Panorama video is becoming increasingly popular, and we present an end-to-end real-time system to interactively zoom and pan into high-resolution panoramic videos. Compared to existing systems using perspective panoramas with cropping, our approach creates a cylindrical panorama. Here, the perspective is corrected in real-time, and the result is a better and more natural zoom. Our experimental results also indicate that such zoomed virtual views can be generated far below the frame-rate threshold. Taking into account recent trends in device development, our approach should be able to scale to a large number of concurrent users in the near future.

“…Some allow coaches to list events, some make video recordings, and some capture player movements automatically. In this respect, our Bagadus system [7,13,14] allows users to mark and follow one or more players live during a game, and play out expert annotations in real-time. Nevertheless, some events end up without a tag, and identifying these often requires reviwing larger portions of the game footage.…”

Bagadus is a prototype of a soccer analysis application which integrates a sensor system, a video camera array and soccer analytics annotations. The current prototype is installed at Alfheim Stadium in Norway, and provides a large set of new functions compared to existing solutions. One important feature is to automatically extract video events and summaries from the games, i.e., an operation that traditionally consumes a huge amount of time. In this demo, we demonstrate how our integration of subsystems enable several types of summaries to be generated automatically, and we show that the video summaries are displayed with a response time around one second.

“…Multimedia information with an intuitive and friendly, wonderful and rich features, but also has the characteristics of data processing is not conducive to large, unstructured, meaning more content and so on [1]. Wherein the video information is multimedia information in the largest proportion, up to the amount of information, the most widely used application prospect of complex parts [2]. By analyzing the structure and content features sports videos automatically recognize extract highlight scenes interested viewers can save time viewers to watch sports [3].…”
