BRAIN Journal-Performance Analysis of Unsupervised Clustering Methods for Brain Tumor Segmentation-Figure 3:(a) Input MR Image (b) Enhanced Image (c) Segmented Tumor (d) Located brain tumor

Figure 3 shows three different original brain MR images, contrast enhancement of the
images, segmented images using K-means algorithm and finally located tumor. Fig 1.4 shows the
performance of the unsupervised clustering methods with the no. of tumor pixels and execution
time to locate the brain tumor.
