As the number of virtual 3D city models is steadily increasing, so are the possible applications that take advantage of them. 3D models can be used for applications that range from simple graphic visu...
This paper presents a stepwise voxel-based filtering algorithm for mobile LiDAR data. In the first step, to improve computational efficiency, mobile LiDAR points, in xy-plane, are first partitioned in...
Aimed at the global registration problem of the single-closed ring multi-stations point cloud, a formula in order to calculate the error of rotation matrix was constructed according to the definition ...
Design a calibration target that can be scanned by 3D laser scanner while shot by digital camera, achieving point cloud and photos of a same target. A method to joint calibrate 3D laser scanner and di...
The fluvial transport is an important aspect of hydrological and geomorphologic studies. The knowledge about the movement parameters of different-size fractions is essential in many applications, such...
Researchers from North Carolina State University and the University of Delaware have developed an algorithm that can quickly and accurately reconstruct hyperspectral images using less data. The images...
While 3-D printers have become relatively cheap and available, 3-D scanners have lagged well behind. Now an algorithm developed by Brown University researchers may help bring high-quality 3-D scanning...
Remotely sensed images often contain a combination of both pure and mixed pixels. Analysis and classification of remotely sensed imagery used to provide information on the spatial pattern of land co...
A high-dynamic-range liquid crystal display (HDR-LCD) which studies as a dual-panel display can much enhance the contrast ratio of image and reduce the power consumption upon the locally controlled dy...
This work examines protection of multicast sessions in optical networks utilizing a novel segment-based algorithm called Level Protection. Our proposed scheme exhibits improved performance compared to...
Without using a cyclic prefix, a DML-based 10-Gb/s OFDM at 2.5-GHz bandwidth transmission over 65-km SMF is demonstrated to be possible while maintaining the efficient throughput and short-latency tim...
We propose a modified two-stage feedforward carrier recovery algorithm for M-QAM formats that achieves a 3x reduction in computation complexity compared to a single-stage algorithm. When combining wit...
Bit-and-power-loading(BPL) [power-loading (PL)] offers the best (worst) performance.For MMFs of <300m PL is effective for escalating an optical OFDM MMF link performance to its maximum potential; for ...
We propose a novel monitor placement algorithm that reduces significantly the number of monitors required to accurately assess the QoT of all lightpaths established in an optical network, compared to ...
A novel design algorithm of PON ODN is proposed and demonstrated. Based on the forecasted demand, it can automatically generate a suboptimal network in terms of the total cable deployment construction...
