2015-12-13 01:24:18 -0600 | commented answer | Enable Multithreading with TBB during cascade training i dont think GPU is needed, negative sampling parallelization, at least with duplicates, would solve main problem. |
2015-12-13 01:24:04 -0600 | commented question | opencv_traincascade (neg)image reader parallelization Still no progress here? Btw one of methods to erase duplicates is make second pass on sampled negatives, it wont take long at all comparing to sampling time. |

2013-05-16 05:50:02 -0600 | asked a question | 2.4.5 with TBB under MinGW in Windows compilation did not work as well Hello, been trying to compile OpenCV with TBB and here is what i get: What i am wrong at? |
2013-05-15 14:05:00 -0600 | asked a question | 2.4.5 with TBB windows x64 (Windows 7) installation problem I am trying to install OpenCV for 2 days now. I am using Visual Studio 2012, have Python and all needed libraries, downloaded TBB and few others which i dont need. CMake does not add up TBB, it downloads something and asks me only about TBB_STDDEF_PATH, and i add him a path to tbb_stddef.h file. I have these path variables added: OPENCV_BUILD: C:\OpenCV\opencv\build OPENCV_DIR: C:\OpenCV\opencv\build\x64\vc10 (tried withh vc11 as well) PATH: ...;%OPENCV_DIR%\bin; Just in case i copied all \x64\vcXX\lib files to \Debug and \Release subdirectory, for all vcXX both x86 and x64. I am constructing Build to C:\OpenCV\Build directory. All i need are applications compiled for TBB, opencv_traincascade.exe mostly. Im coding on python, so i dont need rest for now. After CMake generation done, i close it, open VS2012, wait until all dependencies being scanned and press Build button for either debug or release and here the most errors i get: Ошибка 33 error LNK1104: не удается открыть файл "....\3rdparty\lib\Debug\tbbd.lib" C:\OpenCV\Build\modules\core\LINK Ошибка 82 error LNK1104: не удается открыть файл "....\lib\Debug\opencv_core245d.lib" C:\OpenCV\Build\modules\imgproc\LINK in english would be something like "cannot open file" So what i am doing wrong? |
