similar to: patent on 3D floodfill?

Dear R users, I'm trying to do some sort of "floodfill" or "seedfill" with data stored within a matrix in R (usually floating numbers), where a marker value is given to specify the limits of an area to be filled. A reduced example may demonstrate this below. Although I wrote a simple C function for this, it would be very helpful to find a more professional solution.

<WARNING: Long message ahead> Well, I have actually done something the past 1 1/2 week. I've created a program that runs several filters over an image to extract edge information. Currently it loads any uncompressed grayscale TGA file, and spits out another uncompressed greyscale TGA file that is 255 at places where there are edges, and 0 where there are not. I managed to get out quite

Hi everyone, first of all, I searched through the archives for any posts resembling this, I didn't read all posts about the patents so if this has been suggested before I apologise. I read in an article on C|Net (I think, it was linked from Slashdot anyway) that Thompson are threatening to sue you if Ogg Vorbis becomes a success. Which is evil, and I'm also mad at them because they never

This idea is so simple that I'm sure it must have been thought of before, and discarded, since AFAIK it's not used anywhere. I did a quick web search but that didn't turn up much, so I figured I'd put it up for discussion here anyway. How about using large-scale repetition in audio compression? I'm thinking of redundancy in repeated pieces of a song, ie a chorus.

yes, you are right. i always search for quick and easy solution and forget in the meantime that vorbis is a low level codec library. so probably a wrapper lib is the right way. but as far as i understand vorbisfile is already a bunch of convenience functions? so to speak a wrapper lib ? so why not enhance a little bit vorbisfile ? and - i did not felt personally attacked. i just wanted to note

data. On closer inspection (should have done that before, sorry), the procedure uninterleave that you gave is a direct translation of that code, and it also uses little endian (the high byte is at address i*4+1, the low byte at i*4, hence the little byte first, little endian). Procedure uninterleave_little_endian uninterleaves as well, but assumes that the machine it's running on is

As I said in the other thread (for people using threaded mail)/in my last mail (for the rest), I'm working on the "split up the frames into textured triangles and output textures and coordinates" idea. The idea is to find edges in the image. So far I have a Sobel edge detector, a wavelet transformer (to compress the textures, still very incomplete, transform only), and some

Me again, this time not about patents but about wavelets. I've been doing some work on an image compression method which uses Haar wavelets plus VQ and entropy coding, and Segher Boessenkool told me in a private message that you are also doing a video codec. So I searched the archives and read a bunch of posts, but I never did find out any web address. And it's not on xiph.org either. So

I hate following up to myself, but I thought a clarification of one point (specifically WRT RC5 which was mentioned in the original question) might be worthwhile...because what I should have said originally was that "To the best of my non-legally- admissible knowledge, however, none of the algorithms in the current *OpenSSH* implementation are currently encumbered by patents that would

Hi. I need to execute a function from within a GUI. This seems to be no problem but this function takes about 4 minutes to finish, which means the application doesn't react at all, while the function is running. Can I execute a function as a separate Thread, while keeping control(e.g. a reference) of it at the same time? If not, how do this with a class containing this function? thanks,

Dear R Users, I am trying to obtain a best-fit analytic distribution for a dataset with 11535459 entries. The data range in value from 1 to 300000000. I use: fitdistr(data, "gamma") to obtain mle's for the parameters. I get the following error: Error in optim(start, mylogfn, x = x, hessian = TRUE, ...) : non-finite finite-difference value [1] And the following warnings:

Hi, Here''s two blog posts for those that need to test respond_to blocks and/or are currently using simply_helpful extensively. http://blog.methodmissing.com/2006/11/22/testing-different-content- types-with-rspec http://blog.methodmissing.com/2006/11/23/using-simply_helpful-with- rspec-controller-tests - Lourens

Hi Lourens, I fixed the YUV conversion and added a 'skip-empty-bitplanes' feature. The latter is still buggy, I have to check this again. But images look mach better now, even if you use higher compression ratios. (try ./main 1500 150 150 for a 352x288 image -- the output becomes blurred, but how does it looks when you compress it using jpeg down to about 2kB ...). Source is available

I''ve made a Ruby & Rails syntax coloring module for BBEdit. This is a "Codeless Language Module", so it will only work with BBEdit 8+. It''s basically a giant list of Ruby and Rails keywords, method names, and so on. It''s both Ruby and Rails because BBedit only lets you associate a file type with one language module. The file is available here:

Hello, I was searching the internet for an challenge-response system to authenticate an Openssh session with an hardware token. Now i found this, its very old, so i want to now how's the situation today. I couldn't find much documentation. Re: SSH with SecureID > Is there any documentation I'm missing on how to integrate the two? > We'd love to go with 2-factor

Hello , I have bought a cryptocard and i want to make it work openssh, now I need to initialize my token, install the cryptocard patch ( http://projects.jdimedia.nl/files/openssh-cryptocard.patch). The patch reads it's data from a file I've heard that some users made a conversion script from the CryptoADMIN server export to a crypto users file that the patch want. Is there anybody who can

Hello, I have to find a solution logon through OpenSSH to OpenBSD machines from anywhere in the world (unsave computers). So I think I must use a challenge-response system with an hardware token that isn't connected to the computer. I do not want to use a RSA ACE/SERVER, so i can't use SecurID ? I can't use challenge response mode with cryptocard, because I want to protect it against
