Artificial Intelligence Section

知能工学研究室

The Artificial Intelligence Section is engaged in research and development of technologies for forensic examination using image engineering and information engineering. In particular, our research domains cover the following wide scope of topics:

Forensic image and video analysis
Big data analytics with criminal databases
Fundamental techniques related with artificial intelligence including deep learning

Within the areas described above, we also deliver expert evidence as expert technical witnesses.

R & D on Forensic Image and Video Analyses

Our research themes related with forensic image and video analyses are:

Estimation of physical quantity such as human height and vehicle velocity
Camera identification using CCD fingerprint method
Image enhancement
Person identification using gait analysis
Character recognition for captured objects in images (eg. license-plate numbers and characters printed on clothes)
Detection of tampered images

Image analysis software
