Brain tumor segmentation using cluster ensemble and deep super learner for classification of MRI

The Accurate segmentation and classification takes place a major role in the medical image processing to detect and locate the abnormal tissue region. In this, the three different types of brain magnetic resonance imaging (MRI) image source such as Type-1, Type-2 and Fluid attenuated inversion recovery are combined by the image registration process to detect the clear region of the tumor tissue since, the region of interest identification in the single image data contains less key points to define it. In this paper, we implement the ensemble technique of image segmentation to segment the tumor region of the brain MRI image. For the segmentation process, the images are pre-processed by Laplacian cellular automata filtering method and segmented by ensemble of different clustering method such as K-means, fuzzy based clustering, self-organization map (SOM) and ensemble of Gaussian mixture model, K-means, SOM and their results are compared. This ensemble cluster label is consider as the segmented result and classify the abnormalities by using deep super learning method. The experimental results and the comparison charts defines the performance rate of proposed method comparing to the other state-of-art methods. The average accuracy for the proposed work is 98% in Ensemble 1 and 97% in Ensemble 2 methods for the BraTS brain image dataset.
