list of corresponding dictionaries.
Performs marker detection in the input image. Only markers included in the specific dictionaries
are searched. For each detected marker, it returns the 2D position of its corner in the image
and its corresponding identifier.
Note that this function does not perform pose estimation.
<b>Note:</b> The function does not correct lens distortion or takes it into account. It's recommended to undistort
input image with corresponding camera model, if camera parameters are known
