CSharp OpenCV

1. Конфигуриране на OpenCV със C#.

• Инсталиране на EMGU wrapper
• Инсталиране (Repair) на Microsoft Visual C++ 2010 Redistributable Package (x86)

2. Създаване на проект в C# и добавяне на необходимите библиотеки

• Start->All Programs->MS VS2010 Express -> MS VS2010 Express
• File->New Project->Windows Forms Application->OK
• File->Save

EMGU настройки#Референции

• References->Add Reference->.Net->WindowsBase->OK
• References->Add Reference->Browse->C:/EMGU->emgu...->bin->Emgu.CV.dll,Emgu.CV.UI.dll, Emgu.Utils.dll

EMGU настройки#Зависимости

• C:/EMGU->emgu...->bin->x86->Object of type - exe, dll, ocx) -> преместват се се всички в директорията debug на приложението
• Desktop->nvcuda.dll премества се в директорията debug на приложението.
