DIGITAL TERRAIN FROM A TWO-STEP SEGMENTATION AND OUTLIER-BASED ALGORITHM
Digital Elevation Models DEM DTM DSM ground filter surface fitting point cloud filtering
2016/7/27
We present a novel ground filter for remotely sensed height data. Our filter has two phases: the first phase segments the DSM with a slope threshold and uses gradient direction to identify candidate g...
Signals of selection in outlier loci in a widely dispersing species across an environmental mosaic
balancing selection candidate gene
2015/12/11
Local adaptation reflects a balance between natural selection and gene flow and is classically thought to require the retention of locally adapted alleles. However, organisms
with high di...
HIERARCHICAL CLUSTERED OUTLIER DETECTION IN LASER SCANNER POINT CLOUDS
Point cloud Laser Scanner Outlier detection EMST Gabriel graph Clustering
2015/11/10
Cleaning laser scanner point clouds from erroneous measurements (outliers) is one of the most time consuming tasks that has to be done before modeling. There are algorithms for outlier detection in di...

Point cloud Laser Scanner Outlier detection
2015/8/24
Outlier detection in laser scanner point clouds is an essential process before the modelling step. However, the number of points in the generated point cloud is in the order of million points, so (sem...
ON OUTLIER DETECTION IN A PHOTOGRAMMETRIC MOBILE MAPPING DATASET
Mobile Mapping relative orientation outlier detection robust statistical RANSAC Forward Search
2015/4/1
Various types of technology are used for Terrestrial Mobile Mapping (TMM) such as IMU, cameras, odometers, laser scanner etc., which are integrated in order to determine the attitude and the position ...
OUTLIER DETECTION FOR FACTORIZATION-BASED RECONSTRUCTION FROM PERSPECTIVE IMAGES WITH OCCLUSIONS
Vision Detection Reconstruction
2015/3/24
This paper proposes a method for outlier detection in recovery of projective shape and motion from multiple images
by factorization of a matrix containing the images of all scene points. Compared to ...
SPATIAL ANALYSIS FOR OUTLIER REMOVAL FROM LIDAR DATA
Spatial analysis Cross-validation LiDAR Outlier detection
2014/12/1
Outlier detection in LiDAR point clouds is a necessary process before the subsequent modelling. So far, many studies have been done in order to remove the outliers from LiDAR data. Some of the existin...
苹果内部品质近红外光谱检测的异常样本分析（Outlier Sample Analysis on Near Infrared Spectroscopy Determination for Apple Interior Quality）
苹果 无损检测 异常样本 近红外光谱
2010/2/26
应用声光可调谐滤光器近红外光谱仪检测苹果内部品质（可溶性固形物含量、总糖、总酸和硬度）时，综合利用Cook距离、马氏距离、杠杆值和学生化残差，判断疑似异常样本点，然后用二审剔除判别法确定异常样本点。最终可溶性固形物含量、总糖、总酸模型都剔除了11个异常样本，硬度模型剔除了6个异常样本。其偏最小二乘回归模型的相关系数分别从0.868、0.791、0.443、0.693提高到0.904、0.849、0...
用SVM方法研究one-class和outlier问题.在将one-class问题理解为一种函数估计问题的基础上，作者首次定义了η-one-class和η-outlier问题的泛化错误，进而定义了线性可分性和边缘，得到了求解one-class问题的最大边缘、软边缘和ν-软边缘算法.这些学习算法具有统计学习理论依据并可归结为求解线性规划问题.算法的实现采用与boosting类似的思路.实验结果表明该...
