My guess is that it would be simpler to start fresh. -Tony

Stefan, Can you point me to that code? Thanks. I request all the community members to review my proposal and comment for any possible improvements. Thanks. Regards, Ankit.

Hi. I have just made a pull request with wu's circle generation (one of the "Requested features"). It has nothing to do with the proposed project, but now I can build skimage and understand how to commit my changes. Circle images are attached to this post. вторник, 30 апреля 2013 г., 4:33:48 UTC+4 пользователь Stefan van der Walt написал: > > Hi Fedor > > On Tue, Apr 30, 2013 at 12:54 AM, Fedor Morozov <f-mo...(a)ya.ru<javascript:>> > wrote: > > My name is Fedor Morozov and I am a 2nd year computer science student in > > Moscow State University. > > Thanks for getting in touch! > > > What do you think about such project?

GSoC 2013 Proposal : Implementation of STAR and Binary Feature Detectors and Descriptors
by Ankit Agrawal May 1, 2013

May 1, 2013

Hi everyone, I have made the first draft of my proposal<https://github.com/scikit-image/scikit-image/wiki/GSoC-2013-Ankit-Agrawal-I…>and uploaded it on our github wiki. I would like all the mentors and community members to review it and comment for any possible improvements and suggestions. I have some of personal comments on it : 1] I feel that implementing all the four features is slightly ambitious and implementing three of them would be the best. After skimming through papers, this is the order of difficulty in terms of implementation : BRIEF < STAR < FREAK < BRISK(most difficult) 2] As mentioned in the BRISK paper<http://www.robots.ox.ac.uk/~vgg/rg/papers/brisk.pdf>, BRISK detector makes use of FAST detector<http://web.eecs.umich.edu/~silvio/teaching/EECS598_2010/slides/11_16_Hao.pdf>in the process. If it comes down to implementing 3 instead of 4 features, it would be best that I implement FAST as the 4th feature instead of BRISK, which would relax the timeline a bit and will give me more time for testing and optimizing. I suggest all members to review and share their opinions on it as soon as possible so that I can make the changes and upload it on gsoc-melange site. Thank you for your time. Regards, Ankit Agrawal, Communication and Signal Processing, IIT Bombay.
