Abstract :Bu çalışmada imge bölütleme problemi Mumford-Shah enerji enazlama problemi şeklinde ifade edilmiş, problemin çözümü için getirilen öneriler incelenmiş ve seçilen çözüm yöntemi uygulanıp, algoritma, doku anomalileri içeren örnek beyin manyetik rezonans insert ignore into journalissuearticles values(MR); imgeleri üzerinde değerlendirilmiştir. Uygulamalarda kullanılan örnek imgeler, beyin tümörüne bağlı ödem oluşumu ve multiple sclerosis insert ignore into journalissuearticles values(MS); lezyonları bulunduran imgeler arasından seçilmiştir. Elde edilen sonuçlar her iki durum için de sayısal ve görsel olarak sunulmuş, sonuçlar niteliksel ve niceliksel anlamda değerlendirilmiştir.     Abstract In this study, image segmentation problem is expressed in terms of Mumford-Shah energy minimization problem, several solution proposals for the problem are investigated, chosen method of solution is implemented, and the algorithm is evaluated using brain magnetic resonans insert ignore into journalissuearticles values(MR); images which contain tissue abnormalities. Sample images used in the experiments are chosen among the ones which contain oedema formation due to brain tumor, and multiple sclerosis insert ignore into journalissuearticles values(MS); lesions. Gathered results are presented in both visual and numerical forms for both cases, results are evaluated qualitatively and quantitatively.
