발명의 명칭: (EN) MITOTIC FIGURE DETECTOR AND COUNTER SYSTEM AND METHOD FOR DETECTING AND COUNTING MITOTIC FIGURES
(FR) DÉTECTEUR DE FIGURE MITOTIQUE ET SYSTÈME DE COMPTEUR AINSI QUE PROCÉDÉ DE DÉTECTION ET DE COMPTAGE DE FIGURES MITOTIQUES
요약서:
(EN) A method and system for detecting and counting mitotic figures in an image of a biopsy sample stained with at least one dye, includes color filtering the image in a computer process to identify pixels in the image that have a color which is indicative a mitotic figure; extracting the mitotic pixels in the image that are connected to one another in a computer process, thereby producing blobs of mitotic pixels; shape-filtering and clustering the blobs of mitotic pixels in a computer process to produce mitotic figure candidates; extracting sub-images of mitotic figures by cropping the biopsy sample image at the location of the blobs; extracting two sets of features from the mitotic figure candidates in two separate computer processes; determining which of the mitotic figure candidates are mitotic figures in a computer classification process based on the extracted sets of features; and counting the number of mitotic figures per square unit of biopsy sample tissue.
(FR) La présente invention concerne un procédé et un système de détection et de comptage de figures mitotiques sur une image d’un échantillon de biopsie coloré avec au moins un colorant, qui comprend la filtration chromatique de l’image au cours d’un processus informatique pour identifier les pixels sur l’image qui ont une couleur indiquant une figure mitotique ; l’extraction des pixels mitotiques sur l’image qui sont connectés les uns aux autres dans un processus informatique, produisant ainsi des taches de pixels mitotiques ; le filtrage des formes et le rassemblement des taches de pixels mitotiques dans un processus informatique pour produire des figures mitotiques candidates ; l’extraction de sous-images de figures mitotiques par recadrage de l’image de l’échantillon de biopsie au niveau de l’emplacement des taches ; l’extraction de deux jeux de caractéristiques des figures mitotiques candidates dans deux processus informatiques séparés ; la détermination des figures mitotiques candidates qui sont des figures mitotiques dans un processus de classification informatique basé sur les jeux de caractéristiques extraits ; et le comptage du nombre de figures mitotiques par unité carrée de tissu d’échantillons de biopsie.
