Indian scientist develops new tech for data transfer
Wednesday, June 08, 2005
CHENNAI: A Chennai based young scientist has claimed to have invented a
superior "lossless" compression technology for data transfer and management.
With simple repetition coding, the new technology, Adaptive Binary
Optimization (ABO), will achieve not only "lossless" compression but also
more compression.
"In this ABO technology, we maintain a binary index to store the original
location of the data when we do the rearrangement and coding. At the
decompression stage, we can bring back the original data since we had already
indexed the location," said 25-year-old Arvind Thiagarajan, who is an
engineer in electronics and communication.
With ABO, for which patent applications are pending, large volume of data and
big images can be captured and stored using lower processing power. It can
transmit the data and images from one place to another using lower bandwidth
connectivity, particularly without any "loss" of data.
When Thiagarajan first applied this compression technique on the images from
hospital in Singapore, he could achieve 35 times lossless compression. In
traditional techniques like JPEG, MPEG, the compression was only four or five
times and there were certain levels of loss of data.
Impressed with the technology, an American doctor coined a new expansion for
ABO - A Better Option.
Thiagarajan said, "No one could believe it and even the scientific community
was skeptical. We engaged Ernst & Young technology audit team to do the
testing."
"The compression rates may further be improved as we are working on this
process," said Thiagarajan, who along with Ravi Govindan, an Indian
businessman in Singapore, founded MatrixView Technologies (India) Pvt Ltd, to
develop products for commercial applications.
MatrixView was registered in Australia as a foreign company in May 2004 and
was listed on Australian Stock Exchange on August 5, 2004.
Thigarajan said it would require 60 GB space to digitize the moving frame of
echo data in hospitals. But with 30 times compression by ABO technology, it
can be compressed to 2 GB of data.
"In India, using ABO technology, compressed images from rural clinics can be
sent to, using less bandwidth, specialty hospitals in the city for expert
opinion," said Govindan.
EchoView increased productivity by at least 40 percent and saves significant
costs and time for both doctors and patients, Sri Sathya Sai Institute of
Higher Medical Sciences, which is using the equipment said.
MatrixView's second product for document imaging has useful application in
financial services, insurance, healthcare and government where huge piles of
papers are to be scanned and stored.
"DocuMAT can store this in a centralized depositary in a highly compressed
manner to save a lot of storage costs," Thiagarajan said. The company has
filed 13 patents and it will be filing few more in the near future.
