pour la classe image doivent pouvoir s'appliquer 
à tout objet image, qu'il soit binaire ou graphique. 
On a ainsi identifié les propriétés ou méthodes 
suivantes: 
class image 
methods 
titre : string 
date : Date 
auteur : Personne 
theme : string 
origine : Point 
hauteur : int 
largeur : int 
superposition(image,point) : image 
juxtaposition (image, point) : image 
translation(point d origine, 
point d arrivee) : image 
rotation(centre_de_rotation, angle) : image 
zoom(image,cadre, 
facteur d agrandissement) : image 
Une image est donc définie par son titre, la date 
de la création, son auteur, son thème, son point 
d'origine qui est le coin supérieur gauche, sa 
hauteur et de sa largeur. 
La méthode superposition (image, point) 
permet la superposition de deux images 
(graphique ou binaire) en faisant concider le 
point d'origine de la seconde image avec le point 
fourni en paramètre dans la première image. La 
méthode juxtaposition (image, point) 
permet la juxtaposition de deux images 
(graphique ou binaire) en faisant coïncider le 
point d'origine de la seconde image avec le point 
fourni en paramètre dans la première image (fig. 
3 et fig. 4). La méthode translation 
(point d origine, point d arrivee) 
permet de glisser une image de son point 
d'origine jusqu'au point d'arrivée. La méthode 
rotation (centre de rotation, angle) 
permet de tourner une image selon un centre 
fourni en paramètre. Enfin, la méthode 
zoom(image,cadre,facteur d agrandisse- 
ment) permet d'agrandir ou rétrécir une partie 
d'image fixée par le cadre en fonction du facteur 
d'agrandissement.

3.2 La classe image binaire 
Dans la classe image binaire on définit les 
attributs et les méthodes applicables à toute 
image binaire. C'est une sous-classe de la 
classe image, elle hérite donc toutes les 
méthodes de cette classe : 
class image binaire Inherit image 
methods 
nombre bit par pixel : integer 
matrice pixel : array[hauteur,largeur, 
nombre bit par pixel] of 
boolean 
("detection des points de contour *) 
Det Grad(string) :image binaire 
Det Lapl(string) :image binaire 
Det Comp(string) :image binaire 
{* chainage des points de contour") 
Suivie Cont() : graphique 
Prog Dynam() : graphique 
Trans Hough() : graphique 
Relax() : graphique 
(segmentation de l'image *) 
Etiquettage pixel) : graphique 
Regroup region() : graphique 
Division regroup() : graphique 
Une image binaire consiste en une matrice de 
pixels. Chaque pixel indique la. couleur ou le 
niveau de gris d'une portion de l'image. Un pixel
