STREET REGION DETECTION FROM NORMALIZED DIGITAL SURFACE MODEL AND LASER DATA INTENSITY IMAGE
Street region detection laser scanner data normalized Digital Surface Model intensity image image processing techniques
2014/5/8
The urban road network extraction process can be simplified by firstly detecting regions corresponding to streets, allowing a substantial reduction of the search area. As a result, the extraction proc...
Method for estimating loss over wide wavelength region of fiber cables installed in access networks
Fiber characterization
2015/6/4
We propose a simple method for estimating the loss of installed cables to expand WDM access networks. Loss at arbitrary wavelengths can be very accurately predicted from the measured loss at a few wav...
Watt-Level Bi-Doped Fiber Lasers:Breakthrough into 1300 – 1500 nm Wavelength Region
Watt-Level Bi-Doped Fiber Lasers Wavelength Region
2015/7/16
Watt-level ~20% efficiency Bi fiber lasers have been demonstrated at 1340 and 1480 nm for the first time. Optical properties of Bi-doped phosphogermanosilicate fibers depending on core composition wer...
