Moving objects classification via category-wise two-dimensional principal component analysis [PDF]

open access: yesApplied Computing and Informatics, 2022
Classifying moving objects in video sequences has been extensively studied, yet it is still an ongoing problem. In this paper, we propose to solve moving objects classification problem via an extended version of two-dimensional principal component ...

Robust Orthogonal Complement Principal Component Analysis [PDF]

open access: yes, 2016
Recently, the robustification of principal component analysis has attracted lots of attention from statisticians, engineers and computer scientists. In this work we study the type of outliers that are not necessarily apparent in the original observation ...

Sparse logistic principal components analysis for binary data [PDF]

open access: yes, 2010
We develop a new principal components analysis (PCA) type dimension reduction method for binary data. Different from the standard PCA which is defined on the observed data, the proposed PCA is defined on the logit transform of the success probabilities ...

Principal component analysis and its generalizations for any type of sequence (PCA-Seq)

open access: yesВавиловский журнал генетики и селекции, 2020
In the 1940s, Karhunen and Loève proposed a method for processing a one-dimensional numeric time series by converting it into multidimensional by shifts. In fact, a one-dimensional number series was decomposed into several orthogonal time series.

Sizing the Shape: Understanding Morphometrics [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2015
Purpose: One of the most fundamental limitations associated with the conventional cephalometrics is its inability to delineate size from shape as it depends mainly on linear and angular measurements.
