Generalized procrustes analysis (GPA) as a tool to discriminate among sheep breeds [PDF]
Abstract. Forty male lambs of five Southern Spanish breeds were used to study the effects of the breed in their sensorial characteristics. The used breeds were: Segureña, Spanish Merino, Grazalema Merino, Churra Lebrijana and Montesina breeds. Milk lambs were slaughtered at 12 kg of live weight.

Quality and Sensory Evaluation for Goat Meat Using Generalized Procrustes Analysis [PDF]
The aim of this study was to examine relationships among experts, sex, genotypes and sensory variables by Procrustes analysis. About 10 meat samples involved different genotypes and sex were evaluated by 12 expert assessors for four sensory characteristics (color, texture, taste-odor and acceptability).

Sexual Shape Variation and Allometric Effects in Guinea Pig (Cavia porcellus) Skulls [PDF]
The skull provides essential diagnostic features for species identification and sex determination. Cranial sexual dimorphism in guinea pigs (Cavia porcellus) is particularly important to understand, as these animals are frequently used in experimental ...

Weighted analysis for missing values in generalized procrustes analysis
Generalized Procrustes Analysis (GPA), a popular tool in sensory science, is generally carried out on panelist data matrices averaged over replicates. This paper addresses the problem of missing values arising when panelists miss sessions. Because this does not necessarily result in missing values in the final averaged data matrices, a weighted ...

Mandibular Shape Variation, Allometry and Modularity in Adult Mesocephalic Dogs (Canis lupus familiaris): Insights into Morphological Integration and Animal Anatomy [PDF]
The mandible of domestic dogs represents a key structure in veterinary anatomy. This study tested the hypothesis that mandibular shape variation in adult mesocephalic dogs follows a non-random modular pattern with limited allometric influence. A total of

Generalized Procrustes Analysis
Suppose Pi(i) (i = 1, 2, ..., m, j = 1, 2, ..., n) give the locations of mn points in p-dimensional space. Collectively these may be regarded as m configurations, or scalings, each of n points in p-dimensions. The problem is investigated of translating, rotating, reflecting and scaling the m configurations to minimize the goodness-of-fit criterion Σi ...

Using Generalized Procrustes Analysis for Evaluation of Sensory Characteristic Data of Lamb Meat
Generalized Procrustes Analysis (GPA) is a multivariate statistic method that is used at the evaluation of sensory analyses in the food industry. GPA provides benefit in terms of decreasing the difference between the panellists and bringing the data obtained from different panellists together. In this study, the aim was to determine the effect of a pre-

A simple alternative to generalized procrustes analysis
A statistical method for analysing sensory profiling data obtained by means of fixed vocabulary or free choice profiling is discussed. The most interesting feature of this method is that it involves only simple statistical treatment and can therefore be performed using standard software packages.

Efficient tree-structured SfM by RANSAC generalized Procrustes analysis
A tree-structured SfM by RANSAC generalized Procrustes analysis (RGPA) is proposed.RGPA is able to reliably merge multiple structures at a time and remove outliers.Quick and robust bottom-up reconstruction is achieved with a shallow tree. This paper proposes a tree-structured structure-from-motion (SfM) method that recovers 3D scene structures and ...
