VII. METHODOLOGY In our research, we will also focus on similar line of implementation by finding and segregating the area of images which have tumor in it. First of all, we will fetch database of color images which have brain tumor in it. These images are process for noise removal for more accuracy by median filters. Further these images will be process with binary tree based quantization clustering process. This process will provide us the clusters to work on. Normally it distributes three clusters into shape. These clusters are process with ROI (reason of interest) technique to find the exact area to highlight and in our research case, it is tumor in brain. Finally segmentation process will be used to make it distinguish from other parts of the brain. The process by which the clusters would be formed can be explained by C ((x, - 4,)' el2 = e'R,,e Since R is symmetric, the solution is the eigenvector e, corresponding to the largest or principal eigenvector X, of R.

The total squared variation in the direction e, is therefore Once the principal eigenvector has been determined, points in C,

can be sorted into two sets C2, and C2, + I in the following way:

C2, = {s E C,: eix, I eiq,} C2n+l = {s E C,: etx, eiq,}.

Finally, the new statistics for each node may be calculated by first calculating R2,, m2,, and N2, for node 2n, and then applying the relations.

For calculation of various parameters like PSNR value and MSE value the following equations would be used:

This Research is our continuous study and we will find the better results in highlighting the tumor in the segmented portion. In this paper we have studied various techniques for merging and segmentation process in the image processing for tumor detection. This Research is still in process and experimentation in running phase to test the proposed work.
