本文提出 UG-ICM,利用 CLIP 的全局到实例监督和条件解码,以单一码流同时支持人类感知与未知机器分析任务。

摘要:

长期以来,图像压缩模型在适应性和泛化能力方面一直面临困难,因为解码后的码流通常只服务于人类或机器需求,无法为未见过的视觉任务保留信息。因此,本文创新性地引入从多模态预训练模型获得的监督,并结合自适应多目标优化,旨在通过单一码流同时支持人类视觉感知与机器视觉,所提出方法称为 Unified and Generalized Image Coding for Machine(UG-ICM)。具体而言,为摆脱压缩模型对下游任务监督的依赖,我们将 Contrastive Language-Image Pre-training(CLIP)模型引入训练约束,以提升泛化能力。研究采用从全局到实例的 CLIP 监督,以帮助获取层次化语义,使模型在依赖不同粒度信息的任务上具有更强的泛化性。此外,为了仅用一个统一码流同时支持人类视觉和机器视觉,我们引入条件解码策略,将人类或机器偏好作为条件,使码流能够针对相应偏好解码为不同版本。因此,所提出的 UG-ICM 完全以自监督方式训练,即不感知任何特定的下游模型和任务。大量实验表明,所提出的 UG-ICM 能够在多种未见过的机器分析任务上取得显著提升,同时提供感知上令人满意的图像。

英文摘要:

The image compression model has long struggled with adaptability and generalization, as the decoded bitstream typically serves only human or machine needs and fails to preserve information for unseen visual tasks. Therefore, this paper innovatively introduces supervision obtained from multimodal pre-training models and incorporates adaptive multi-objective optimization tailored to support both human visual perception and machine vision simultaneously with a single bitstream, denoted as Unified and Generalized Image Coding for Machine (UG-ICM). Specifically, to get rid of the reliance between compression models with downstream task supervision, we introduce Contrastive Language-Image Pre-training (CLIP) models into the training constraint for improved generalization. Global-to-instance-wise CLIP supervision is applied to help obtain hierarchical semantics that make models more generalizable for the tasks relying on the information of different granularity. Furthermore, for supporting both human and machine visions with only a unifying bitstream, we incorporate a conditional decoding strategy that takes as conditions human or machine preferences, enabling the bitstream to be decoded into different versions for corresponding preferences. As such, our proposed UG-ICM is fully trained in a self-supervised manner, i.e., without awareness of any specific downstream models and tasks. The extensive experiments have shown that the proposed UG-ICM is capable of achieving remarkable improvements in various unseen machine analytics tasks, while simultaneously providing perceptually satisfying images.
