This is primarily a question for Oleg, but I'm posting it here because I'm hoping for an answer more quickly than he may be able to provide. It is in regard to one of his pages on the J wiki:
http://www.jsoftware.com/jwiki/OlegKobchenko/Background%20Removal The line I'm looking at is this one: S=: |: _10(>./)\|: _10(>./)\ M What I'm doubting is the correctness of M, the root value of this noun phrase. R, created before this sentence, is only used for display. (Shape, viewwh, and plot are all used to examine R, after which it's ignored.) Perhaps the point of computing R is to see the features via plot. If so, I'd love to see that plot included on this page. In that case, though, I'm not sure why there would be a need to restore size, which is accomplished in defining Z. Even if R is the correct value for the far right of the sentence that defines M, I'm confused. The image is reduced to 1r5 its previous length along each axis, while Z enlarges it by doubling the length of both axes. This doesn't make sense to me, and I don't see another reduction to be undone. Tomorrow I'll be discussing Oleg's Background Removal during my presentation at PrizCon, so replies that occur today have a chance of helping in ways that later ones won't. (However, I anticipate presenting this example in future talks, also.)
