Abstract:
File sizes have been compared for object modeled video versus pixel-based video with respect to different factors, which influence the data rate. The goal is to simplify the choice, which representation is favorable in terms of file size for varied content. Traditional video compression is very sophisticated and to achieve even lower data rates than the state-of-the-art video codecs while preserving the visual quality is difficult and increases the complexity. Using the object-based representation, possibilities to reduce the amount of data to be stored or transferred are investigated. With our improved object-based encoder a data rate reduction of 67,6-90 percent compared to an uncompressed object-based representation and up to 90.5 percent compared to high quality, variable bitrate, pixel-based video is achieved for the investigated scenarios.
