Generalized procrustes analysis of coffee brands tested by five European sensory panels

Food Quality and Preference, 1998
Abstract Generalized Procrustes analysis has been applied to mean panel data from five European panels regarding the sensory characteristics of eight coffee samples. Each of the panels used its own set of attributes. The average product configuration accounted for 92% of the variation in the individual (panel) configurations.

A NEW SIGNIFICANCE TEST FOR CONSENSUS IN GENERALIZED PROCRUSTES ANALYSIS

Journal of Sensory Studies, 1992
ABSTRACT.Generalized Procrustes Analysis is frequently used to find a consensus from sensory panel data. Recently King and Arents (1991) have proposed a goodness of fit of the consensus configuration based on Monte‐Carlo simulations. A modified test is developed that retains the original assessor configurations by permutation of the data rows.

EM-GPA: Generalized Procrustes analysis with hidden variables for 3D shape modeling

Computer Vision and Image Understanding, 2013
Aligning shapes is essential in many computer vision problems and generalized Procrustes analysis (GPA) is one of the most popular algorithms to align shapes. However, if some of the shape data are missing, GPA cannot be applied. In this paper, we propose EM-GPA, which extends GPA to handle shapes with hidden (missing) variables by using the ...

Generalized Procrustes Analysis for Multilingual Studies

, 2019
When the aim is to study the differences among cultures, the comparative cultural studies assume considerable importance. One of the most peculiar aspects of a culture is definitely the language as a medium of communication between people. In the literature of cross language analyses, many approaches have been proposed for comparing two languages. They

Global optimization for optimal generalized procrustes analysis

CVPR 2011, 2011
This paper deals with generalized procrustes analysis. This is the problem of registering a set of shape data by estimating a reference shape and a set of rigid transformations given point correspondences. The transformed shape data must align with the reference shape as best possible. This is a difficult problem.

3D Model Registration by Generalized Procrustes Analysis

2019
Photogrammetric computer vision techniques and laser scanning systems can directly provide 3D models of real objects by automatically or selectively sampling the positions of a set of representative surface points. Depending on the dimension and on the shape complexity of the geometric entity under study, its complete survey often requires a multiple ...

Shape analysis using generalized procrustes analysis on Active Appearance Model for facial expression recognition

2017 International Conference on Electrical Engineering and Computer Science (ICECOS), 2017
Facial expression recognition is an active research area in the field of signal social processing. The goal is to distinguish human emotion. The problem is similar emotion, variation of emotion, and independent object through face image. The existing research using various method for modeling human facial to entirely describe facial expression through ...
