pure virtual |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
dx | First derivative of image in the vertical direction. Support only CV_32S type. |
dy | First derivative of image in the horizontal direction. Support only CV_32S type. |
edges | Output edge map. It has the same size and type as image. |
stream | Stream for the asynchronous version. |
