RESEARCH OUTLINE3D Color Barcode

We developed 3D Color Barcode in 2007.Large capacity data can be saved compared with the existing bar code.

3D Color Barcode has high encryption capability.

We considered 3D Color Barcode as print media.

Technoproject, Ltd. found out the charm as electronic media to 3D Color Barcode.

Since Technoproject, Ltd. was developing the distance medical service system, he was looking for the electronic media for communicating medical information.

We are performing the joint research aiming at electronic media use of 3D Color Barcode from 2010.

THE COMPRESSION EFFECT OF THE MEDICAL IMAGE20 serial MRI images

compress

The compressibility comparison with ZIP, lossless JPEG, and the proposing method

3D color barcode based method has achieved compressibility high not less than 14% compared with ZIP.

It has achieved compressibility high not less than 5% compared with lossless JPEG.

Since there are also few computational complexities, this technique is a practical technique.

A FUTURE RESEARCH PROGRAM

1. Use to the community medicine network system which Technoproject, Ltd. develops

2. It aims at spread as secure data transfer and distribution tool.

3. It aims at spread as a security-countermeasures tool of portable terminal data.

4. Improvement in the further compressive performance
