3-DIMENSIONAL GALLERY

The 3-D Gallery is meant to demonstrate two components of our research efforts, dating back to 1993. The effort and strategy was to extend through innovation and combine two areas of research: (1) 3-D Data Acquisition and (2) Pattern Recognition. We have associated this effort with the name of “5-D Studio”. The first 3 dimensions are spatial, the 4^th is time or motion and the 5^th dimension represents going beyond 4-D. We used the term studio instead of laboratory to indicate the service component of our research. In this case, our research includes the study of the data acquisition process as well as the scanning device.

FACIAL SCANS

MICROSCOPIC SCANS

You will need to download GL3Dview.exe to view “mat5” files. The new version uses a menu with File Open to open the mat5 files but is very similar to the older version which has a tutorial video at soft3d.

Bullet Scan (zipped to 24 megabyte single file mat5 F file format) and single patch of bullet Video (66 Megabytes)

3-D JAVA APPLETS, PHOTOS AND VIDEOS

We have experimented with JAVA applets below. We have found that they may be difficult to operate on some computers so we will be trying new ways of exchanging the data in the future.

To view the 3-D gallery you must have some JAVA software installed. It is definitely worth it and only needs to be done once. Although it may take a while we hope to develop downloadable installations so users can create their own galleries. Developers: Charles Casey and Veerganesh Yalla.

HOW TO SETUP 3-D JAVA APPLET VIEWER FOR YOUR BROWSER

• Mouse Controls
  - Left click and drag to ROTATE
  - Center click and drag, or use mouse wheel, to ZOOM
  - Right click and drag to TRANSLATE

PATTERN RECOGNITION

A second component to the 5-D Studio project is the combination of pattern recognition with 3-D data acquisition.

MANY 2-D VIEWS FROM ONE 3-D SCAN

The concept of “Many 2D from One 3D” is to acquire a single 3-D scan of a face. From that single scan, any pose, scale, shading or resolution can be obtained to best match any security 2-D video sequence. The matching is then done at the security camera resolution so that the original security video is not enhanced or altered but instead the single 3-D scan is rendered scientifically to test the match.
