Performance Analysis of Color Based Region Split and Merge and Otsu’s Thresholding Techniques for Brain Tumor Extraction

A brain tumor is a solid mass of abnormal cells within the brain.It is a set of some tissues that occur due to the rise of uncontrolled cell division. The work forms an image processing pipeline, consisting of noise reduction, feature extraction by image segmentation morphological operations to extract the region of interest. The work is based on the simultaneous use of two segmentation techniques, CB region split and merge segmentation and Otsu’s Thresholding to extract the area of brain containing tumor from the magnetic resonance imaging (MRI) of brain.It has been observed that the otsu’s thresholding technique gives a better performance in terms of accuracy and diagnosing the complete tumor region from the MRI. The results of this study are
