Magnetic resonance imaging (MRI) is the primary source to diagnose a brain tumor or masses in the medical sciences. It is emerging to detect the tumors from the scanned MRI brain images at early stages for the best treatments. Existing image segmentation techniques, morphological, fuzzy c-means are wildly successful in the extraction region of interest (ROI) in brain image segmentation. Proper extraction of ROIs is useful for regularizing the regions of tumors from the brain image with effective binarization in the segmentation. However, the existing techniques are limiting the irregular boundaries or shapes in tumor segmentation. Thus, this paper presents the proposed work extending the FCM with the spatial correlated pixel (RSCP), known as FCM-RSCP. It overcomes the problem of irregular boundaries by assessing correlated spatial information during segmentation. Benchmarked MRI brain images are used in the experiment for demonstrating the efficiency of the proposed methodology.


Image processing methods stems from processing of images from storing, transmitting and representation for autonomous machine perception. It is widely used technique in all engineering areas including diagnosis and treatment of diseases in Medical Science. Segmentation of non trivial images is one of the most challenging task because it requires more sophisticated method to differentiate between each region. The objective of this paper is to provide comprehensive overview of various segmentation methods used for MRI brain images. Hence, study of existing algorithms is all important for achieving accuracy. First, we briefly discuss about brain tumors, imaging modalities of brain and then several segmentation algorithms surveyed in this work. Complexities of existing algorithms and the segmentation outputs and analysis has also been discussed in observations.
