Everyday scenes in 4D

Professor of Computer Science Noah Snavely, from Cornell University and his student Kevin Matzen have added a fourth dimension
of time to your system called Scene Chronology, and have collected millions of images from photo sharing sites on the Internet and views from popular sites taken from several different angles created from 3-D models combined, and the Cornell News site.
The models that have been developed to Times Square, the shopping district Akhibahara in Tokyo and 5Pointz a graffiti exhibition area in Queens, then a viewer can navigate within a virtual 3-D space while using a slider to move forward and backward in time and viewing reality in various positions.
The software works with flat surfaces in the image: signs, walls, façades or panels theater and then treats as “patches” which are stitched together to create the overall scene, the 3D effect, so it is made from a flat stage and need not be shot in 3D original, facilitating the shooting and the size of the files.
The 3-D model is then created from the global scene at a particular moment in time, the computer joins the slices that are taken from each solid in the right time and reconstructs the image for each time more simple and functional way.
The researchers who presented the model at the fair in Zurich Computer Vision, said: “when we reflect on the time of image collections, each observation has something to say,” they received the award for Best Book in the area last year.
They figure that may also change the way we think about photography, they said, and some day all photo you thought about doing, may have been made by someone.
