Re: [Jprogramming] find crop position in image

With getting the thing to compile I'm afraid I cannot help. I once downloaded a linux binary dated July 8, 2005. It reads a .pgm from stdin, writes an ascii keypoint file to stdout, and has very standard dependencies. If all else fails I can send it to you :-) grtz, B On Wed, May 1, 2019 at 3

I use the following adverb, filter=. &> (#~`) (`:6) (>&6) filter 2+i.9 7 8 9 10 ((2&|)*.(>&6)) filter 2+i.9 7 9 It is slightly more complicated than expected because it can also deal with boxed lists, palindrome=. -: |. palindrome filter 'rats live on no evil star' ; 'blessed ar

Thanks, that looks promising. Now to see if I can get the thing to compile, with all of its dependencies... Thanks again, -- Raul On Mon, Apr 29, 2019 at 10:10 PM Ben Gorte wrote: > > Hi Raul, > > I would use Lowe's SIFT (Scale Invariant Feature Transform) for that, see > Wikipedia. I just tr

I tried the explicit code. The gist I undersand that I can return values matching booleans on the left using ''#"     1 0 1 #(i.3)0 2 Originally I was trying ] and it's variations to get results, the correct one being #] I see.  '13 :' is a neat utility. I prefer tacit to explicit, so should com

Re: [Jprogramming] How to get actual values instead of booleans from a list?

A slightly more gentle approach to the problem solved as Pascal gave is to use the magical `13 :` construct as shown below; force the first 2 steps into just one line and call the argument y . a=.(>&6) (2+i.9) a# (2+i.9) 7 8 9 10 13 : 'a#y[a=.(>&6) y' NB. 13 : produces a tacit result whe
