A SIMPLE INTERPRETATION OF THE RICE SPECTRAL INDICES SPACE FOR ASSESSMENT OF HEAVY METAL STRESS
Heavy metal stress Hyperspectral data Spectral indices space Visualization Rice
2016/11/23
Heavy metal stress will induce the change of the bio-parameters like chlorophyll, nitrogen and water content of rice. In this paper, we analyzed the traditional spectral index which has strong relatio...
GEOMETRIC QUALITY ASSESSMENT OF LIDAR DATA BASED ON SWATH OVERLAP
Lidar Quality Geometry Relative Accuracy
2016/7/4
This paper provides guidelines on quantifying the relative horizontal and vertical errors observed between conjugate features in the overlapping regions of lidar data. The quantification of these erro...
NUMERICAL ANALYSIS OF WHISKBROOM TYPE SCANNER IMAGES FOR ASSESSMENT OF OPEN SKIES TEST FLIGHTS
Scanner Thermal Image Interpretation Measurement Geometry
2015/12/26
Nowadays, Open Skies uses mainly whiskbroom type thermal scanners, which provide images in the 3-5μm and 8-12μm ranges.This way of acquiring images introduces commonly known geometrical errors. They r...
An Accuracy Assessment Measure for Object Based Image Segmentation
Segmentation ASTRO BerkeleyImageSeg Ecognition Definiens
2015/12/17
Traditional approaches to accuracy assessment are inadequate for object oriented image processing. We tested some measures to assess the accuracy of object based image segmentation in a supervised con...
