We propose a new general method for segmenting brain tumors in 3D magnetic resonance images. Our method is applicable to different types of tumors. First, the brain is segmented using a new approach, robust to the presence of tumors. Then a first tumor detection is performed, based on selecting asymmetric areas with respect to the approximate brain symmetry(More)
A new method that automatically detects and segments brain tumors in 3D MR images is presented. An initial detection is performed by a fuzzy possibilistic clustering technique and morphological operations, while a deformable model is used to achieve a precise seg-mentation. This method has been successfully applied on five 3D images with tumors of different(More)
This paper introduces a novel methodology for the segmenta-tion of internal brain structures in MRI volumes in the presence of a tumor. The proposed method relies on an initial seg-mentation of the tumor. Based on the tumor's type, a set of spatial relations between internal structures, remaining stable even in presence of the pathology, is established.(More)
BACKGROUND Uterine fibroids are common benign tumors of the female pelvis. Uterine artery embolization (UAE) is an effective treatment of symptomatic uterine fibroids by shrinkage of the size of these tumors. Segmentation of the uterine region is essential for an accurate treatment strategy. OBJECTIVES In this paper, we will introduce a new method for(More)
This paper introduces a novel methodology for the segmentation of brain MS lesions in MRI volumes using a new clustering algorithm named SCPFCM. SCPFCM uses membership, typicality and spatial information to cluster each voxel. The proposed method relies on an initial segmentation of MS lesions in T1-w and T2-w images by applying SCPFCM algorithm, and the T1(More)
Handwriting analysis is useful for understanding the personality characteristics through the patterns created by the handwriting and can reveal features such as mental and emotional instability. On the other hand, it is difficult to determine the personality, especially when it is associated with the law because there is no threshold or scale being able to(More)
