AI总结:

本文系统分析并验证了 BoVW、Yottixel、SISH 和 RetCCL 等组织病理学图像搜索引擎,基于超 20 万图像块评估其准确性与效率,指出当前方法难以兼顾两者,亟需进一步研究。

摘要:

在组织学和组织病理学图像档案中搜索相似图像是一项关键任务,可在患者匹配中发挥作用,其用途涵盖分诊、诊断、预后和预测等多个方面。全切片图像(WSIs)是安装在载玻片上的组织标本的高精细数字表示。将 WSI 与 WSI 进行匹配可作为患者匹配的关键方法。本文报告了对四种搜索方法的广泛分析与验证,包括视觉词袋(BoVW)、Yottixel、SISH、RetCCL 及其若干潜在变体。我们分析了它们的算法和结构,并评估了其性能。在此评估中,我们使用了四个内部数据集(1269 名患者)和三个公开数据集(1207 名患者),共计超过 200,000 个图像块,来自五个主要部位的 38 个不同类别/亚型。某些搜索引擎(例如 BoVW)表现出显著的效率和速度,但准确率较低。相反,Yottixel 等搜索引擎在效率和速度方面表现良好,并能提供中等准确的结果。近期提出的方法(包括 SISH)表现出效率低下且结果不一致,而 RetCCL 等替代方案在准确性和效率方面均显不足。进一步的研究对于解决组织病理学图像搜索中准确性与最小存储需求的双重问题至关重要。

英文摘要:

Searching for similar images in archives of histology and histopathology images is a crucial task that may aid in patient matching for various purposes, ranging from triaging and diagnosis to prognosis and prediction. Whole slide images (WSIs) are highly detailed digital representations of tissue specimens mounted on glass slides. Matching WSI to WSI can serve as the critical method for patient matching. In this paper, we report extensive analysis and validation of four search methods bag of visual words (BoVW), Yottixel, SISH, RetCCL, and some of their potential variants. We analyze their algorithms and structures and assess their performance. For this evaluation, we utilized four internal datasets ($1269$ patients) and three public datasets ($1207$ patients), totaling more than $200,000$ patches from $38$ different classes/subtypes across five primary sites. Certain search engines, for example, BoVW, exhibit notable efficiency and speed but suffer from low accuracy. Conversely, search engines like Yottixel demonstrate efficiency and speed, providing moderately accurate results. Recent proposals, including SISH, display inefficiency and yield inconsistent outcomes, while alternatives like RetCCL prove inadequate in both accuracy and efficiency. Further research is imperative to address the dual aspects of accuracy and minimal storage requirements in histopathological image search.
