I actually encountered this problem a few days ago. Are you converting your image to greyscale and then converting it to CV_32FC1? Example from my code where Left is a class containing both Mat grey and Mat Frame:

cvtColor(Left.Frame, Left.gray, COLOR_BGR2GRAY); Left.gray.convertTo(Left.Frame, CV_32FC1);

For convertTo you need to include #include <opencv2/core/mat.hpp> and for cvtColor you need to include #include <opencv2/cudaimgproc.hpp>.
