Problem during make about bgslibrary HOT 20 CLOSED

Hi @Rodrigo-P which version of OpenCV are you using?

from bgslibrary.

3.1.0

from bgslibrary.

Do you have tried the opencv3 branch of bgslibrary?

from bgslibrary.

It gives the same error.

from bgslibrary.

What OS and what version of g++ are you using?

from bgslibrary.

Hi @gustavovelascoh I compiled successfully on a pre-built image with Ubuntu 14.04.4 LTS + OpenCV 3.1.0 + Python 2.7, and gcc 4.8.4. The docker image is available here: https://hub.docker.com/r/andrewssobral/bgslibrary_opencv3/

from bgslibrary.

Hi @andrewssobral, I was asking to @Rodrigo-P, :).. BTW, I have successfully built it using Ubuntu 14.04.4/g++ 4.8.4 and Ubuntu 16.04./g++ 5.3

from bgslibrary.

Thank you @gustavovelascoh ;)

from bgslibrary.

My g++ is 4.8.4 and i'm using ubuntu 14.04 LTS

from bgslibrary.

Hi @Rodrigo-P, one question, the errors when you compile the opencv3 branch are the same of posted initially? because the master branch of bgslibrary is only for opencv 2.4.x.
Usually if you compile the master branch with OpenCV 3 you will get:
[ 1%] Building CXX object CMakeFiles/bgs.dir/FrameProcessor.cpp.o In file included from /home/rodrigo/Downloads/bgslibrary/FrameProcessor.h:29:0, from /home/rodrigo/Downloads/bgslibrary/FrameProcessor.cpp:17: /home/rodrigo/Downloads/bgslibrary/package_bgs/MixtureOfGaussianV1BGS.h:30:3: error: ‘BackgroundSubtractorMOG’ in namespace ‘cv’ does not name a type cv::BackgroundSubtractorMOG mog; ^
This is because the cv::BackgroundSubtractorMOG was removed from OpenCV 3 as you can see here:
cv has no member BackgroundSubtractorMOG
http://stackoverflow.com/questions/28213670/cv-has-no-member-backgroundsubtractormog
To fix this, you need to use the opencv3 branch of bgslibrary. In this branch the MixtureOfGaussianV1BGS algorithm was disabled (and some other issues was fixed also).

This is the error with the opencv3 branch

from bgslibrary.

There is something wrong. Can you please compare your /home/rodrigo/Downloads/bgslibrary/package_bgs/MixtureOfGaussianV1BGS.h file with this https://github.com/andrewssobral/bgslibrary/blob/opencv3/package_bgs/MixtureOfGaussianV1BGS.h

from bgslibrary.

It's the same.

from bgslibrary.

I updated the cmake files from bgslibrary for both opencv 2 and 3 branches.
Please, can you delete your bgslibrary folder and try again by:

git clone https://github.com/andrewssobral/bgslibrary.git -b opencv3
cd bgslibrary/build/
cmake ..
make
cd ..
chmod +x run_video.sh run_camera.sh run_demo.sh
./run_video.sh
./run_camera.sh
./run_demo.sh

This is my output (without warnings):

That's what I thought: OpenCV version is not compatible: 3.1.0
You still compiling the wrong branch of the bgslibrary. This message appears when you are compiling the master branch of the bgslibrary with opencv 3.1.0.
https://github.com/andrewssobral/bgslibrary/blob/master/CMakeLists.txt
Note that the cmake file from the opencv3 branch is different:
https://github.com/andrewssobral/bgslibrary/blob/opencv3/CMakeLists.txt
There are something wrong in your machine, because you are always using the master branch instead of the opencv3 branch.

• master branch (for opencv 2.4.x): git clone https://github.com/andrewssobral/bgslibrary.git
• opencv3 branch: git clone https://github.com/andrewssobral/bgslibrary.git -b opencv3

If you are running git clone https://github.com/andrewssobral/bgslibrary.git -b opencv3 and getting the master branch instead of the opencv3 branch is that there is something wrong with your git clone.
Note that OpenCV version is not compatible: 3.1.0 doesn't exists in the cmake file from opencv3 branch.

from bgslibrary.

It's working now.
I downloaded the zip file and got the right version.

from bgslibrary.

Just one more thing.
I'm going to play around with other videos, how can I make the window resizable?

from bgslibrary.

You can change the parameter input_resize_percent in the VideoCapture.xml file.
<input_resize_percent>100</input_resize_percent> is for 100% (original video resolution).
<input_resize_percent>50</input_resize_percent> is for resizing to 50% of the original video resolution.

from bgslibrary.

Thank you.
