Alors voila je galère sur ce programme depuis 2 semaines rien à faire pourtant le programme se compile sans erreur et se génère, et à mon avis c'est bien codé.
Par contre j'ai une erreur à l’exécution du programme du type :
OpenCV Error: Assertion failed (elemSize() == (((((DataType<_Tp>::type) & ((512- 1) << 3)) >> 3) + 1) << ((((sizeof(size_t)/4+1)*16384|0x3a50) >> ((DataType<_Tp>::type) & ((1 << 3) - 1))*2) & 3))) in unknown function, file c:\opencv2.2\include\opencv2\core\mat.hpp, line 563

Est ce que on peut m'aider sur ce sujet svp
