Saliency-Aware Spatio-Temporal Artifact Detection for Compressed Video Quality Assessment

no code implementations3 Jan 2023 Liqun Lin, Yang Zheng, Weiling Chen, Chengdong Lan, Tiesong Zhao

In this paper, we investigate the influence of four spatial PEAs (i. e. blurring, blocking, bleeding, and ringing) and two temporal PEAs (i. e. flickering and floating) on video quality.

LMQFormer: A Laplace-Prior-Guided Mask Query Transformer for Lightweight Snow Removal

1 code implementation10 Oct 2022 Junhong Lin, Nanfeng Jiang, Zhentao Zhang, Weiling Chen, Tiesong Zhao

Secondly, we design a Mask Query Transformer (MQFormer) to remove snow with the coarse mask, where we use two parallel encoders and a hybrid decoder to learn extensive snow features under lightweight requirements.

UIF: An Objective Quality Assessment for Underwater Image Enhancement

no code implementations19 May 2022 Yannan Zheng, Weiling Chen, Rongfu Lin, Tiesong Zhao

In addition, we have also established a large-scale UIE database with subjective scores, namely Underwater Image Enhancement Database (UIED), which is utilized as a benchmark to compare all objective metrics.

Deep Quality Assessment of Compressed Videos: A Subjective and Objective Study

no code implementations7 May 2022 Liqun Lin, Zheng Wang, Jiachen He, Weiling Chen, Yiwen Xu, Tiesong Zhao

In this work, a semi-automatic labeling method is adopted to build a large-scale compressed video quality database, which allows us to label a large number of compressed videos with manageable human workload.

Video Quality Assessment Visual Question Answering (VQA)

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).
