C(i, 3) - the error distribution function with I rows and J columns 1. Set Ep(m, n) = Eg(m, n) = 0 for R rows and C columns 2. loop m=1,R 3. loop n=1,C 4. Calculate the total propogated error at (m,n) due to prior assignments Ep (m,n) = > J E CijEg ((m-(+1). (n-/+1)) Equation 2 5.Sum the current pixel value and the total propogated error: T = I(m,n) + Ep(m,n) 6. IF T threshold THEN do steps 7. and 8. ELSE. do steps 9. and 10. 7. Set pixel (m,n). on B. Calculate error generated at current location Eg(m,n) = T - 2*threshold 9. Set pixel (m,n) off 10. Calculate error generated at current location Eg(m, n) = threshold
