Problem creating GUI Qt after using matrix on C++

  • Hello everyone, it's been over two months since I'm working on a project in C + + (recognition of geometric shape by detecting the contour, the convex hull, the surface of the object), using well Qt creator. And then we trying to create a GUI with Qt, it does not detect the functions that I used, eg "findcontours" and even reporting matrix "Mat src". From my research on the net, most interfaces use only pointers while my entire program is based on matrix. There is not a solution to my problem?

    Hi and welcome to devnet,

    Are you using OpenCV ? If so, are you setting up your project correctly to make use of it ?

    If not you need to at least tell what libraries you are using and a sample code that fails.
