Lightweight Image Codec via Multi-Grid Multi-Block-Size Vector Quantization (MGBVQ)
Yifan Wang, Zhanxuan Mei, Ioannis Katsavounidis +1
A multi-grid multi-block-size vector quantization (MGBVQ) method is proposed for image coding in this work. The fundamental idea of image coding is to remove correlations among pix…
A Machine Learning Approach to Optimal Inverse Discrete Cosine Transform (IDCT) Design
Yifan Wang, Zhanxuan Mei, Chia-Yang Tsai +2
The design of the optimal inverse discrete cosine transform (IDCT) to compensate the quantization error is proposed for effective lossy image compression in this work. The forward…
A Hitchhiker's Guide to Structural Similarity
Abhinau K. Venkataramanan, Chengyang Wu, Alan C. Bovik +2
The Structural Similarity (SSIM) Index is a very widely used image/video quality model that continues to play an important role in the perceptual evaluation of compression algorith…
Towards Perceptually Optimized End-to-end Adaptive Video Streaming
Christos G. Bampis, Zhi Li, Ioannis Katsavounidis +3
Measuring Quality of Experience (QoE) and integrating these measurements into video streaming algorithms is a multi-faceted problem that fundamentally requires the design of compre…
A user model for JND-based video quality assessment: theory and applications
Haiqiang Wang, Ioannis Katsavounidis, Xinfeng Zhang +2
The video quality assessment (VQA) technology has attracted a lot of attention in recent years due to an increasing demand of video streaming services. Existing VQA methods are des…
Prediction of Satisfied User Ratio for Compressed Video
Haiqiang Wang, Ioannis Katsavounidis, Qin Huang +2
A large-scale video quality dataset called the VideoSet has been constructed recently to measure human subjective experience of H.264 coded video in terms of the just-noticeable-di…
