论文摘要
最近,在研究不当行为的论文中发现了伪造的图像。然而,尽管有许多图像伪造的检测方法,但它们都不是为分子生物实验图像而设计的。在本文中,我们提出了一种名为FBI $ _ {gel} $的快速盲目询问方法,以从两种常见的分子实验中获得的图像的完整性,即蛋白质印迹(WB)和聚合酶链反应(PCR)。 FBI $ _ {gel} $基于能够突出局部残留物的优化伪背景,可以揭示可追溯的痕迹,暗示WB/PCR图像上不适当的局部修改。此外,由于优化的伪背景是根据封闭形式的解决方案得出的,因此FBI $ _ {gel} $在计算上是有效的,因此适用于WB/PCR图像完整性的大型查询任务。我们在公众对\ textbf {pubpeer}质疑的几篇论文上应用了FBI $ _ {gel} $,我们的结果表明,这些论文的数字确实包含了可疑的不自然模式。
Recently, falsified images have been found in papers involved in research misconducts. However, although there have been many image forgery detection methods, none of them was designed for molecular-biological experiment images. In this paper, we proposed a fast blind inquiry method, named FBI$_{GEL}$, for integrity of images obtained from two common sorts of molecular experiments, i.e., western blot (WB) and polymerase chain reaction (PCR). Based on an optimized pseudo-background capable of highlighting local residues, FBI$_{GEL}$ can reveal traceable vestiges suggesting inappropriate local modifications on WB/PCR images. Additionally, because the optimized pseudo-background is derived according to a closed-form solution, FBI$_{GEL}$ is computationally efficient and thus suitable for large scale inquiry tasks for WB/PCR image integrity. We applied FBI$_{GEL}$ on several papers questioned by the public on \textbf{PUBPEER}, and our results show that figures of those papers indeed contain doubtful unnatural patterns.
