Online Overexposed Pixels Hallucination in Videos with Adaptive Reference Frame Selection

no code implementations29 Aug 2023 Yazhou Xing, Amrita Mazumdar, Anjul Patney, Chao Liu, Hongxu Yin, Qifeng Chen, Jan Kautz, Iuri Frosio

We present a learning-based system to reduce these artifacts without resorting to complex acquisition mechanisms like alternating exposures or costly processing that are typical of high dynamic range (HDR) imaging.

FOVQA: Blind Foveated Video Quality Assessment

no code implementations24 Jun 2021 Yize Jin, Anjul Patney, Richard Webb, Alan Bovik

Previous blind or No Reference (NR) video quality assessment (VQA) models largely rely on features drawn from natural scene statistics (NSS), but under the assumption that the image statistics are stationary in the spatial domain.

Evaluating Foveated Video Quality Using Entropic Differencing

no code implementations12 Jun 2021 Yize Jin, Anjul Patney, Alan Bovik

To reduce stresses on bandwidth, foveated video compression is regaining popularity, whereby the space-variant spatial resolution of the retina is exploited.

Learning to Compress Videos without Computing Motion

1 code implementation29 Sep 2020 Meixu Chen, Todd Goodall, Anjul Patney, Alan C. Bovik

Our framework exploits the regularities inherent to video motion, which we capture by using displaced frame differences as video representations to train the neural network.

Spoke-Darts for High-Dimensional Blue-Noise Sampling

1 code implementation5 Aug 2014 Scott A. Mitchell, Mohamed S. Ebeida, Muhammad A. Awad, Chonhyon Park, Anjul Patney, Ahmad A. Rushdi, Laura P. Swiler, Dinesh Manocha, Li-Yi Wei

Blue noise sampling has proved useful for many graphics applications, but remains underexplored in high-dimensional spaces due to the difficulty of generating distributions and proving properties about them.
