Hi everyone, I have made the first draft of my proposal<https://github.com/scikit-image/scikit-image/wiki/GSoC-2013-Ankit-Agrawal-Implementation-of-STAR-and-Binary-Feature-Detectors-and-Descriptors>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.
