A robust approach for the detection of brain tumors by variational b-spline level-set method and brain extraction

Medical image segmentation, as an application of image segmentation, is to extract some anatomical structures from various medical image modalities. The idea is to isolate the contours of the tumor subsequently to characterize. After detecting the outline, we will have to set a margin inside and outside of the tumor. So we have a band around the tumor: a healthy part and a cancerous part. The context of our study is based particularly on the diagnosis of brain tumors.
