LLM-based Interaction for Content Generation: A Case Study on the Perception of Employees in an IT department

no code implementations18 Apr 2023 Alexandre Agossah, Frédérique Krupa, Matthieu Perreira Da Silva, Patrick Le Callet

Furthermore, our analyses suggest that the frequency of use of generative tools is likely to be a key factor in understanding how employees perceive these tools in the context of their work.

From Just Noticeable Differences to Image Quality

1 code implementation ACMMM 2022 Ali Ak, Andreas Pastor, Patrick Le Callet

This first JND point provides an intrinsic quantification of the visible distortions within the multimedia content.

On the benefit of parameter-driven approaches for the modeling and the prediction of Satisfied User Ratio for compressed video

no code implementations20 Jun 2022 Jingwen Zhu, Patrick Le Callet, Anne-Flore Perrin, Sriram Sethuraman, Kumar Rahul

However, most of the previous works predict each point in SUR curve by using features both from source video and from compressed videos with assumption that the group-based JND annotations follow Gaussian distribution, which is neither practical nor accurate.

A Framework to Map VMAF with the Probability of Just Noticeable Difference between Video Encoding Recipes

no code implementations16 May 2022 Jingwen Zhu, Suiyi Ling, Yoann Baveye, Patrick Le Callet

To this end, in order to decouple encoding recipes and JND estimation, we propose a novel framework to map the difference of objective Video Quality Assessment (VQA) scores, i. e., VMAF, between two given videos encoded with different encoding recipes from the same content to the probability of having just noticeable difference between them.

Utility-Oriented Underwater Image Quality Assessment Based on Transfer Learning

no code implementations7 May 2022 Weiling Chen, Rongfu Lin, Honggang Liao, Tiesong Zhao, Ke Gu, Patrick Le Callet

Based on this task, we build an Underwater Image Utility Database (UIUD) and a learning-based Underwater Image Utility Measure (UIUM).

Considering user agreement in learning to predict the aesthetic quality

1 code implementation13 Oct 2021 Suiyi Ling, Andreas Pastor, Junle Wang, Patrick Le Callet

In this paper, we thus propose (1) a re-adapted multi-task attention network to predict both the mean opinion score and the standard deviation in an end-to-end manner; (2) a brand-new confidence interval ranking loss that encourages the model to focus on image-pairs that are less certain about the difference of their aesthetic scores.

Seeing by haptic glance: reinforcement learning-based 3D object Recognition

no code implementations15 Feb 2021 Kevin Riou, Suiyi Ling, Guillaume Gallot, Patrick Le Callet

Human is able to conduct 3D recognition by a limited number of haptic contacts between the target object and his/her fingers without seeing the object.

Subjective and Objective Quality Assessment of Mobile Gaming Video

1 code implementation27 Jan 2021 Shaoguo Wen, Suiyi Ling, Junle Wang, Ximing Chen, Lizhi Fang, Yanqing Jing, Patrick Le Callet

Nowadays, with the vigorous expansion and development of gaming video streaming techniques and services, the expectation of users, especially the mobile phone users, for higher quality of experience is also growing swiftly.

Multi-Modal Aesthetic Assessment for MObile Gaming Image

no code implementations27 Jan 2021 Zhenyu Lei, Yejing Xie, Suiyi Ling, Andreas Pastor, Junle Wang, Patrick Le Callet

Our inclination is to seek and learn the correlations between different aesthetic relevant dimensions to further boost the generalization performance in predicting all the aesthetic dimensions.

Strategy for Boosting Pair Comparison and Improving Quality Assessment Accuracy

no code implementations1 Oct 2020 Suiyi Ling, Jing Li, Anne Flore Perrin, Zhi Li, Lukáš Krasula, Patrick Le Callet

The development of rigorous quality assessment model relies on the collection of reliable subjective data, where the perceived quality of visual multimedia is rated by the human observers.

Capturing and Explaining Trajectory Singularities using Composite Signal Neural Networks

no code implementations24 Mar 2020 Hippolyte Dubois, Patrick Le Callet, Michael Hornberger, Hugo J. Spiers, Antoine Coutrot

In this paper we present a novel ANN architecture designed to capture the spatio-temporal patterns characteristic of a set of trajectories, while taking into account the demographics of the navigators.

Binocular Rivalry Oriented Predictive Auto-Encoding Network for Blind Stereoscopic Image Quality Measurement

1 code implementation4 Sep 2019 Jiahua Xu, Wei Zhou, Zhibo Chen, Suiyi Ling, Patrick Le Callet

Stereoscopic image quality measurement (SIQM) has become increasingly important for guiding stereo image processing and commutation systems due to the widespread usage of 3D contents.

How is Gaze Influenced by Image Transformations? Dataset and Model

1 code implementation16 May 2019 Zhaohui Che, Ali Borji, Guangtao Zhai, Xiongkuo Min, Guodong Guo, Patrick Le Callet

Data size is the bottleneck for developing deep saliency models, because collecting eye-movement data is very time consuming and expensive.

Adversarial Attacks against Deep Saliency Models

no code implementations2 Apr 2019 Zhaohui Che, Ali Borji, Guangtao Zhai, Suiyi Ling, Guodong Guo, Patrick Le Callet

The proposed attack only requires a part of the model information, and is able to generate a sparser and more insidious adversarial perturbation, compared to traditional image-space attacks.

GANs-NQM: A Generative Adversarial Networks based No Reference Quality Assessment Metric for RGB-D Synthesized Views

no code implementations28 Mar 2019 Suiyi Ling, Jing Li, Junle Wang, Patrick Le Callet

In this paper, we proposed a no-reference (NR) quality metric for RGB plus image-depth (RGB-D) synthesis images based on Generative Adversarial Networks (GANs), namely GANs-NQM.

Hybrid-MST: A Hybrid Active Sampling Strategy for Pairwise Preference Aggregation

1 code implementation NeurIPS 2018 Jing Li, Rafal K. Mantiuk, Junle Wang, Suiyi Ling, Patrick Le Callet

In this paper we present a hybrid active sampling strategy for pairwise preference aggregation, which aims at recovering the underlying rating of the test candidates from sparse and noisy pairwise labelling.
