IDENTIFICATION OF LOW ACCURACY REGIONS IN LAND COVER MAPS USING UNCERTAINTY MEASURES AND CLASSIFICATION CONFIDENCE
Multispectral images Classification Uncertainty Confidence Accuracy Spatial variation
2018/11/9
The aim of this article is to assess if the data provided by soft classifiers and uncertainty measures can be used to identify regions with different levels of accuracy in a classified image. To this ...
Efficacy of iron supplementation may be misinterpreted using conventional measures of iron status in iron-depleted, nonanemic women undergoing aerobic exercise training
iron deficiency supplementation aerobic training serum ferritin body iron
2018/11/21
Background: Despite its known detrimental effects, iron deficiency remains the most common micronutrient deficiency in the world. Many interventions that aim to improve iron status involve physically ...
Temporal eating patterns: associations with nutrient intakes, diet quality, and measures of adiposity
diet quality eating occasion latent class analysis meal timing obesity
2018/11/20
Background: Some evidence suggests that higher energy intake (EI) later in the day is associated with poor diet quality and obesity. However, EI at one eating occasion (EO) is also dependent on EI at ...
Location-based similarity measures of regions
similarity matching topological relations spatial data quality aggregation generalization
2016/5/23
This paper contributes a systematic investigation of location-based similarity measures between discrete regions. It is shown that the number of measures is finite, and a complete list is presented an...
SAR IMAGE AND OPTICAL IMAGE REGISTRATION BASED ON CONTOUR AND SIMILARITY MEASURES
Contour Extraction Morphologic Methods Affine Transforms Residual Deformations Multisensor Registration Similarity Measure
2016/3/17
Image registration is concerned with the establishment of correspondence between the images of the same scene. It is a challenge problem especially when multispectral/multisensor images areregistered....
A Theoretical Analysis of Normalized Discounted Cumulative Gain (NDCG) Ranking Measures
Ranking Ranking measures NDCG Consistent Distinguishability
2016/1/23
A central problem in ranking is to design a measure for evaluation of ranking functions. In this paper we study, from a theoretical perspective, the Normalized Discounted Cumulative Gain (NDCG) which ...
EVALUATION OF THE USEFULNESS OF TEXTURE MEASURES FOR CROP TYPE CLASSIFICATION BY HYPERION DATA
Hyperspectral Texture Quantization Classification Hyperion Linear Spectral Unmixing
2015/12/28
Availability of new generation of hyperspectral sensors such as the Hyperion has lead to new challenges in the area of crop type mapping and agricultural management. Many crops like wheat and barley a...
Filtering LIDAR Points by Fusion of Intensity Measures and Aerial Images
LIDAR point data laser returns intensity aerial images returns filtering
2015/12/8
Laser return intensity, delivering the surface reflectivity information in the laser wavelength, is function of many variables and ignored in most application projects. However, by a process of SILC (...
CORRELATION OF OBJECT-BASED TEXTURE MEASURES AT MULTIPLE SCALES IN SUB-DECIMETER RESOLUTION AERIAL PHOTOGRAPHY
texture segmentation correlation multiresolution
2015/11/16
Texture measures are commonly used to increase the number of input bands in order to improve classification accuracy, especially
for panchromatic or true colour imagery. While the use of texture mea...
DATA QUALITY IN 3D: GAUGING QUALITY MEASURES FROM USERS’ REQUIREMENTS
user needs data quality quality measures 3D data mapping
2015/9/28
Producing data of known quality is an essential operation of mapping agencies such as Ordnance Survey. For these data to be of value to our customers, we need to understand what quality measures will ...
An evaluation of measures for quantifying complexity of a map
information amount complexity cartography generalisation constraints
2015/9/28
A real-time map must not be too complex. Therefore, we need measures of map complexity that could guideline
the real-time generalisation process. In this paper we evaluate measures of information am...
In the past decade, LIght Detection And Ranging (LIDAR) has been recognised by both the commercial and public sector as a reliable
and accurate technique for land surveying. However, the analysis of ...
OBJECT BASED FOREST STAND DENSITY ESTIMATION FROM VERY HIGH RESOLUTION OPTICAL IMAGERY USING WAVELET BASED TEXTURE MEASURES
segmentation stand density forest inventory wavelets very high resolution
2015/8/19
Stand density or tree density, expressed as the number of trees per unit area, is an important forest management parameter. It is used by foresters to evaluate regeneration, to assess the effect of fo...
COMPARISON OF PHOTOCONSISTENCY MEASURES USED IN VOXEL COLORING
