The Indian Express has an article about film restoration studio, Cameo, with technology developed entirely indegeneously:
Gujar, a graduate in engineering from VIT College came up with concept of developing an affordable film restoration software and studio when he was in college. “The requirement of film restoration was found out when we were studying imaging. We talked to people concerned, who endorsed the grave problem the industry was facing already. We went ahead built a few prototypes of what we thought could be done for the problem, and demonstrated it to various people in the film industry. And then we got down to the task of building the entire software required to put up a full fledged restoration studio, “elaborates Gujar.”
The technology allows tens or hundreds of computer-servers to work together, along with human assisted computers to remove damages from films. “It took us more than a year for the research and close to a year to build the technology. Pune, being a primary IT hub allowed us to find most of the required talent locally. We had IIT graduates and experts from imaging, computer vision, Linux and computer software coming together to make this first generation of the technology.
