Thanks to all,
I followed your advice and I wrote another file, here is it:

function b=Vprofil(a)
Vpro=sum(a,2);
n=size(Vpro);
for j=1:1:n
for i=1:1:(size(a,1))
if Vpro(j)>=1
b(i,j)=1;
else b(i,j)=0;
end
end
end
figure, imshow(b);

results are satisfactory except that size of "b" is smaller than of "a"
b is 142x142 ans a is 142x154

Where is the error please???

It's the first thing that comes to my mind even if I know that it's completely wrong.........I feel stupid writing it :P....I'm not used to work with MatLab that's why.....

function b=Vmid(a)
[row col]=size(a);
for x=1:row
for y=1:col
if a(x,y)=1
w=y; %first white point of a band
for y=w:col
if a(x,y)=0
z=y-1; %last white point of a band
p=(w+z)/2; %position of the middle of a band
a(x,p)=0;
end
end
end
end
end

Wow, you should get used to MATLAB. Look into the diff function.
Then see where it goes positive and negative - these will be where
your data changes from black to white or white to black. Then use the
positions to set whole columns to black - no need to scan the whole
array in x and y like you did since your source data is in vertical
strips.

Thank you Image Analyst for your reply...but I couldn't find a solution...How about using the function "find" and combine it with "diff"???

My salutations
Sami.
