【爱因斯坦还是玛丽莲梦露?图片测试你是否需要戴眼镜】从正常的距离看电脑屏幕,你看到的是谁?美国麻省理工学院的神经科学家利用大脑对清晰和模糊画面的反应差异,制作出神奇的“玛丽莲·爱因斯坦”混合画。这幅图不仅能测试你的视力,更能帮助人们对广告画面进行变革。http://www.dailymail.co.uk/sciencetech/article-3024005/Do-Albert-Einstein-Marilyn-Monroe-Hybrid-optical-illusion-reveal-need-wear-glasses.html

Who do YOU see: Albert or Marilyn? Optical illusion could reveal if you need glasses

  • Look at the hybrid image at a normal viewing distance from the screen
  • If the image of Einstein doesn't appear, it may mean you have bad vision
  • Illusion shows how we focus on different features depending on distance

‘Instead you only see general features, like the shape of mouth, nose and hair, and are left seeing Marilyn Monroe. ‘

The MIT team, led by Dr Aude Oliva, has spent over a decade creating hybrid optical illusions that show how images can be hidden with textures, words and other objects.

When you look at the image above, whose face do you see? At normal screen viewing distance you should see the face of Albert Einstein. Squint your eyes or take a few steps back from the image and Marilyn Monroe should come into view

Optical illusion: Motorcycle appears to change into a bicycle

'Marilyn Einstein' was created by superimposing a blurry picture of Marilyn Monroe over a picture of Albert Einstein drawn in fine lines.

Features with a high spatial frequency are only visible when viewing them close up, and those with low spatial frequencies are only visible at a distance.

Combining pictures of the two produces a single image which changes when the viewer moves closer or farther away from the screen.

Dr Oliva’s group say these images not only reveal vision problems, but can also highlight how the brain processes information.

In one study, participants were shown hybrid images for just of 30 milliseconds, and only recognised the low spatial resolution, or blurry, component of the image.

On the top row, up close, you can see that the man on the left is scowling, while the woman on the right has a placid facial emotion. Move back, and the faces change expressions and even genders. If you squint, blink or defocus, the angry man turns calm, and the calm woman turns angry, and male

At normal viewing distance, you may see a dolphin. But disguised within the low spatial frequency of this hybrid is a car, which you will see once you step back a few metres

But when the images were shown for 150 milliseconds, they only recognised the image that was produced in fine detail, or in high spatial resolution.

In a separate test, they were shown sad faces in high spatial resolution and angry faces in low spatial resolution. They superimposed pictures used both male and female faces.

When displayed for 50 milliseconds, participants always saw an angry face, but were unable to pinpoint the sex of the person pictured.

Dr Oliva says this shows that our brains discriminate between picking out fine detail in some situations, and broader detail in others.

The brain’s processing of fine details happens slightly later than processing other features, according to the research.

The teams believes hybrid images such as this may prove useful to advertisers who want to change how their logos appear at different distances.

It could also be used to mask text on devices so only someone viewing close up can read it. 

These images contain old fashioned maps of the distribution of cranial organs which can only be seen at close range to the image. Further away, all that will be seen are two normal port

Hybrid images can create textures with viewing distance. This picture shows an example of a woman's face that turns into a cat at close distance
