SCREENSHOTS

DYNAMIC EYE MODELING

Dynamic eye adaptation modeling refers to a system that models the human eye's reaction, and behavior to light. (Although this demo is set up for the human eye, it could easily be adapted to simulate a CCD camera for instance, which also reacts to the light in the scene)

We have all seen how the eye adapts to light situations, being blind when you walk into a movie theatre, but after a few minutes you are able to see quite a lot, or being blinded by bright light.

 

The following screenshots demonstrate a real-time implementation of this behavior, as well as the workings of my current sky-dome.

The sky-dome is also demonstrated here because in outdoor scenery, it is closely linked to the eye adaptation modeling, as the source of light..

Unfortunately the JPEG compression of these images causes banding problems to become visible, since the dither noise in the original images does not get encoded in the JPEG's. It's sufficient to say that these banding problems are not present in the actual application, or the original screenshots.

Screenshots showing off the way that the algorithm handles glare from very bright objects like the sun.

SUNRISE

A sequence of screenshots during 2 hours at sunrise. It demonstrates the working of the sky-dome, as well as the way that the eye adapts to the increasing light.

DARK ADAPTATION

A sequence of screenshots at 4:00 in the morning. The sequence starts with the eyes light adapted (a bright room etc.), and shows how the eyes adapt to the dark outside environment.

LIGHT ADAPTATION

A sequence of screenshots at 6:00 in the morning. This time we start of with the eyes dark adapted (coming from a dark room e.g. a movie theatre). It shows the way that the eyes adapts to the bright light outside.
