Sir can you please tell me how to find centre and hand extremeties of hand image. I have attached the respective image here. Actually I want to automatically extract the region of vein patterns from the back of the palm. Please help me with the code.

I answered that below.

I = imread('0002.png'); [L,N] = superpixels(I,1000); BW = boundarymask(L); % imshow(imoverlay(I,BW,'cyan'),'InitialMagnification',100)

    figure
    % Define centroid 
    Ibw = im2bw(I);
    Ibw = imfill(Ibw,'holes');
    Ilabel = bwlabel(Ibw);
    stat = regionprops(Ilabel,'centroid');
    [L,N] = superpixels(I,500)
    BW = boundarymask(L);

    imshow(imoverlay(I,BW,'cyan'),'InitialMagnification',100);  hold on;
    for x = 1: numel(stat)
        plot(stat(x).Centroid(1),stat(x).Centroid(2),'ro');
    end

There are 3 hand segmentation apps on Dirk's File Exchange page that looks like they will help you: http://www.mathworks.com/matlabcentral/fileexchange/index?term=authorid%3A29180

Remove the clutter, like hang a sheet or cyc behind the person.
