Get started Contact sales Frequently Asked Questions How long does it take to scan a manuscript or paper with Imagetwin? The processing time depends on the number of images and figures within a manuscript. On average, Imagetwin completes a full scan in 5 to 20 seconds, ensuring a fast and efficient integrity check. How many images are in the Imagetwin database? Imagetwin has indexed over 120 million images from academic literature. This number continues to grow as we regularly update our database with newly published images from open-access papers and partner organizations. Where does Imagetwin source its database images? Our image database is built through partnerships with academic publishers and journals, granting access to indexed publications. Additionally, we integrate open-source publications to expand our detection capabilities. Why should publishers share their publication database with Imagetwin? By allowing Imagetwin to index your publication database, publishers can detect unauthorized image reuse, duplication, and plagiarism across their entire portfolio. This helps maintain research integrity at scale.We prioritize data privacy and security, ensuring that all image indexing and exchanges are protected with industry-standard encryption and security best practices. Why doesn’t Imagetwin detect all image integrity issues? Our current detection accuracy ranges between 80% to 90%, depending on image type and manipulation complexity. Some factors that influence detection include:Image size, quality, and resolutionApplied transformations (cropping, rotation, scaling)Content complexityWhile no detection tool is perfect, we are continuously improving our AI models to enhance accuracy and expand detection capabilities. What is Imagetwin’s detection rate? Measuring detection accuracy in scientific imaging is complex due to the lack of standardized benchmarks. However, based on internal evaluations using flagged integrity issues from PubPeer, Imagetwin achieves a detection rate of 80% to 90%, depending on the image type and the nature of the integrity concern. How does Imagetwin evaluate its accuracy? We assess accuracy using previously retracted papers and flagged cases from PubPeer. By testing on real-world examples of manipulations, AI-generated images, and duplicates, we refine our detection capabilities to ensure higher reliability. Are scanned manuscripts stored in Imagetwin’s image database? No. Imagetwin does not store or index scanned manuscripts in its database. All uploaded files remain private, and scanned images are never added to our global dataset.For more details, refer to our data privacy policy data privacy policy.

Imagetwin automatically detects splicing, copy-move forgeries, and subtle image adjustments in scientific figures. Using AI and forensic analysis, it flags manipulated regions, such as cloned or resampled areas and splicing seams in western blots.Built-in tools allow users to auto-align transformed images, highlight duplicated keypoints, adjust brightness and contrast, and reveal hidden edits through background visualization. What happens to my images after scanning with Imagetwin? All uploaded images are automatically deleted once processing is complete. However, you can optionally save your scan results in your account for 90 days before they are permanently removed. Can Imagetwin be used for non-scientific images? While optimized for scientific imaging, it can detect manipulation in most structured images, but is not designed for creative or artistic analysis. How does Imagetwin handle rotated, flipped, or scaled duplicates? Imagetwin normalizes transformed images, ensuring accurate comparisons even when figures have been rotated, flipped, or resized. How does Imagetwin highlight duplicated regions? The software automatically detects and marks identical keypoints in flagged images, helping users verify potential manipulation. Can Imagetwin enhance image visibility for better detection? Yes, Imagetwin adjusts brightness and contrast to reveal subtle integrity issues that may not be visible in the original image. --- Skip to content Image Duplication Detection Software Scientific image duplication or figure reuse can compromise transparency and misrepresent results. Imagetwin helps identify reused, cropped, rotated, or mirrored figures both within and across research papers. Get started Accurate Duplication Detection Flags identical and altered versions of images, including cropped, rotated, or mirrored figures. Designed for the Scientific Community Imagetwin is built for publishers, institutions, and researchers to support high-quality screening. Trained on Real Research Images Detection is based on figures commonly used in publications, such as microscopy, histology, and western blots. Image Duplication Detection Software Reusing figures across multiple submissions or within the same paper, without transparency or attribution, can mislead readers and reviewers. Imagetwin identifies self-plagiarism in research even when they are cropped, rotated, or slightly altered.The tool is updated regularly to improve detection accuracy and can help screen preprints, accepted papers, or archived content for self-plagiarism concerns.More details are available in our blog. How Imagetwin Detects Image Duplication 1. Paper or Image SubmissionUser uploads entire manuscripts, files or individual images to our secure platform for analysis. 2. AI-Powered AnalysisThe software checks for duplication using pattern recognition and deep learning, even if the image has been altered. 3. Confidence Score & ReportingReceive a report highlighting detected issues. Each flagged case includes similarity overlays and a confidence score. Get started What Image Duplications can Imagetwin detect? Imagetwin identifies a broad range of visual duplication types, including subtle and transformed reuse that often escapes manual review. These include: Exact Duplications Identical images reused in multiple places, either within the same manuscript or across separate submissions. These may appear in different contexts or figure labels. Contrast and Brightness Adjustments Subtle changes in brightness, exposure, or contrast can be used to make reused figures appear unique. The system detects visual similarity even after tonal manipulation. Partial or Cloned Regions Small regions copied from one part of an image into another. These may include gel bands, microscopy sections, or background textures to fill space or fabricate results. Rotated or Flipped Images Images that have been rotated or mirrored to obscure reuse. This includes 90, 180, or 270 degree rotation as well as horizontal or vertical flipping. Plagiarised Figures from Published Articles Images that appear across separate publications without proper attribution. These are detected through comparison with over 120 million indexed figures. See Image Plagiarism. Cropped or Resized Reuse Figures that have been cropped, zoomed in, or resized to look visually distinct. Why Choose Imagetwin?
