นอกจากนี้ดูภาพวาดนี้ที่ฉันทำใน MS Paint ... มันช่างน่ากลัวและค่อนข้างไม่สมบูรณ์ แต่ขึ้นอยู่กับรูปร่างและสีเพียงอย่างเดียวคุณสามารถเดาได้ว่ามันน่าจะเป็นอะไร โดยพื้นฐานแล้วสิ่งเหล่านี้เป็นเพียงสิ่งเดียวที่ต้องรบกวนการสแกน เมื่อคุณดูรูปร่างที่โดดเด่นและการผสมผสานของสีที่ใกล้เคียงมันจะเป็นยังไง? บิตที่ฉันไม่ได้ทาสีพื้นหลังสีขาวควรถูกพิจารณาว่าเป็น "อะไรที่ไม่สอดคล้องกัน" ถ้ามันมีพื้นหลังโปร่งใสมันสามารถไปได้เกือบทุกภาพอื่น ๆ และคุณยังสามารถเห็นมันได้
