hi sir,
i am santosh from india.i doing computer engineering.we completed ,
our final project in java. and our project name is automatic
fingerprint identification

system and this tottaly based on image processing concept. we done
this but our internal guide does not accept this. and suggest some
modification in our

project. i send you to all code, GUI and fingerprint database. you
run this code .
and test our project . the main class file is Finger_Print.java. use
this for testing.
and i write point which is want to my guide, plz advice on that .
# i have in gui four windows. first is user fingerprint which given
from database1 and second given from internal system database2. other
2 are for seeing

what is exactly going on during number of process.but presently both
fingerprint are given user by using file browsing facility. but this
lenghty and time

consuming process when database are big. therefore we want first
fingerprint will given by user using browse facility and second one
given by

automatically second window from database2 and proceed it same like as
before and show the result. but we have problem only that how to give
database

connectivity and automaticaly proceed all fingerprint one by one and
store the result which is matching with that fingerprint. therefore
plz advice me. and

implement your own idea in our project. plz modified our code as you
prefer. and send to me. i wait your advice. bcoz our project
submission will be on 20

th april. plz give me as early as possible. plz all of you reply me
on my email address. THANKING YOU.


my email address: (e-mail address removed)


YOURS FAITHFULLY

SANTOSH





i give code with file name , plz u have copy paste as separate file.
plz download some fingerprint on the internet and test my project.file
save as given name.

..no. But one tip - try to get a clue, before
making further posts to the usenet newsgroups.
Try reading the group for a couple of days, to get
a feel for how it works.

It would have made more sense to zip up your code,
upload to a free site and link to it from your post - that
would at least spare the bandwidth of users of news
clients.

The bandwidth used up by his code was downloadable on my 6mbps
connection as quickly as it takes me to blink. The real issue with
posting that much code in a newsgroup message is the formatting and it
is obvious he spent no time in checking the formatting before posting.
Some of his code has so many indents that it wouldn't look right in a
newsreader no matter what was done.
