    We are glad to announce that our paper “Implementation-Free Forensic Watermarking for Adaptive Streaming using AB Watermarking” was accepted for presentation at the International Congress on Information and Communication Technology, in London, United Kingdom (held digitally due to the ongoing pandemic). The proceedings will be available soon here. Hannes Mareen presented his research on February 25, ...
  • Paper accepted in Electronics: Keyframe Insertion: Enabling Low-Latency Random Access and Packet Loss Repair February 11, 2021Paper accepted in Electronics: Keyframe Insertion: Enabling Low-Latency Random Access and Packet Loss Repair
    From a video coding perspective, there are two challenges when performing live video distribution over error-prone networks, such as wireless networks, namely random access and packet loss repair. There is a scarceness of solutions that do not impact steady state usage and users with reliable connections. The proposed solution minimizes this impact by complementing a ...
  • Paper accepted in IEEE TCSVT: Forensic Watermarking Fallback System December 9, 2020Paper accepted in IEEE TCSVT: Forensic Watermarking Fallback System
    Our paper, “Camcording-resistant Forensic Watermarking Fallback System using Secondary Watermark Signal,” was accepted for publication in IEEE Transactions on Circuits and Systems for Video Technology (TCSVT). Public full-text on ResearchGate. To protect movies from digital piracy, forensic watermarking is used to track down pirates when they illegally leak copyright-protected videos. That is, each legitimate user gets ...
  • Paper accepted in MTAP: Random Access Prediction Structures for Light Field Video Coding with MV-HEVC May 26, 2020Paper accepted in MTAP: Random Access Prediction Structures for Light Field Video Coding with MV-HEVC
    Our article with the title “Random access prediction structures for light field video coding with MV-HEVC” was published in Multimedia Tools and Applications. The article focuses on exploring prediction structures that can enable random access when compressing light field video with MV-HEVC. Light field video promises to deliver the required six degrees of freedom (6DoF) ...
  • Paper accepted in IEEE Access: Rate-Distortion-Preserving Forensic Video Watermarking April 1, 2020Paper accepted in IEEE Access: Rate-Distortion-Preserving Forensic Video Watermarking
    Our paper, “Rate-Distortion-Preserving Forensic Watermarking using Quantization Parameter Variation“, has been accepted for publication in IEEE Access. Watermarking enables the identification of digital pirates that illegally redistribute copyright-protected videos. One of the main challenges is for the watermark to be imperceptible, while not increasing the video bit rate. Additionally, the system should be robust to attacks ...
  • Paper accepted in IEEE Transactions on Multimedia: Representing and Coding Light Field Images and Video October 14, 2019Paper accepted in IEEE Transactions on Multimedia: Representing and Coding Light Field Images and Video
    Our paper, “Steered Mixture-of-Experts for Light Field Images and Video: Representation and Coding“, has been accepted in IEEE Transactions on Multimedia Key observations: Introduction of a novel representation method for any-dimensional image data embedded in a strong Bayesian framework Multiple short conference papers have been presented on the subject, but no full paper was yet published. Extra novelties ...
  • Paper Accepted at IEEE ICCE-Berlin 2019: Light Field Image Compression Using Versatile Video Coding (VVC) September 8, 2019Paper Accepted at IEEE ICCE-Berlin 2019: Light Field Image Compression Using Versatile Video Coding (VVC)
    Our research paper on light field image compression using the upcoming video coding standard VVC (Versatile Video Coding) has been accepted for presentation at the IEEE International Conference on Consumer Electronics in Berlin, Germany. Light field cameras (or plenoptic cameras) made it possible to not only capture information about the light intensity in a scene, but ...
  • Paper presented at SPIE optics + photonics 2019 August 14, 2019Paper presented at SPIE optics + photonics 2019
    An overview research paper on multi-view HEVC (MV-HEVC) prediction structures for light field video compression was presented during the 2019 SPIE optics + photonics international conference in San Diego, CA. 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 ...
