[00:41] <plurworldinc> hello world
[00:41] <teddy-dbear> hi again
[00:44] <plurworldinc> it's really quiet in here, lol
[00:47] <rmg51> hard to wake everyone up
[00:49] <plurworldinc> i noticed that , but i guess that is normal, so how are you doing this week
[00:51] <rmg51> doing good
[00:51] <rmg51> but the week just started
[00:58] <plurworldinc> that is true i am beganning my holiday shopping this week and enjoying the fun that goes with my kids second week in school
[00:59] <JonathanD> Hi.
[00:59] <plurworldinc> hello
[00:59] <teddy-dbear> Lo
[01:00] <plurworldinc> everyone having a good night
[01:00] <JonathanD> Sure.
[01:00] <JonathanD> Tired, though.
[01:00] <plurworldinc> tired is good, that means you had a long and productive day, lol
[01:01] <JonathanD> We can pretend that is why.
[01:02] <plurworldinc> \lol
[01:02] <JonathanD> I did get most of the placeholder content done for fosscon 2013 on the ride home.
[01:02] <JonathanD> So I guess I can upload that tomorrow.
[01:03] <JonathanD> at least I did something useful :)
[01:03] <plurworldinc> that is true and it counts
[08:48] <JonathanD> Morning.
[09:03] <rmg51> Morning JonathanD
[09:07] <JonathanD> Hey.
[11:08] <waltman> 46F in Bryn Mawr?
[11:08] <JonathanD> it's cold.
[11:08] <waltman> TOO cold.
[11:09] <waltman> It's a good day to mow mom's lawn.
[11:27] <InHisName> 42 here
[11:27] <InHisName> Cold Morning to you all
[17:12] <ChinnoDog> That is cold. Are you in Canada?
[18:28] <InHisName> To make 2nd copy of home folder from unity, how to do that ?   I want TWO folders up and showing.
[18:45] <rmg51> center click home and a new tab should open
[19:33] <InHisName> Thanks got it. Now done with that.
[19:33] <InHisName> Need to start the folder with sudo,   how to start folders from command line ?
[19:35] <InHisName> Now I remember, name is nautilus
[19:52] <MutantTurkey> the matlab install ls like 5 gb?
[19:53] <MutantTurkey> waltman: that is crazy!
[20:32] <waltman> ?
[20:33] <waltman> MutantTurkey: everything about matlab is crazy.
[20:33] <waltman> 5 gb sounds about right.
[20:33] <MutantTurkey> makes a pain in my butt
[20:33] <MutantTurkey> I don't have 5gb on my partition lol
[20:33] <waltman> I think my largest thumbdrive is 4 gb :)
[20:40] <MutantTurkey> luckily it's installed on tux
[20:41] <waltman> Woot! I've passed the two image processing tests my soon-to-be postdoc advisor has thrown me!
[21:42] <jedijf> is 'test' phD speak for pro bono
[21:45] <waltman> An excellent question.
[21:45] <waltman> He told me afterwards that he gave me the simplest example he had just to see if I could figure out how to process the images.
[21:56] <MutantTurkey> waltman: you go girl!
[21:56] <MutantTurkey> waltman: you go girl!
[21:56] <MutantTurkey> what were the tests?
[21:56] <MutantTurkey> Image processing is awesome. I think I want to return to drexel to do my masters and do some research in the Graphics and Vision lab again
[21:57] <waltman> a) circle all the cells in this image: http://wlad.mawode.com/~waltman/misc/cells.jpg
[21:58] <waltman> That turns out to be easy if you know about edge-detection convolutions.
[21:58] <waltman> I'm not joking. The algorithm is really simple to implement.
[21:58] <waltman> That gave me http://wlad.mawode.com/~waltman/misc/circles_sobel.jpg
[22:00] <waltman> Then he emailed me back asking how I'd make all the cells a different color.
[22:00] <waltman> That's a bit trickier.  The solution I came up with produced this: http://wlad.mawode.com/~waltman/misc/foreground.jpg
[22:01] <waltman> MutantTurkey: One nice thing is that you instantly know if your algorithm worked or not.
[22:01] <MutantTurkey> yes
[22:01] <MutantTurkey> what library are you using?
[22:01] <MutantTurkey> or not
[22:01] <waltman> I used ImageMagick to do the low-level stuff.
[22:01] <MutantTurkey> I love ImageMagick, but it's not very fast
[22:02] <MutantTurkey> for blob detection I found an awesome library
[22:02] <MutantTurkey> called cvBlob (opencv based)
[22:02] <MutantTurkey> it works really really well
[22:02] <MutantTurkey> probably would work for this sort of thing if you needed it
[22:02] <waltman> that takes about 40 seconds on my box
[22:02] <MutantTurkey> one image?
[22:02] <waltman> it's a 1.4 MB tiff
[22:02] <MutantTurkey> http://code.google.com/p/cvblob/
[22:02] <MutantTurkey> yeah makes sense
[22:03] <MutantTurkey> but anyway, If you need to do a lot of it in the future
[22:03] <MutantTurkey> I had good luck with that
[22:03] <MutantTurkey> used it for my drosophila project
[22:03] <waltman> he recommended I read "Digital Image Processing Using MATLAB". It's only $139.95 on Amazon.
[22:03] <MutantTurkey> lol f that
[22:03] <waltman> He said they use another package he likes better than opencv.
[22:04] <MutantTurkey> f matlab f all of that
[22:04] <MutantTurkey> I used Imagemagick and open cv exclusively
[22:04] <MutantTurkey> they are both awesome
[22:04] <MutantTurkey> I use imagmagick mostly for it's built in ops though
[22:04] <MutantTurkey> useful to do basic filtering and stuff like that, before procesisng
[22:04] <waltman> I've never used opencv
[22:04] <MutantTurkey> It is nice, the documentation has been ok
[22:05] <MutantTurkey> https://github.com/mutantturkey/FlyTracking/blob/master/fly-tools/fly-tracker/main.cpp
[22:05] <MutantTurkey> here is a little program that tracks 2 blobs and tells you if they are together or not with cvBlob. I use it on 10 minute vidoes and it completes in less than a minute
[22:06] <waltman> he's got to track the number of blobs you see on that image. only they're cells, and they divide.
[22:06] <waltman> afaict he's one of the world's experts on tracking blobs :)
[22:18] <MutantTurkey> who uses matlab?
[22:18] <MutantTurkey> ok!
[22:18] <MutantTurkey> waltman: wait what is this for again?
[22:19] <waltman> a postdoc for a new prof in Drexel's ECE department
[22:19] <waltman> s/for/with/
[22:20] <waltman> https://pantherfile.uwm.edu/cohena/www/
[22:24] <waltman> OK, I'm heading out to grab a bite to eat. Later.
[22:32] <MutantTurkey> cya!
