Blob Detection Library use
Jul 10th, 2009, 10:07am  
Hi, I was trying to write some code for detecting blobs (it's driving me kind of crazy) and suddenly found there's already a library for it, but.. well... I'm not that much of a programmer... and couldn't really understand how to use it :S.

http://processing.org/discourse/yabb2/num_1115194160.html

http://www.v3ga.net/processing/BlobDetection/

There is the post where it was uploaded and the site of who created it.

What I need to do is obtain the centroid of every blob on the image im analyzing (then work further with those centres). But I dont really know how to make the library work or to get information from it!

Do any of you know how to.. dunno, get those points and put them into an array or something similar

Thanx.

you coyld try flob, ease use, not listed on p5 site so no one knows abot it, but already many proyects going,..

uses floodfill to tag and image and tracks blobs, centroids and more stuff
check it at s373.net/code/flob

if you want more you should look opencv, artoolkit, etc, etc
hope it helps

That's http://www.s373.net/code/flob/flob.html
For some reason, the address without www part just hang (on my browser). I see they gave a similar address in their code, they should fix their server.
Interesting library, thanks.

hi philo

thanks for the encoragment. yeah, the link, i am moving to a new server real soon, and perhaps other systems, but the dir struct will maintain, so, for now, index.html is a simple redir to the flob.html page.

the lib is also extending a bit, a new version should have more binarize methods, fadein/fadeout params, blob thresh settable, and more stuff i've been tracking down from a lot of recent projects using it. btw, some fun stuff here using flob if you have some spare time:) http://osomdopensamento.wordpress.com/projectos/ (in pt...)

best regards
