| rmg51 | hard to wake everyone up | 00:47 |
| plurworldinc | i noticed that , but i guess that is normal, so how are you doing this week | 00:49 |
| rmg51 | doing good | 00:51 |
| rmg51 | but the week just started | 00:51 |

| JonathanD | Hi. | 00:59 |
| plurworldinc | hello | 00:59 |
| teddy-dbear | Lo | 00:59 |
| 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 | 01:00 |
| JonathanD | We can pretend that is why. | 01:01 |
| 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. | 01:02 |
| JonathanD | at least I did something useful :) | 01:03 |
| plurworldinc | that is true and it counts | 01:03 |
| JonathanD | Morning. | 08:48 |
| rmg51 | Morning JonathanD | 09:03 |
| JonathanD | Hey. | 09:07 |
| waltman | 46F in Bryn Mawr? | 11:08 |
| JonathanD | it's cold. | 11:08 |
| waltman | TOO cold. | 11:08 |
| waltman | It's a good day to mow mom's lawn. | 11:09 |
| InHisName | 42 here | 11:27 |
| InHisName | Cold Morning to you all | 11:27 |
| ChinnoDog | That is cold. Are you in Canada? | 17:12 |
| InHisName | To make 2nd copy of home folder from unity, how to do that ? I want TWO folders up and showing. | 18:28 |
| rmg51 | center click home and a new tab should open | 18:45 |
| 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 ? | 19:33 |
| InHisName | Now I remember, name is nautilus | 19:35 |
| MutantTurkey | the matlab install ls like 5 gb? | 19:52 |
| MutantTurkey | waltman: that is crazy! | 19:53 |
| waltman | ? | 20:32 |
| 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 :) | 20:33 |
| MutantTurkey | luckily it's installed on tux | 20:40 |
| waltman | Woot! I've passed the two image processing tests my soon-to-be postdoc advisor has thrown me! | 20:41 |
| jedijf | is 'test' phD speak for pro bono | 21:42 |
| 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. | 21:45 |
| 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 | 21:56 |
| waltman | a) circle all the cells in this image: http://wlad.mawode.com/~waltman/misc/cells.jpg | 21:57 |
| 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 | 21:58 |
| 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 | 22:00 |
| 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 | 22:01 |
| 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 | 22:02 |
| 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. | 22:03 |
| 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 | 22:04 |
| 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 | 22:05 |
| 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 :) | 22:06 |
| MutantTurkey | who uses matlab? | 22:18 |
| MutantTurkey | ok! | 22:18 |
| MutantTurkey | waltman: wait what is this for again? | 22:18 |
| waltman | a postdoc for a new prof in Drexel's ECE department | 22:19 |
| waltman | s/for/with/ | 22:19 |
| waltman | https://pantherfile.uwm.edu/cohena/www/ | 22:20 |
| waltman | OK, I'm heading out to grab a bite to eat. Later. | 22:24 |
| MutantTurkey | cya! | 22:32 |
