UNIWIN - Analyse Procrust\u00e9enne G\u00e9n\u00e9ralis\u00e9e<\/h2><\/div><\/div>[\/vc_column][\/vc_row][vc_row][vc_column][vc_empty_space][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]<\/p>\n

L’analyse procrust\u00e9enne g\u00e9n\u00e9ralis\u00e9e (GPA) est une technique math\u00e9matique permettant de comparer des formes. Elle est utilis\u00e9e pour d\u00e9former un objet afin de le rendre autant que faire se peut semblable \u00e0 une r\u00e9f\u00e9rence, ne laissant appara\u00eetre entre l\u2019objet et la r\u00e9f\u00e9rence que les diff\u00e9rences que les transformations (rotation, translation et mise \u00e0 l’\u00e9chelle) n’ont pu gommer. La d\u00e9formation supprime les diff\u00e9rences qui ne sont pas dues \u00e0 la forme intrins\u00e8que de l’objet. Celles qui subsistent sont donc consid\u00e9r\u00e9es objectives, et permettent d’\u00e9valuer le degr\u00e9 de ressemblance entre l’objet et la r\u00e9f\u00e9rence.<\/p>\n

Cette technique a \u00e9t\u00e9 nomm\u00e9e ainsi \u00e0 partir de Procruste, un bandit de la mythologie grecque qui for\u00e7ait ses victimes \u00e0 s’allonger sur un lit et modifiait violemment leur taille pour que celle-ci corresponde \u00e0 la taille du lit.<\/p>\n

L\u2019analyse procrust\u00e9enne g\u00e9n\u00e9ralis\u00e9e est utilis\u00e9e dans tous les champs o\u00f9 l’analyse de formes peut \u00eatre utile : analyse sensorielle, biologie, arch\u00e9ologie, m\u00e9decine.<\/p>\n

Cette proc\u00e9dure est bas\u00e9e sur le package R \u2018shapes\u2019.<\/p>\n
