Large-scale pre-trained vision models (PVMs) have shown great potential for adaptability across various downstream vision tasks. However, with state-of-the-art PVMs growing to billions or even trillions of parameters, the standard full fine-tuning paradigm is becoming unsustainable due to high computational and storage demands. In response, researchers are exploring parameter-efficient fine-tuning (PEFT), which seeks to exceed the performance of full fine-tuning with minimal parameter modifications. This survey provides a comprehensive overview and future directions for visual PEFT, offering a systematic review of the latest advancements. First, we provide a formal definition of PEFT and discuss model pre-training methods. We then categorize existing methods into three categories: addition-based, partial-based, and unified-based. Finally, we introduce the commonly used datasets and applications and suggest potential future research challenges.

规模化预训练视觉模型（PVMs）在各种下游视觉任务中表现出很大的适应性。然而，随着最先进的PVMs达到数十亿甚至数万亿参数，传统的完全微调范式变得难以持续，因为其需要巨大的计算和存储需求。为了应对这一挑战，研究人员正在探索参数高效的微调（PEFT），旨在通过最小的参数修改超越完全微调的性能。本调查提供了对视觉PEFT的综合概述和未来方向，对最新的进展进行了系统回顾。首先，我们提供了PEFT的正式定义，并讨论了模型预训练方法。然后，我们将现有方法分为三类：基于添加的、基于部分的和基于统一的。最后，我们介绍了常用的数据集和应用，并提出了未来研究的潜在挑战。所有相关资源可以在该链接中找到。
