This article may be too technical for most readers to understand.(September 2010) |
There is very little explanation of what is going on before diving in to higher level math. There should be more explanation of what is happening.â WAvegetarian⢠(talk) 06:21, 27 January 2007 (UTC)
Also it is pretty misleading to do it in 3D - the only case where those equations really apply is if you are tracking something in a CT or MRI scanner. Usually optical flow is 2D. 155.198.65.29 ( talk) 09:46, 4 April 2008 (UTC)
The original paper never uses the words "optical flow". This article presents the method in terms of optical flow, which is in fact a separate topic with its own article. Suggest forming the discussion around the concept of disparity and correspondence (as in the original applications to image registration and stereo depth estimation) and moving optical flow to another section. 09:53, 25 June 2008
"As a pixel at location (x, y,z, t) with intensity I(x, y,z, t)" is completely wrong. Pixels do not have 3 Dimensions... should be (x,y,t) in this case. Or change to Voxel. In any case, it is a bit retarded to describe this problem in 3D. Would make it a tad bit easier to understand if you restrict the problem to x,y and t. ~Skela , 31July2008
As you can read here: http://www.ces.clemson.edu/~stb/klt/ this method has been presented as: An Iterative Image Registration Technique with an Application to Stereo Vision. So why does the article say that it is a non-iterative method? And the reference implementation offered in the same page works with raster images, so why does the articles try to explain it in terms of voxel?. Also, I understand that an important step in the algorithm involves the Newton method. So why the article talks about least squares? Whoever wrote this supposed explanation was on crack. -- Femmina ( talk) 16:18, 17 March 2009 (UTC)
I've removed the Detailed treatment section because it's misleading, contradicts itself, the reference material and contains original research and dubious claims. Various problems with that section have been noticed by users both in this talk page and on Dawoodmajoka's talk page which seems to be the only author. -- Femmina ( talk) 18:14, 18 March 2009 (UTC)
I have reverted your changes. This is no way of dealing with diffeence of opinion. You have not presented any alternative, neither have you proposed any improvements. Just to delete something because it does not confrms to your idea of something is not to be made a habit. The only objection to the article so far was about 3d+t implementation vs. 2d+t implementation. At the request and insistence of some readers I have changed to 2d+t. There was no other objection to it. What "dubious claims". If you do not know the field then please refrain from writing unsubstantiated statements! If you have any constructive criticism on the now amendend article, please do share it. Dawoodmajoka ( talk) 19:46, 18 March 2009 (UTC)
Large parts of the confusion in the comments here seem to be due to KLT linking here, which is misleading, as it is not the same. The Kanade-Lucas-Tomasi (KLT) method is a method for tracking image features (see link and link). The foundation of KLT feature tracking and the Lucas-Kanade method for optical flow was laid by the same paper by Lucas and Kanade. Note, however, that this original paper is neither about optical flow nor feature tracking but about registering two images. link
Imho, KLT feature tracking deserves its own article! I don't dare writing it myself at the moment, though. -- Sbstn ( talk) 17:25, 25 August 2009 (UTC)

The IPA reading doesn't seem right to me. I think it should end in e instead of ÉŞ. Japanese phonology also says that the Japanese e is an mid front unrounded vowel, and not a Near-close near-front unrounded vowel, which seem like an American mispronounciation. If no citation is added, I will remove the pronounciation in a week. -- 129.247.247.240 ( talk) 01:02, 26 March 2018 (UTC)
