Scientists have used a photo colorization tool to recreate Franz Kafka's photographs.
The famous black-and-white photographs of Abraham Lincoln are considered dirty, noisy, and have a shallow depth of field that only focuses on certain parts of his portrait.
Most black and white films before 1907 were orthochromatic, or sensitive to all visible light except warm colors such as red.
When light hits a person's skin, it is reflected, although some of it can penetrate the surface and illuminate the skin from the inside, making wrinkles and other physical features less noticeable.
However, subsurface scattering effects are not captured by orthochromatic film.
Experts have tried the techniques beforecoloring old black and white photographs. However, they did not take into account what happens to old film stock. Yes, experts can remove graininess from photos, enhance them, sharpen images, and colorize them. But these photos don't reproduce the natural light-softening effects on skin that older cameras didn't capture.
A new photo colorization tool, Time-Travel Rephotography, was developed by scientists from the University of Washington, the University of Berkeley and Google Research.
Vintage photographs show a fadedmonochromatic world due to the limited capabilities of old cameras. But a new photo colorization tool takes a step back from the past and compensates for poor image quality using AI.
The researchers used a system of artificialIntellect NVIDIA StyleGen2, trained using modern digital portraits that match the historical figure due to their rather similar appearance. The scientists then projected old photographs into the space of modern images using an artificial intelligence system to create ultra-realistic modern photographs of historical figures.
