Cool-chic video: Learned video coding with 800 parameters

1 code implementation5 Feb 2024 Thomas Leguay, Théo Ladune, Pierrick Philippe, Olivier Déforges

We propose a lightweight learned video codec with 900 multiplications per decoded pixel and 800 parameters overall.

Efficient Predictive Coding of Intra Prediction Modes

no code implementations9 Oct 2023 Kevin Reuzé, Wassim Hamidouche, Pierrick Philippe, Olivier Déforges

The high efficiency video coding (HEVC) standard and the joint exploration model (JEM) codec incorporate 35 and 67 intra prediction modes (IPMs) respectively, which are essential for efficient compression of Intra coded blocks.

Revisiting Model's Uncertainty and Confidences for Adversarial Example Detection

1 code implementation9 Mar 2021 Ahmed Aldahdooh, Wassim Hamidouche, Olivier Déforges

Moreover, the state-of-the-art detection techniques have been designed for specific attacks or broken by others, need knowledge about the attacks, are not consistent, increase model parameters overhead, are time-consuming, or have latency in inference time.

Perceptual Evaluation of Adversarial Attacks for CNN-based Image Classification

1 code implementation1 Jun 2019 Sid Ahmed Fezza, Yassine Bakhti, Wassim Hamidouche, Olivier Déforges

However, all the works proposed in the literature for generating adversarial examples have used the $L_{p}$ norms ($L_{0}$, $L_{2}$ and $L_{\infty}$) as distance metrics to quantify the similarity between the original image and the adversarial example.
