2013-12-28 15:34:43 -0600 asked a question Fastening haartraining speed

Hello, I am now making a object-recognizer using opencv_haartraining. I have opencv 2.4.6.1 in my mac OSX, and the training is going on well.

Though, I do not have so much time until the deadline, and would like to enhance the training speed of opencv_haartraining.

Now I am typing in the option "-mem 3000" in the last part of the command, but the training is only using around 100MB.

Is there any ways so that I can use more memories to train? Or any others ways to fasten the training speed would be great!!

I am looking forward for all your tips. thank you.

2013-12-28 03:58:07 -0600 asked a question Compile errors for installing opencv 2.1 for macOSX

Hello, I am a student in Tokyo, and am suffering for some errors I am getting for compiling opencv 2.1. I have little time for my work and am urgent to now some tips.

For the program I am making, I am using opencv 2.4.6.1. The OS is mac OSX ( ver 10.8.5 ) I had no difficulties installing opencv 2.4.6.1.

Though, I am making a object recognizer using haartraining and having trouble using enough memories. ( I am writing -mem 3000" but am only using 100MB now.) If my research is not wrong, there seems to have been some bad updates since opencv 2.1 so that you can not set the memories to use.

Is it ok to install both opencv 2.4.6.1 and 2.1 in one machine? And if so, there are some problems I am facing after some challenges installing opencv 2.1.

I entered the following command

$ wget http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.1/OpenCV-2.1.0.tar.bz2/download $ tar zvf OpenCV-2.1.0.tar.bz2 $ cd OpenCV-2.1.0 $ cmake . $ make install

and got the errors below...
