Image Duplication and Figure Reuse Detection
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.
Flags identical and altered versions of images, including cropped, rotated, or mirrored figures.
Imagetwin is built for publishers, institutions, and researchers to support high-quality screening.
Detection is based on figures commonly used in publications, such as microscopy, histology, and western blots.
Image Duplication Detection Tool
Reusing figures across multiple submissions or within the same paper, without transparency or attribution, can mislead readers and reviewers. Imagetwin identifies reused images 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.

How Imagetwin Detects Image Duplication
1. Paper or Image Submission
User uploads entire manuscripts, files or individual images to our secure platform for analysis.
2. AI-Powered Analysis
The software checks for duplication using pattern recognition and deep learning, even if the image has been altered.
3. Confidence Score & Reporting
Receive a report highlighting detected issues. Each flagged case includes similarity overlays and a confidence score.
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 100 million indexed figures. See Image Plagiarism.
Cropped or Resized Reuse
Figures that have been cropped, zoomed in, or resized to look visually distinct.
