InHisNameThanks got it. Now done with that.19:33
InHisNameNeed to start the folder with sudo,   how to start folders from command line ?19:33
InHisNameNow I remember, name is nautilus19:35
MutantTurkeythe matlab install ls like 5 gb?19:52
MutantTurkeywaltman: that is crazy!19:53
waltmanMutantTurkey: everything about matlab is crazy.20:33
waltman5 gb sounds about right.20:33
MutantTurkeymakes a pain in my butt20:33
MutantTurkeyI don't have 5gb on my partition lol20:33
waltmanI think my largest thumbdrive is 4 gb :)20:33
MutantTurkeyluckily it's installed on tux20:40
waltmanWoot! I've passed the two image processing tests my soon-to-be postdoc advisor has thrown me!20:41
jedijfis 'test' phD speak for pro bono21:42
waltmanAn excellent question.21:45
waltmanHe 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.21:45
MutantTurkeywaltman: you go girl!21:56
MutantTurkeywaltman: you go girl!21:56
MutantTurkeywhat were the tests?21:56
MutantTurkeyImage 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 again21:56
waltmana) circle all the cells in this image: http://wlad.mawode.com/~waltman/misc/cells.jpg21:57
waltmanThat turns out to be easy if you know about edge-detection convolutions.21:58
waltmanI'm not joking. The algorithm is really simple to implement.21:58
waltmanThat gave me http://wlad.mawode.com/~waltman/misc/circles_sobel.jpg21:58
waltmanThen he emailed me back asking how I'd make all the cells a different color.22:00
waltmanThat's a bit trickier.  The solution I came up with produced this: http://wlad.mawode.com/~waltman/misc/foreground.jpg22:00
waltmanMutantTurkey: One nice thing is that you instantly know if your algorithm worked or not.22:01
MutantTurkeywhat library are you using?22:01
MutantTurkeyor not22:01
waltmanI used ImageMagick to do the low-level stuff.22:01
MutantTurkeyI love ImageMagick, but it's not very fast22:01
MutantTurkeyfor blob detection I found an awesome library22:02
MutantTurkeycalled cvBlob (opencv based)22:02
MutantTurkeyit works really really well22:02
MutantTurkeyprobably would work for this sort of thing if you needed it22:02
waltmanthat takes about 40 seconds on my box22:02
MutantTurkeyone image?22:02
waltmanit's a 1.4 MB tiff22:02
MutantTurkeyyeah makes sense22:02
MutantTurkeybut anyway, If you need to do a lot of it in the future22:03
MutantTurkeyI had good luck with that22:03
MutantTurkeyused it for my drosophila project22:03
waltmanhe recommended I read "Digital Image Processing Using MATLAB". It's only $139.95 on Amazon.22:03
MutantTurkeylol f that22:03
waltmanHe said they use another package he likes better than opencv.22:03
MutantTurkeyf matlab f all of that22:04
MutantTurkeyI used Imagemagick and open cv exclusively22:04
MutantTurkeythey are both awesome22:04
MutantTurkeyI use imagmagick mostly for it's built in ops though22:04
MutantTurkeyuseful to do basic filtering and stuff like that, before procesisng22:04
waltmanI've never used opencv22:04
MutantTurkeyIt is nice, the documentation has been ok22:04
MutantTurkeyhere 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 minute22:05
waltmanhe's got to track the number of blobs you see on that image. only they're cells, and they divide.22:06
waltmanafaict he's one of the world's experts on tracking blobs :)22:06
MutantTurkeywho uses matlab?22:18
MutantTurkeywaltman: wait what is this for again?22:18
waltmana postdoc for a new prof in Drexel's ECE department22:19
waltmanOK, I'm heading out to grab a bite to eat. Later.22:24
