currently my project is video processing and my problem is im trying to find white pixel of every row[[5X5] in the region of interest(ROI) that i assigned in my binary images.so that i can know if there is a pixel detected in that row. if it detected = 1, if not = 0.
can anyone help me please :(

Sample data:
X = rand(5)>0.8;
Check if any pixel is 1
if any(X(:))
% do something
end

hi thorsten. now i want to find accuracy(100%).for example my roi size is 241x77.if all columns(77) detect 1 instead of 0 then i say its 100%. so i use yy= find(ROI_2(:,end)==1) to know which column has 1.
