THE GEOMETRIC ACCURACY VALIDATION OF THE ZY-3 MAPPING SATELLITE [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013
ZiYuan-3 (ZY-3) mapping satellite is the first civilian high-resolution stereo mapping satellite of China. The satellite’s objective is oriented towards plotting 1:50,000 and 1:25,000 topographic maps.

Disease Mapping via Negative Binomial Regression M-quantiles [PDF]

open access: yes, 2013
We introduce a semi-parametric approach to ecological regression for disease mapping, based on modelling the regression M-quantiles of a Negative Binomial variable. The proposed method is robust to outliers in the model covariates, including those due to

COMPARISON AND ANALYSIS OF ACCURACY OF ELEVATION EXTRACTION BASED ON THE ZY-3 01 AND 02 SATELLITES STEREOSCOPIC IMAGES [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
The ZY-3 is the civil high-resolution optical stereoscopic mapping satellite independently developed by China. The ZY-3 constellation of the twin satellites operates in a sun-synchronous, near-polar, circular 505 km orbit, with a descending ...

Run-time Spatial Mapping of Streaming Applications to Heterogeneous Multi-Processor Systems [PDF]

open access: yes, 2009
In this paper, we define the problem of spatial mapping. We present reasons why performing spatial mappings at run-time is both necessary and desirable. We propose what is—to our knowledge—the first attempt at a formal description of spatial mappings for

Spatio-Temporal Super-Resolution Reconstruction of Remote-Sensing Images Based on Adaptive Multi-Scale Detail Enhancement

open access: yesSensors, 2018
There are many problems in existing reconstruction-based super-resolution algorithms, such as the lack of texture-feature representation and of high-frequency details. Multi-scale detail enhancement can produce more texture information and high-frequency

Application Mapping [PDF]

open access: yes, 2011
AbstractMapping of applications onto available hardware platforms is a key design step. We need to map applications both to processors and to particular execution times. This is feasible with appropriate scheduling techniques. Taking as many scheduling decisions as reasonable at design time enables us to provide timing guarantees.

Incremental spectral clustering and its application to topological mapping [PDF]

open access: yes, 2007
This paper presents a novel use of spectral clustering algorithms to support cases where the entries in the affinity matrix are costly to compute. The method is incremental – the spectral clustering algorithm is applied to the affinity matrix after each

JOINT CALIBRATION OF 3D LASER SCANNER AND DIGITAL CAMERA BASED ON DLT ALGORITHM [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
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 digital camera based on Direct Linear Transformation ...

Optimal Phonon-to-Spin Mapping in a system of a trapped ion

open access: yes, 2015
We propose a protocol for measurement of the phonon number distribution of a harmonic oscillator based on selective mapping to a discrete spin-1/2 degree of freedom.
