 -Message from TC-10 chair

 Dear TC10 members and friends,

 Welcome to issue #65 of TC10 News.

 From the last Newsletter of February, 4 months are gone very fastly.

 During last 4 months, my server has hacked and we lost the lots of data.

 Finally we restore the row data for the Newsletter again. I am really


 about to stop the services of Newsletter for some moment. From now,

 The homepage migration is partially done. So you may connect to

 www.iapr-tc10.or.kr  as your favorite site. The membership database is

 not working in this moment will renewed soon. This homepage is similar

 structure of Atul's, but we create the BBS(Bulletin Board System), so if you have

any idea and questions, you may write your opinion freely and may discuss with

other members.

 In this year we have a 2 big events: GREC2001 and ICDAR2001.

 GREC2001(4th workshop) which is hosted by TC-10  will be held at Kingston

 (Ontario, Canada), September 7-8, 2001. The homepage is http://www.cs.queensu.ca/grec2001.

 ICDAR2001(6th conference) which is hosted by TC-10 and TC-11will be held  

at Seattle (Washington, USA), September 10-13, 2001. ICDAR Home Page is  http://isl.ee.washington.edu/IAPR/ICDAR01.
