Abstract-Clustering is commonly used in biomedical applications particularly for brain lumps detection in Abnormal magnetic resonance images (MRI). In terms of segmentation efficiency Fuzzy clustering using fuzzy local information C-means algorithm proved to be greater over the other clustering methodologies. Most Research in developed countries show that the number of people who have brain cancer were died due to the fact of inaccurate detection and not in time. Generally, CT scan or MRI that is directed into intracranial cavity produces a complete image of brain. This image is visually examined by the physician for detection & diagnosis of brain cancer. However this method of detection resists the accurate determination of size of lump. In addition, it also reduces the time for analysis. At the end of the process the lump is extracted from the MR image and its exact position and the shape also determined. The graph based on pixel value is drawn taking the various points from the swelled cells lies in the original position from the affected region. Here the affected region is considered as ellipsoid shape and the volumes have been calculated from it. A fuzzy level set algorithm is proposed in this paper to facilitate medical image segmentation & on this performance of evaluation of the proposed algorithm was carried.
