text-extraction

Is there a way to read text(numbers and letters) in an image using C# ? Is this possible and What is the best way to do this ? Thanks! http://code.google.com/p/tesseract-ocr/ has some wrapper to use it in .NET, or, simpler: http://www.codeproject.com/KB/office/modi.aspx but you need to keep an eye to the license since it is a part of the Office suite.

I am a Python beginner and would be very thankful if you could help me with my text extraction problem. I want to extract all text, which lies between two expressions in a textfile (the beginning and end of a letter).

In cases where the "letter_end" has no

I have a comma-delimited list of email addresses with each actual address prepended by the contact's name (from Gmail). Here's an example: Fred Flintstone <fred@flintstone.org>, Wilma Flintstone <wilma@flintstone.org>, Barney Rubble <barney@rubble.org>, Bamm-Bamm Rubble <bammbamm@rubble.org>, converts to: fred@flintstone.org, wilma@flintstone.org, barney@rubble.org, bammbamm@rubble.org, Background info: I am trying to paste the list of contacts into a webex invite, which can only accept email addresses. Remove everything except regex match in Vim is related, but all the email addresses are on

I have these lines repeating FINAL RESULTS NSTEP ENERGY RMS GMAX NAME NUMBER 1000 -4.7910E+01 2.1328E-01 9.4193E-01 C 62 The FINAL RESULTS indicate a average of those values for a set. The output file combines all 1000 sets. I need to grab the number below energy (-4.7910E+01), all 1000 of them in to another file. I need to set FINAL RESULTS as a pattern because other pattern such as NSTEP, ENERGY, RMS.... are repeated in millions. I'll be grateful for any help. Something like this should work for you: awk '/FINAL RESULTS/{for (i=0; i<5; i++) getline; print $2}' <filename> OK, I think I see
