CA 2130340

The present invention provides a method for identifying the size, shape, and location of objects (200, 202, 204, 206) in a specimen wherein the image of the specimen is represented by image data (100) and wherein the image data (100) is processed to provide mask data representing a mask (316) wherein the mask identifies the size, shape, and location of the object. Generally, the method includes the step of enhancing the image (102) and creating a threshold image (104, 304, 610) wherein the threshold image (104, 304, 610) includes a threshold intensity value (510) associated with each pixel of the image. The threshold image (610) is combined (506) with the original image (100) to provide a mask image that identifies the size, shape, and location of the objects. The mask image may be further reamed (106) to ensure accurate identification of the object (200, 202, 204, 206). Various other techniques are disclosed within the general method for processing image data (100).

Procédé d'identification de la taille, de la forme et de l'emplacement d'objects (200, 202, 204, 206) dans un spécimen, l'image du spécimen étant représenée par des données d'image (100) et les données d'image (100) étant traitéss de manière à fournir des données représentant un masque (316) identifiant la taille, la forme et l'emplacement de l'objet. En général, le procédé consiste à améliorer l'image (102) et à créer une image seuil (104, 304, 610) comprenant une valeur d'intensité de seuil (510) associée à chaque pixel de l'image. On combine (506) l'image seuil (610) avec l'image originale (100) pour obtenir une image de masque qui identifie la taille, la forme et l'emplacement des objets. On peut encore détourer (106) l'image de masque pour garantir une identification précise de l'objet (200, 202, 204, 206). On décrit différentes autres techniques relatives au procédé général de traitement de données d'image (100).
