You can probably use Deep Learning to learn a better regional point descriptor these days.<br /><br />A great summary can be found in the 2004 Frome et al. paper titled Recognizing Objects in Range Data Using Regional Point Descriptors: <a href="http://www.cs.jhu.edu/~misha/Papers/Frome04.pdf" rel="nofollow">http://www.cs.jhu.edu/~misha/Papers/Frome04.pdf</a>Tomasz Malisiewiczhttps://www.blogger.com/profile/17507234774392358321noreply@blogger.comtag:blogger.com,1999:blog-15418143.post-2685035788716711662016-05-03T09:25:33.017-05:002016-05-03T09:25:33.017-05:00Dear Tomasz,

I am able to generate spin images based on normals(generated using PCA method). However, I am facing problem in matching the model spin image with scene spin image. Can you please let me know how to match spin images.

There was also a PAMI submission in 1998 on the topic, and some other papers came out in 1999. So it really depends on how you date ideas. For me a PhD dissertation is legit enough to count it as the official idea start-time. But he was probably working on these ideas as far back as 1995 or 1994.<br /><br />Tomasz Malisiewiczhttps://www.blogger.com/profile/17507234774392358321noreply@blogger.comtag:blogger.com,1999:blog-15418143.post-48501564800135084752013-11-03T15:03:44.527-05:002013-11-03T15:03:44.527-05:00I think a year of spin-image appearance is 1999, n...I think a year of spin-image appearance is 1999, not 1997.

My research as an undergraduate student was on Range Data Registration, and I used spin images in my research back then.<br /><br />I had written my own code back then, and I suspect a Matlab implementation of spin-images is fairly straightforward if you have several years of hacking experience. The tricky bit is the normal estimation and scale estimation for descriptor. There might also be some issues with non-uniform sampling of points. Check out some of Daniel Huber's papers if you want to learn more about spin images used for 3D vision tasks. Huber also worked with Martial Hebert (briefly after A.E.Johnson, the "spin images were my thesis" guy, graduated from CMU).<br /><br /><br /> If I find any spin-image implementation (especially Matlab), I'll post an update on my blog.Tomasz Malisiewiczhttps://www.blogger.com/profile/17507234774392358321noreply@blogger.comtag:blogger.com,1999:blog-15418143.post-70635661370962170432011-11-04T20:25:12.767-05:002011-11-04T20:25:12.767-05:00do you know of any good implementations for spin i...do you know of any good implementations for spin images (on matlab)?Anonymousnoreply@blogger.com
