Fig. 8From: Reversible data hiding for binary images based on adaptive overlapping patterna Tian’s method: unit1 and unit2 have no overlapping part. b Thoid’s method: unit1 contains pixel 1, pixel 2, pixel 3, and pixel 4. Unit2 contains pixel 3, pixel 4, pixel 5, and pixel 6. Therefore, pixel 3 and pixel 4 are overlapping pixelsBack to article page
