Dear Sirs,

I am a computer science student at the Faculty of Sciences, University of Porto, Portugal, and I am writing an essay on the topic of "Digital Image Processing". More specifically, I'm conducting an enquiry on open-source software for digital image processing purposes. My idea is to collect, analyse and test the most popular applications, including their functionalities, user-friendliness, plug-in development facilities, etc. I have short-listed your software for my survey and would like to know your availability to contribute to this project. More specifically, I would like to know your opinion about your software (ease of use, functionalities, flexibility, etc) and I was wondering if I could send you a small questionaire that will not take more than 15 minutes to answer. I will, of course, send you the final copy of my survey (including tests and conclusions), if you are kind enough to contribute in this project.

Thank you for your attention. Please contact me or my supervisor (Dr. Miguel Coimbra - mcoimbra@fc.up.pt - www.ieeta.pt/sias/member/mcoimbra.php), if you need any information on this.

Best regards, Nelson Gomes
