SG-JND: Semantic-Guided Just Noticeable Distortion Predictor For Image Compression

no code implementations8 Aug 2024 Linhan Cao, Wei Sun, Xiongkuo Min, Jun Jia, ZiCheng Zhang, Zijian Chen, Yucheng Zhu, Lizhou Liu, Qiubo Chen, Jing Chen, Guangtao Zhai

Just noticeable distortion (JND), representing the threshold of distortion in an image that is minimally perceptible to the human visual system (HVS), is crucial for image compression algorithms to achieve a trade-off between transmission bit rate and image quality.

Enhancing Blind Video Quality Assessment with Rich Quality-aware Features

1 code implementation14 May 2024 Wei Sun, HaoNing Wu, ZiCheng Zhang, Jun Jia, Zhichao Zhang, Linhan Cao, Qiubo Chen, Xiongkuo Min, Weisi Lin, Guangtao Zhai

Motivated by previous researches that leverage pre-trained features extracted from various computer vision models as the feature representation for BVQA, we further explore rich quality-aware features from pre-trained blind image quality assessment (BIQA) and BVQA models as auxiliary features to help the BVQA model to handle complex distortions and diverse content of social media videos.
