eOMP: Finding Sparser Representation by Recursively Orthonormalizing the Remaining Atoms
Yuanyi Xue, Yao Wang
Greedy algorithms for minimizing L0-norm of sparse decomposition have profound application impact on many signal processing problems. In the sparse coding setup, given the observat…
A two-stage video coding framework with both self-adaptive redundant dictionary and adaptively orthonormalized DCT basis
Yuanyi Xue, Yi Zhou, Yao Wang
In this work, we propose a two-stage video coding framework, as an extension of our previous one-stage framework in [1]. The two-stage frameworks consists two different dictionarie…
A Novel No-reference Video Quality Metric for Evaluating Temporal Jerkiness due to Frame Freezing
Yuanyi Xue, Beril Erkin, Yao Wang
In this work, we propose a novel no-reference (NR) video quality metric that evaluates the impact of frame freezing due to either packet loss or late arrival. Our metric uses a tra…
Q-STAR:A Perceptual Video Quality Model Considering Impact of Spatial, Temporal, and Amplitude Resolutions
Yen-Fu Ou, Yuanyi Xue, Yao Wang
In this paper, we investigate the impact of spatial, temporal and amplitude resolution (STAR) on the perceptual quality of a compressed video. Subjective quality tests were carried…
Perceptual quality comparison between single-layer and scalable videos at the same spatial, temporal and amplitude resolutions
Yuanyi Xue, Yao Wang
In this paper, the perceptual quality difference between scalable and single-layer videos coded at the same spatial, temporal and amplitude resolution (STAR) is investigated throug…
