AI总结:

针对压缩图像质量评估的泛化难题,提出基于stacking的融合方法,结合语义与低层信息、聚合全参考和无参考模型结果,在clic2024基准上达79.6%准确率。

摘要:

众所周知,图像质量评估没有通用指标,在这种情况下,针对特定失真的指标会更可靠。图像压缩带来的伪影可视为多种失真的组合,这种组合会随图像内容的不同而变化,因此泛化性是压缩图像质量评估的主要挑战。本研究采用stacking(堆叠集成)方法来提供可靠的评估方案,所提出的图像质量评估(IQA)方法同时利用语义信息和低层信息来模拟人类视觉系统的感知。此外,该方法还融合了全参考(FR)和无参考(NR)模型的结果,以改进所提出的压缩图像质量评估全参考方法。在clic2024感知图像挑战赛的质量基准测试中,该方法准确率达到79.6%,证明了这种基于融合的方法的有效性。

英文摘要:

It is well-known that there is no universal metric for image quality evaluation. In this case, distortion-specific metrics can be more reliable. The artifact imposed by image compression can be considered as a combination of various distortions. Depending on the image context, this combination can be different. As a result, Generalization can be regarded as the major challenge in compressed image quality assessment. In this approach, stacking is employed to provide a reliable method. Both semantic and low-level information are employed in the presented IQA to predict the human visual system. Moreover, the results of the Full-Reference (FR) and No-Reference (NR) models are aggregated to improve the proposed Full-Reference method for compressed image quality evaluation. The accuracy of the quality benchmark of the clic2024 perceptual image challenge was achieved 79.6\%, which illustrates the effectiveness of the proposed fusion-based approach.
