摘要:

数据的爆炸式增长导致越来越多的关联文本随图像一起传输。受分布式信源编码的启发,许多工作利用图像边信息来增强图像压缩。然而,现有方法通常没有考虑使用文本作为边信息来增强图像的感知压缩,尽管多模态协同的优势已在研究中得到广泛证明。这引出了以下问题:如何有效地传递文本级语义依赖以帮助图像压缩,而这种依赖仅对解码器可用?在本工作中,我们提出了一种新颖的具有文本引导边信息的深度图像压缩方法,以实现更好的率-感知-失真权衡。具体来说,我们采用CLIP文本编码器和一个有效的语义-空间感知模块来融合文本和图像特征。这是通过预测一个语义掩码来在像素级别引导学习到的文本自适应仿射变换实现的。此外,我们设计了文本条件生成对抗网络来提高重建图像的感知质量。涉及四个数据集和十种图像质量评估指标的广泛实验表明,所提出的方法在率-感知权衡和语义失真方面取得了优越的结果。

英文摘要:

The explosion of data has resulted in more and more associated text being transmitted along with images. Inspired by from distributed source coding, many works utilize image side information to enhance image compression. However, existing methods generally do not consider using text as side information to enhance perceptual compression of images, even though the benefits of multimodal synergy have been widely demonstrated in research. This begs the following question: How can we effectively transfer text-level semantic dependencies to help image compression, which is only available to the decoder? In this work, we propose a novel deep image compression method with text-guided side information to achieve a better rate-perception-distortion tradeoff. Specifically, we employ the CLIP text encoder and an effective Semantic-Spatial Aware block to fuse the text and image features. This is done by predicting a semantic mask to guide the learned text-adaptive affine transformation at the pixel level. Furthermore, we design a text-conditional generative adversarial networks to improve the perceptual quality of reconstructed images. Extensive experiments involving four datasets and ten image quality assessment metrics demonstrate that the proposed approach achieves superior results in terms of rate-perception trade-off and semantic distortion.
