2015-10-15 09:50:33 -0500 commented answer how we select an object with mouse pointer in processing video

@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 :(

2015-10-14 08:37:00 -0500 commented answer opencv 3.0 with contrib installation guide

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...

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!

2015-08-24 09:25:42 -0500 commented answer TLD Tracker (aka Predator)

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 !

2015-08-19 03:06:02 -0500 commented question How to speed up TLD tracker in opencv 3 with contrib modules ?

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?

2015-08-19 02:58:51 -0500 answered a question OpenCV 3.0 make error

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 !

2015-08-19 02:12:27 -0500 commented question opencv 3.0 with contrib installation guide

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..!

2015-08-18 09:56:40 -0500 commented question opencv 3.0 with contrib installation guide

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

2015-08-18 07:19:05 -0500 commented question opencv 3.0 with contrib installation guide

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...

2015-08-18 07:14:57 -0500 commented question opencv 3.0 with contrib installation guide

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

2015-08-17 10:02:08 -0500 commented question opencv 3.0 with contrib installation guide

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 ?

2015-08-17 08:59:38 -0500 commented question opencv 3.0 with contrib installation guide

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 !

2015-08-17 08:19:51 -0500 commented question opencv 3.0 with contrib installation guide

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

2015-08-17 07:55:47 -0500 commented question opencv 3.0 with contrib installation guide

Done that extra modules part with no problems.

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

2015-08-17 07:45:04 -0500 asked a question opencv 3.0 with contrib installation guide

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 !

2015-08-17 07:09:12 -0500 commented question How to configure opencv 3.0 with codeblock 13.12 - Win7

I dont know, im using latest mingw for windows32

2015-08-05 04:49:27 -0500 commented question How to configure opencv 3.0 with codeblock 13.12 - Win7

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 !
