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