Processing magnetic resonance images are very complex and constantly studied by\nthe researchers to give doctors better ability to diagnose the patients. In order to\ndetect automatically suspicious regions or tumors, we present a new approach inspired\nby threshold segmentation and based on morphological operations in this paper.\nThe advantages of our approach come from the complementarities between\nthese two approaches. The morphological operations extract roughly the tumor region\nand eventually can affect healthy while the threshold segmentation method\ngives a clear picture of the structure of the different brain and therefore these two\napproaches improve significantly the threshold segmentation and detection and extraction\nof the tumor zone based on morphological operations.
