoplasmonic crystal. These can be excited by normal incident wave and are localized along continuous line defect, where translational symmetry is broken. The crystal formed triangular lattice SiO2 cylinders on top Ag thin films. Numerical simulations demonstrated that modes con...

Abstract Accurate nuclei segmentation, as an indispensable basis and core link for multi-cell cervical image analysis, plays important role in automatic pre-cancer detection. However, poor quality due to the uneven staining, complex backgrounds overlapped cell clusters poses a great challenge segmentation. In this paper, we propose new Selective-Edge-Enhancement-based Nuclei Segmentation method...

The measurement of modulation transfer functions (MTFs) in computed tomography (CT) is often performed by scanning a point source phantom such as a thin wire or a microbead. In these methods the region of interest (ROI) is generally placed on the scanned image to crop the point source response. The aim of the present study was to examine the effect of ROI size on MTF measurement, and to optimiz...

In order to estimate rock joint parameters, such as strikes and dips which geologists often inspect on site andlor calculate through 3D joint surface recognition by use of stereo-photo system, an image processing algorithm of joint set modeling which simply simulates their interpretation is designed. Comparing resultant parameters in Schmidt-net diagrams, it is confirmed that the algorithm base...
