چکیده

In this paper, the image segmentation is considered as a graph partition problem and global criterion which measures both the total dissimilarity among the different groups and the total similarity inside them is proposed. An efficient method based on a generalized eigenvalue treatment is used to optimize this criterion in order to segment images. The method is applied to segment brain tumors from MRI (Magnetic Resonance Imaging) images, then providing automatically the information about tumor for helping the diagnostic. The results obtained by the proposed method are encouraging. Résumé. Dans ce papier, la segmentation d’images est vue comme un problème de partition de graphes et le critère global qui mesure à la fois la dissymilarité totale parmi les différentes groupes et la similarité totale est proposé. Une méthode efficace basée sur un traitement de valeurs propres généralisées est utilisée pour optimiser ce critère dans le but de segmenter les images. La méthode est appliquée pour segmenter les tumeurs de cerveau issus d’images à résonance magnétique, apportant ainsi automatiquement les informations sur des tumeurs afin d’aider le diagnostic. Les résultats obtenus par la méthode sont très encourageants.

Segmentation of Magnetic Resonance Brain Imaging Based on Graph Theory

Introduction: Segmentation of brain images especially from magnetic resonance imaging (MRI) is an essential requirement in medical imaging since the tissues, edges, and boundaries between them are ambiguous and difficult to detect, due to the proximity of the brightness levels of the images. Material and Methods: In this paper, the graph-base...

Automatic segmentation of glioma tumors from BraTS 2018 challenge dataset using a 2D U-Net network

Background: Glioma is the most common primary brain tumor, and early detection of tumors is important in the treatment planning for the patient. The precise segmentation of the tumor and intratumoral areas on the MRI by a radiologist is the first step in the diagnosis, which, in addition to the consuming time, can also receive different diagnoses from different physicians. The aim of this study...
