I am following this:
X=imread('croppedImage.jpg');
croppedImage.jpg
dimension=size(croppedImage)
% Mean M=mean2(X)
% Covariance C=(X-M)*(X-M)'
Now I do not know how to find Eigen Value and Eigen Vector from Covariance Matrix.
Please help
Also write code for this statement "Finally the Eigen vectors are arranged in such a way that the corresponding Eigen value is in the decreasing order."
Thanks!

I'd say that the image was probably converted to HSV space and they thresholded the S channel. Then took the largest blob.
