Image analysis problem

[yuvalmaimona]

i'm trying to take a photo of blood cell and paint each one with a different grey level in Matlab.
Can you help me find out what's wrong my code?

global img1 A B;
img=imread('cell.bmp');
A=size(img,1);
B=size(img,2);
c=gray(256);
img1=zeros (A,B)
val=0;

for x=1:A
    for y=1:B
        if img(x,y)==0 &&img1(x,y)==0
           val=val+1;
           seg(img,val,x,y)
        end
    end
end

max_val=val;
img1=abs(255-img1*(255/max_val));
figure(1)
subplot(2,1,1);
image(img1)
colormap(c)
subplot(2,1,2);
imhist(img1,c);


function seg(image, val, x, y)
    global img1 A B;
    img1(x,y)=val;
    for i=-1:1
        for j=-1:1
            if (x > 1 && y > 1) && (x < A && y <B)
                if img1(x+i,y+j)==0&&...
                    img1(x+i,y+i)==0
                    seg(img1,val,x+i,y+j)
                end
            end
        end
    end
end

thanks for your help!

Hi,

You give a riddle. We should try to find out what this undocumented code is supposed to do?

This takes much time and relies on guessing. So we may solve the riddle or not.
You have to prove our replies.

Why that much effort for us and for you? Why not simply give useful informations?
This also will motivate more members to reply and help you.
