In equation 19 could anyone tell me what Rbeta and Rgamma represent? My understanding is that Ralpha can be any one of the three rows of R (alpha = 1,2,3).
If Walpha represents any one of three new vectors then what does Wbeta and Wgamma represent? - (see equations 25-27)

I'm looking for this paper too. Can somebody tell me how to get it please? Thanks a lot.

I think the notation in the paper is a bit spotty at some places. e.g. equation 10 simplification. I would be interested in knowing what is responsible for it, my misunderstanding of the algebra, or a typo error for real

I found the paper very short and dense. As it was stated in previous responses i found the paper somewhat dry also.

I think that the eight-point algorithm described in the paper was novel idea at its time. I wonder what other approaches emerged since than and how the performance of these new approaches compare to the one described in this paper. Mentioning the scenarios in which the algorithm fails was a useful one, however i did not gain enough insight into the details of the algorithms to be able to explain them. It would be nice to hear a presentation where one of these scenarios will be analyzed.

I think it's great that he has an algorithm to do this, but i still don't have much insight into why this works, and what's violated in the cases where it fails. Is there some more intuitive way to look at it?

The problem this paper discusses is interesting, however I find the actual article itself somewhat dry. Some of the notation was a bit difficult to follow. Generally speaking, this paper is perfect if you are trying to implement a system for 3-D reconstruction, given a pair of images. However, I don't see the paper as being helpful for much more than this (to the author's benefit, I don't think this was the goal of the paper). As such, I found the paper very mechanical and not particulalry intrigueing. I am, however, interested to hear the presentation, which I'm sure will cover this topic more generally :)
