Center of Mass



CENTEROFMASS finds the center of mass of the N-dimensional input array

File Information

    centerOfMass(A) finds the gray-level-weighted center of mass of the
    N-dimensional numerical array A. A must be real and finite. A warning
    is issued if A contains any negative values. Any NaN elements of A will
    automatically be ignored. centerOfMass produces center of mass
    coordinates in units of pixels. An empty array is returned if the
    center of mass is undefined.
    The center of mass is reported under the assumption that the first
    pixel in each array dimension is centered at 1.
    Also note that numerical arrays other than DOUBLE and SINGLE are
    converted to SINGLE in order to prevent numerical roundoff error.
        A = rgb2gray(imread('saturn.png'));
        C = centerOfMass(A);
        figure; imagesc(A); colormap gray; axis image
        hold on; plot(C(2),C(1),'rx')
