i want find the top most pixel of binary image and then colorful it.
if the coordinate of this pixel be [i j] then the plot of this point is differnt of top pixel

i use this code

I=imread(path);
image = im2bw(I,1);

left=[0 0];
top=[0 0];
right=[0 0];
bottom=[0 0];

[row col]=size(image);


for i=1:row
for j=1:col
if( image(i,j)==0 )
left=[i j];
break;
end
end
if( top ~= [0 0])
break;
end
end

imshow(image);
hold on;
plot( top(1),top(2) ,'r*');
