Algorithm 1 Binary thresholding

1. START

2.   READ source image, s(x,y) where x and y denotes the pixel coordinates

3.   threshold value, t = 127

4.   maximum value, m = 255

5.   FOR pixel in s(x,y):

6.     IF s[pixel] < t:

7.       s[pixel] = 0

8.     ELSE

9.       s[pixel] = 255

10.      END IF

11.   END FOR

12. END
