A scalable architecture for uncompressed-domain watermarked videos Universiteit Gent

Hannes Mareen, Johan De Praeter, Glenn Van Wallendael, Peter Lambert
Video watermarking is a well-established technology to help identify digital pirates when they illegally re-distribute multimedia content. In order to provide every client with a unique, watermarked video, the traditional distribution architectures separately encode each watermarked video. However, since these encodings require a high amount of computational resources, such architectures do not scale well to a large number of users. Therefore, ...

Improving relevant subjective testing for validation : comparing machine learning algorithms for finding similarities in VQA datasets using objective measures Universiteit Gent

Ahmed Aldahdooh, Enrico Masala, Glenn Van Wallendael, Peter Lambert, Marcus Barkowsky
Subjective quality assessment is a necessary activity to validate objective measures or to assess the performance of innovative video processing technologies. However, designing and performing comprehensive tests requires expertise and a large effort especially for the execution part. In this work we propose a methodology that, given a set of processed video sequences prepared by video quality experts, attempts to reduce the number of subjective ...

Overview of MV-HEVC prediction structures for light field video Universiteit Gent

Vasileios Avramelos, Glenn Van Wallendael, Peter Lambert
Light field video is a promising technology for delivering the required six-degrees-of-freedom for natural content in virtual reality. Already existing multi-view coding (MVC) and multi-view plus depth (MVD) formats, such as MV-HEVC and 3D-HEVC, are the most conventional light field video coding solutions since they can compress video sequences captured simultaneously from multiple camera angles. 3D-HEVC treats a single view as a video sequence ...
