Image-Recognition Company Finds New Market in Forensics

In the fast-paced world of the Internet, new technologies are often 
launched with great fanfare only to fizzle out with a whimper. But the 
smart ones are able to adapt and endure. LTU, a French-American tech 
company that won a silver prize in the inaugural Wall Street Journal 
Europe Innovation Awards in 2001, has done exactly that.

A decade ago, four researchers at France's technology-research body 
Institut National de Recherche en Informatique et en Automatique 
developed image-recognition technology that allowed people to use not 
just words, but pictures from the Web or cell phone cameras to search 
for matches.

"Back then image recognition was really seen as rocket science," said 
Alexandre Winter, co-founder and CEO of LTU. "The fact we got the award 
showed it was really a serious technology, and helped us raise our 
second round of venture-capital money."

LTU's recognition systems look for the individual descriptors—such as 
texture, color and shape—that combine to make an image unique. Even if a 
picture has been copied, cropped, compressed or otherwise distorted, 
there is enough data to reveal its source. Once it has been indexed, its 
attributes can be matched to similar images.

For early e-commerce businesses struggling to catalogue their products, 
LTU offered an automated solution. Along with other shopping sites, it 
was a natural fit for iBazar, a European auction Web site later acquired 
by Ebay Inc., which put clickable "find similar" buttons on its photographs.

However, despite its initial success, LTU got caught up in the dot-com 
bust as clients folded or were acquired. The company had to look beyond 
e-commerce, and soon found another growth area: police investigations.

Police forces pursuing child pornographers were collecting millions of 
images of abuse via the Internet, but had no way of finding out where 
they were taken—until LTU's technology allowed rapid cataloguing and 
comparison.

In one well-known Canadian case, a suspected child pornographer had 
destroyed all evidence including CD-ROMs and computer hard drives before 
police arrived. But photographs taken of the suspect's basement and 
living room could be compared with the database of pictures, so 
providing sufficient evidence for the prosecution.

The police also use LTU's software to track down stolen works of art. 
Often the pieces will turn up in auction houses far from where they were 
taken. "This might not save lives, but it does save a lot of money," 
says Dr. Winter.

In 2005, LTU was acquired by Tokyo-listed Japanese software developer 
JASTEC Co., and it has continued to seek new markets. The same software 
used by international police forces to track down stolen paintings is 
available for even relatively low-budget Web sites or on mobile phones.

The technology has also been used in an Apple iPhone application called 
"lookthatup", which allows users to snap a picture of an object then 
instantly find information about it. Behind the application is a search 
engine, much the same as Google, except the queries are based on 
digitized information from pictures rather than words.

"Our positioning now is to provide image recognition to anybody that 
wants it, from small companies using our hosted service to photo 
agencies tracking their copyrighted material, but we still have our 
focus on law enforcement," Dr. Winter said.
