| The project focuses on the truth and reality of the images we see. Taking any kind of video source as input, the stream's audio channel is continously played back. The corresponding frame is calculated from similarity to all previous frames. The most similar frame will be displayed. Each new frame is then placed in a database for comparison with forthcoming frames. This creates a steadily growing and learning mass which—after some time—can replace ''reality'' with frames from the past. At that point no clear distinction between reality and fiction can be made anymore. | | The project focuses on the truth and reality of the images we see.

| Similarity between frames depend on an amount of chosen factors. Most commmon are histogram, structure etc. but always depend on the features one sees as important in an image. It's not important to match the look of a frame as close as possible but to match a frame in a given set of interests.

| ===Progress===
| |
| Searching the most similar frame to the current frame in the same source doesn't work so well. In a movie the next or previous frame to the current frame is almost always the most similar one. This results in the same video delayed oen frame. Using two sources and matching source1 to source2 works better.
| |
|
| |
| Two different sources. Images are from source2, audio is from source1. Images are selected from source2 not only from similarity to the current frame of source1, but also from the overall difference to the previous frame, resulting in smoother image sequences that somtimes might be reversed. (source1 is Ger vs Aus, source2 is Ger vs Srb)

| This is the Tagesschau (tagesschau.de/download/podcast/). Source1 (Tagesschau 25.06.2010 20:00) is compared with Source2 (Tagesschau 24.06.2010 20:00). Audio is from Source1, images from Source2. Again this is similarity by distance to the previous frame.
