OpenCV TBB IPP Funzioni OpenMP

Question

Esiste un elenco di funzioni/metodi di OpenCV ottimizzati con IPP e/o TBB e/o OpenMP?

Answer 1

Disclaimer: Non ho esperienza nell'uso di OpenCV.

Non ho trovato alcun elenco sul sito ufficiale opencv.org. Tuttavia, il ChangeLog says:

acceso tutti i restanti cicli paralleli da TBB-solo TBB :: parallel_for() per cv universale :: parallel_for_() con molte possibili backend (MS concorrenza, GDC di Apple, OpenMP, Intel TBB ecc)

Ora, sappiamo cosa cercare e grep -IRl parallel_for_ applicato su opencv directory ci dà la seguente:

build/include/opencv2/core/core.hpp 
sources/apps/traincascade/boost.cpp 
sources/modules/calib3d/src/stereobm.cpp 
sources/modules/contrib/src/basicretinafilter.cpp 
sources/modules/contrib/src/magnoretinafilter.cpp

sources/modules/video/src/bgfg_gmg.cpp 
sources/modules/video/src/lkpyramid.cpp 
sources/modules/video/src/tvl1flow.cpp 

Qui, vediamo la lista dei moduli e parti WHI ch utilizzare il ciclo parallelo. Spero sia sufficiente rispondere alla domanda per TBB e OpenMP. Per maggiori dettagli, apri il file corrispondente e cerca parallel_for_ per scoprire in quali circostanze è applicato.

Quanto IPP, sembra è abbastanza ampiamente utilizzata dalla libreria di base, egrep -IRl '\bipp' pronunciato la seguente:
