SEGMENT1 segments an image x by thresholding and connexity test
[zk,mk,vk,nk]=segment1(x,s);
s is a vector containing the thresholds (between 0 and 1 and increasing)
zk is the segmented image
mk,vk and nk are respectively
means, variances and number of elements in each segment.

Test:
x=shepp(256,256,1,1);s=[.2;.6];[zk,mk,vk,nk]=segment1(x,s);
figure(1),imagesc(x);axis('square');
figure(2),imagesc(zk);axis('square');
figure(3),hist(x(:));
figure(4),hist(zk(:));
figure(5),imagesc(zk==1);imagesc(zk==2);imagesc(zk==3);
