Low-Latency Neural Stereo Streaming

no code implementations26 Mar 2024 Qiqi Hou, Farzad Farhadzadeh, Amir Said, Guillaume Sautiere, Hoang Le

The rise of new video modalities like virtual reality or autonomous driving has increased the demand for efficient multi-view video compression methods, both in terms of rate-distortion (R-D) performance and in terms of delay and runtime.

Bitstream Organization for Parallel Entropy Coding on Neural Network-based Video Codecs

no code implementations1 Dec 2023 Amir Said, Hoang Le, Farzad Farhadzadeh

Video compression systems must support increasing bandwidth and data throughput at low cost and power, and can be limited by entropy coding bottlenecks.

Optimized learned entropy coding parameters for practical neural-based image and video compression

no code implementations20 Jan 2023 Amir Said, Reza Pourreza, Hoang Le

Neural-based image and video codecs are significantly more power-efficient when weights and activations are quantized to low-precision integers.

Quantization Video Compression

Boosting neural video codecs by exploiting hierarchical redundancy

no code implementations8 Aug 2022 Reza Pourreza, Hoang Le, Amir Said, Guillaume Sautiere, Auke Wiggers

In video compression, coding efficiency is improved by reusing pixels from previously decoded frames via motion and residual compensation.

MobileCodec: Neural Inter-frame Video Compression on Mobile Devices

no code implementations18 Jul 2022 Hoang Le, Liang Zhang, Amir Said, Guillaume Sautiere, Yang Yang, Pranav Shrestha, Fei Yin, Reza Pourreza, Auke Wiggers

Realizing the potential of neural video codecs on mobile devices is a big technological challenge due to the computational complexity of deep networks and the power-constrained mobile hardware.

Truth Serum: Poisoning Machine Learning Models to Reveal Their Secrets

no code implementations31 Mar 2022 Florian Tramèr, Reza Shokri, Ayrton San Joaquin, Hoang Le, Matthew Jagielski, Sanghyun Hong, Nicholas Carlini

We show that an adversary who can poison a training dataset can cause models trained on this dataset to leak significant private details of training points belonging to other parties.

Deep Homography Estimation for Dynamic Scenes

1 code implementation CVPR 2020 Hoang Le, Feng Liu, Shu Zhang, Aseem Agarwala

We then develop a multi-scale neural network and show that when properly trained using our new dataset, this neural network can already handle dynamic scenes to some extent.

Interactive Boundary Prediction for Object Selection

no code implementations ECCV 2018 Hoang Le, Long Mai, Brian Price, Scott Cohen, Hailin Jin, Feng Liu

Instead of relying on pre-defined low-level image features, our method adaptively predicts object boundaries according to image content and user interactions.

Scaling Properties of Human Brain Functional Networks

no code implementations2 Feb 2017 Riccardo Zucca, Xerxes D. Arsiwalla, Hoang Le, Mikail Rubinov, Paul Verschure

We test for the power-law, exponential, log-normal and generalized Pareto distributions.
