OpenCV related DLL in MinGW & VC 2005 Express
I used to MATLAB programming for a long time. I began to find an alternative when the limitations of it arise. I had focused on mixed programming which is still an interest of me. Using C/C++,Fortran,Lisp become a choice when I evaluated various integrated software environments more or less. OpenCV is a wonderful package for image processing and computer vision both in Widnows and in Linux. Linux has a much easier mechanism to develop and use shared library (dynamically linked library) than that in windows. I had planned use Linux as my working platform substituting windows for a long time. But even now I had to return to windows for some work because the surrounding environment is full of date and formats created with products of M$. Fortunately there are lots of Linux tools which can be used in Windows. MingGW is on
