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...
Outlier Privacy
Outlier Privacy non-outliers
2016/1/5
We introduce a generalization of differential privacy called tailored differential privacy, where
an individual’s privacy parameter is “tailored” for the individual based on the individual’s data
an...
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...
Outlier detection in laserscanner point clouds
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...
Sex composition of children, parental separation, and parity progression: Is Finland a Nordic outlier?
Finland longitudinal population register data parental boy/girl preference parity progression separation
2014/11/26
Background: Previous studies that have studied parental gender preferences for children have analysed either divorce or parity progression. We use Finnish register data that make it possible to study ...
Outlier Detection via Parsimonious Mixtures of Contaminated Gaussian Distributions
Mixture models Model-based classification EM algorithm Contaminated Gaussian distribution Outlier detection Robust estimates Trimmed clustering
2013/6/14
For multivariate continuous data, the contaminated Gaussian distribution - having two parameters indicating the proportion of outliers and the degree of contamination - represents a convenient and nat...
Outlier Detection in Contingency Tables based on Minimal Patterns
Robust estimators Loglinear models Minimal patterns.
2012/9/19
In this paper we introduce a new technique for the detection of outliers in contingency tables. Outliers are defined with respect to classical loglinear
Poisson models. For the computations, we defin...
Estimation of the parameters of the generalized exponential distribution in the presence of one outlier generated from uniform distribution
Generalized exponential distribution uniform distribution
2010/9/26
Gupta and Kundu (1999) defined the cumulative distribution function of the generalized exponential (GE). It has many properties that are quite similar to those of the gamma distribution. This paper de...
Outlier detection and trimmed estimation in general functional spaces
Abstract Inference Data depth Outlier detection Robust statistics Stochastic processes
2010/3/9
This article introduces trimmed estimators for the mean and covariance functional
of data in general Hilbert spaces. The estimators are based on a data depth measure
that can be computed on any Hilb...
Robust Estimation of Ultrasound Pulses Using Outlier-Resistant De-Noising
Outlier-resistant estimation ultrasound pulse estimation
2010/1/6
A different approach to the problem of estimation of
the ultrasound pulse spectrum, which usually arises as a part of
ultrasound image restoration algorithms, is presented. It is shown
that this es...
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...
