@berak : are you satisfied with the tracking results you get with the opencv_contrib_modules ? I'm seeing very poor fps on TLD implementation. (that was a few weeks ago, maybe the release changed .. ?)

oh no, not openCV3 again ! i'll try it on the only computer i got it to work on then !

Any news about the project ? @StevenPuttemans

Your question is somewhat imprecise.

Nonetheless, you should look at 'Online Object Tracking' and tracking components for OpenCV.

A tracker like TLD should work : it will start tracking a random object once you initialize a bounding-box around an object, and progressively learn how it looks like from all angles.

Hi, what's "dpm.hpp" ? it doesn't seem to exist in my OpenCV include folder :(

Unfortunately, this doesn't fix the atomic_fetch errors that i am having while buliding OCV3 with contrib modules on a windows7 computer for codeblocks...

Yes, but it's very slow :(

What were you cmake configuration choices? Did you use 'mingw makefile" or another, like codenlocka mingw that creates a project file for opencblibrary configuration?

Thx!

Ill definitly try that new algorithm. It's for openCV3.0 contrib tracking module right?

Will this fix atomic_fetch error ? I think I had already disabled both linedescriptor and dataset modules... I'll give it a try nonetheless !

Same here : Running TLD sample code in openCV 3 with tracking contrib module is giving me unsatisfactory results : Very low framerate even on low quality sample video. Any idea how to speed it up?

if you don't need those particular contrib modules, try deactivating a few in cmake at configuration step. Start by unticking xfeatures2d. (I ended up also unticking datasets, lineprocessor and another one.)

Good luck !

Im glad for you @LBerger, but I want to get it to work on windows ! I've written a thorough installation guide for OCV3/contribs/visual studio/cmake and ill try to post it somewhere. Unfortunately all my screencaps for VS property sheets are in French..!

I have but i get that weird atomic_fetch error. I'm not alone either ! I've seen no one getting OC3 to work with code blocks and contrib modules

So @LBerger it turns out I eventually got installation to work in VS2015 ! With contrib modules and everything (maybe I didn't use the right order to build opencv.sln; ALL_BUILD then INSTALL). Now the tracking sample code runs (although really slow, but that's another issue :) Still no explanation as to why we don't seem to be able to build a solid version of OCV3 for code blocks...! In other words, this question is still left unanswered http://answers.opencv.org/question/63...

How can you get gcc version ? I got latest mingw package from it's site.

Did all that, but when I build project in VS2015 it's giving me plenty of opencv_core alerts and fails to build... Did I miss anything ? I used cmake to configure then generate the opencv project file, specifying where to contrib folder was and other options. What should I look for now ?

Okay, so could you explain the step by step method to get opencv3 with contrib modules to work in VS? First build with cmake then what ? Thx !

Have you successfully built an opencv library with contrib modules using cmake/mingw without unticking WITH_IPP ?

Done that extra modules part with no problems.

Effectively I don't have internet-could disabling IPP be the cause of my issues ?

Hi there,

I've tried a few different methods in order to install opencv 3.0 gold WITH the opencv_contrib modules (I would like to use the tracking ones in particular), none of which seem to work.

Can someone provide me a quick installation guide that he/she has successfully tested on a windows machine ?

What doesn't work for me : - using cmake to build opencv with contrib modules (mingw) and developing in codeblocks (weird atomic fetch error) - trying to use cmake to build visual studio 2015 libraries (building issue when opening cmake built projects)

Each time I build in cmake I seem to have to disable IPP, comment out a line in opencvcompikeroptions.cmake following various answers found here or on stack overflow.

Any ideas as to how to start from scratch ? I've tried same unsuccesfull methods on two machines running win7 and win10

Thanks !

Malcolm

@aware_ignoramus did you find a fix ? Just followed same process on another windows machine (this time win10, and same atomic fetch error ) its driving me crazy !

I dont know, im using latest mingw for windows32

I definitely built the opencv libs using cmake (to get the build to work, I had to deactivate WITH_IPP from cmake configuration and fix a videoio error by commenting out add_extra_compiler_option(-werror=non-virtual-dtor) as suggested in a stack overflow post though.

Now my sample opencv test code won't build either : Undefined reference to atomic_fetch_add_4 . Any ideas most appreciated !

Using opencv3.0, code blocks, mingw, latest cmake. Thanks !
