Abstract: Medical Image processing is one of the most challenging topics in research field. Magnetic Resonance Image (MRI) plays a major role in Medical diagnostics. This Paper Present the image segmentation, tumor detection, area calculation and stage of tumor. Fuzzy c means clustering is used for bias estimation and correction. SFCM (spatial fuzzy clustering) is proposed for image segmentation. Spatial fuzzy level set is proposed to clustering and tumor detection. The segmentation of brain MRI, tumor is detected and itís identified exact location of tumor. After level set operations, tumors appear as pure white color on pure black backgrounds. The area of tumor calculates the white pixels in binary image.

Keywords: MRI, Bias estimation, SFCM, level set method, Brain tumour.
