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.

RILOD: Near Real-Time Incremental Learning for Object Detection at the Edge

no code implementations26 Mar 2019 Dawei Li, Serafettin Tasci, Shalini Ghosh, Jingwen Zhu, Junting Zhang, Larry Heck

The key component of RILOD is a novel incremental learning algorithm that trains end-to-end for one-stage deep object detection models only using training data of new object classes.

Regularize, Expand and Compress: Multi-task based Lifelong Learning via NonExpansive AutoML

no code implementations20 Mar 2019 Jie Zhang, Junting Zhang, Shalini Ghosh, Dawei Li, Jingwen Zhu, Heming Zhang, Yalin Wang

Lifelong learning, the problem of continual learning where tasks arrive in sequence, has been lately attracting more attention in the computer vision community.

Talking Face Generation by Conditional Recurrent Adversarial Network

1 code implementation13 Apr 2018 Yang Song, Jingwen Zhu, Dawei Li, Xiaolong Wang, Hairong Qi

Given an arbitrary face image and an arbitrary speech clip, the proposed work attempts to generating the talking face video with accurate lip synchronization while maintaining smooth transition of both lip and facial movement over the entire video clip.
