The mechanism that the software "LP-exam" that perceives image fabrication detects illegality is like this

A venture company founded in March 2014 centered on the University of Tokyo life science researcher "LPixel (El Pixel)"Is software that detects" unnatural places such as cutting and pasting and machining "by applying state-of-the-art image processing technology"LP-exam"Was developed. Currently, online versions are released on the site for free, and movies are also released to explain how STAP papers published in Nature are detected as examples.

The purpose of development of LP-exam is as follows.

An indication that there is unauthorized processing and unnatural spots in the images included in the STAP cell paper published in the English science magazine "Nature" is not only the life science world, but also as a social problem surrounding papers fabrication a great deal of attention I am gathering. In LPixel, the life science expert team himself developed the "image fraud detection software LP-exam" by applying advanced image processing technology, making full use of the know-how of life science research. Combine multiple methods and output 8 analysis results from the original image to support fraud detection.

The usage of LP-exam using the image of the STAP cell paper of Riken Rocco Kozo · Ms. Haruko Komuko posted in English scientific journal Nature can be confirmed in the following movie.

Click STEP 3 "Start analysis".


After waiting for a while, 9 images with image processing appeared.


The image is processed to a dark background image, a bright / dark inverted image, a color map image, a multi-step contrast emphasized image, and a high pass processed image.

Click "Start analysis".


The image has been processed.


"The trace of image insertion can be seen in the lane at the right end of electrophoresis (blue frame)".


The processed image can be saved.


Scaling out experimental results of scientific papers is quite handy. By LP-exam, it is likely that an unforgivable check will be placed on suspicious experimental results.
