London: With a new technology cellphone users will be able to combine different videos from the same scene and make it into a more detailed footage to stream the video live to the web. This new system was developed by a team of Microsoft researchers based in Cairo.
The new technology called Mobicast uses two sets of software - one for smartphones using the Windows Mobile operating system and other for a server receiving the video streams, reports ANI. When different phones with the software start streaming video, they synchronize their clocks with the server, which then uses timestamps on the footage to align video frames in time. Then image-recognition technology gauges how footage physically overlaps: features such as edges and corners are used to find areas that match, before the images are blended to create a wider view of the scene.
Though, the technology can revolutionize the use of cellphone cameras, it has its own challenges to overcome. "The number of users of these services is growing fast but there's a catch," New Scientist quoted Ayman Kaheel, who developed the new system as saying. He added that the limitations of cellphone hardware and mobile-network capacity make for relatively low-quality footage.
Normally, mobile phone users make use of services like Qik and Ustream to stream video live to the web. According to Bhaskar Roy, Co-founder of Qik, the newly developed technology has the potential to enhance services like his own. "Think of somewhere where there will be a lot of people capturing video on phones, like a sporting or breaking news event," he said.
