1+1= 1

 The picture is very interesting!

  Stereo vision produces new illusory contours.

  One of the winner from "6th Annual Best Visual Illusion of the Year".

 Design by Davi Geiger & Hiroshi Ishikawa.

  

The perception of the Kanizsa illusory triangle (first row) is strengthened by stereo matching. Does stereo matching use illusory contours as features for matching? Does stereo matching produces new illusory contours?
Stereo vision may not match illusory contours and (new) Illusory contours can be formed after stereo matching occurs (second row).

so,i call it "1+1= 1" lol

I think maybe it is hint something about a new space that could be created by our eyes in this ways?  Coooool ?  I don't know.. let me keep thinking.

Mind Frame

Afterimage Mind Frame' is a visual installation where the audience discovers and recreates images in empty picture frames. Physical, mental, and emotional interaction all come together in this piece.
The work called "Mind Frame" which was made by korea artist Jaewook Shin.

The visitor is invited to hang any of five frames on a wall. In each, they see an abstract moving image composed of white dots. After the array of dots stops moving, an afterimage of a familiar painting is revealed in the otherwise blank frame. 

The moving dots create a more complex afterimage, 'exposing' the eye like a camera to create darker and more vivid areas. The most fascinating part of this phenomenon is that they don't see just the afterimage, but a combination of the afterimage and the original painting from their own memory.

This is rare work so far i found made by afterimage.

The boundary's of science and art are blurring?

It is really coincident !
Before i choose my subject "afterimage" i use Olafur Eliasson's work ---"The weather project" as my favorite architecture in 5 things.
Anyway, the coincidence is when i search informations about afterimage, i found a video which is a short presentation by Olafur Eliasson again. 
His talk is.....a little bit boring but helpful for me.



Olafur Eliasson: Playing with space and light.

An illusion room

The famous space called:  Ames room.
It is created by an American ophthalmologist Adelbert Ames, Jr. (1880–1955), who first constructed such a room in 1946. And his idea was come from a concept by the German physicist Hermann Helmholtz in the late 19th century.An Ames room is depicted in the 1971 film adaptation of the Roald Dahl novel Charlie and the Chocolate Factory. Also, production of The Lord of the Rings film trilogy used several Ames room sets in Shire sequences to make the heights of the hobbits correct when standing next to Gandalf.


The Ames room looks cubic when seen with one eye through a specially-positioned peephole.

                                         


However, the room's true shape is trapezoidal. " The floor, ceiling, some walls, and the far windows are trapezoidal surfaces; the floor appears level but is actually at an incline (one of the far corners being much lower than the other); and the walls are slanted outward, though they seem perpendicular to the floor. This mistaken shape makes it look as if people or objects grow or shrink as they move from one corner of the room to another. "

A video about George Rousse

George Rousse, a French photographer.
His work is could be called anamorphic art, only viewable in its intended focus from one precise viewpoint. It's no business about after image or optical illusion but quite interesting. Maybe i can get some inspirations from him.

Let's have a look~!
