2-2. Multi-perspective search (overview) Acc

ident

Huge volume video data

Surveillance camera Video recorder

Video content analysis

Clues from witnesses

He was bringing a green backpack.

I saw a suspicious guy wearing blue parka.

Finding suspicious

person

High-speed Image search

Search the person having "a green backpack" and wearing "blue parka."

Even unregistered persons can be searched by appearance from recorded video

Color of items, face, trail of movement, etc.

Suspect-tracking technology based on clothing, hand luggage and route taken


Detection of faces, clothes, hand luggage and route from video data

Registration of image features extracted from above objects

High-speed search of specific person （36M images/seconds）

Surveillance camera

Smartphone video

Video recorder

2-3. Finger-vein authentication (overview)

Emerging threats of terrorism to large events Trade-off between certainty of inspection of attendees and throughput of

gate entrance.

Stadiums

・ ID inspection ・ Checking tickets etc.

Rigorous inspection leads to severe congestion

Stations

Entrance

Providing innovative authentication system – high speed with high accuracy


2-3. Finger vein authentication (technology)

Walk-through

Pattern

• Stop and put a finger

into the equipment

Problems Technology

Congestion

• Walk-through finger vein authentication

Movement

3D image

IR image

LED projection

Finger detection

Estimating posture from 3D image

Capturing images of

moving fingers

Touch & Go

Realizing walk-through authentication, same rate as automatic ticket gate


2-3. Finger vein authentication (demo video)

Greater security and reduced congestion at admission gates where crowds form

Authenticated by passing fingers over the reader (70 person/min)

Finger vein authentication technology for smooth and accurate walkthrough-style personal verification
