Do you any time think about Illusion images, how we visualize those images ? Of course, even I never think about that, even though I have large collection of such illusions. But the interesting thing is – they have very important role in the study of human visual intelligence. Let us go some more deeper now.
There are many factors which effect our visual intelligence. You may consider the factors 3D views, surfaces, colors, motion and so on. There are many such things.
The main reason behind all these illusions is the way our intelligence works. Our brain acts like a system which keep on getting trained by every days things. When it try to interpret anything, first it consult already trained data and use that in intrepretation. This is the main reason for these effects.
