+gpu::buildWarpPerspectiveMaps
+-----------------------------
+Builds transformation maps for perspective transformation.
+
+.. ocv:function:: void buildWarpAffineMaps(const Mat& M, bool inverse, Size dsize, GpuMat& xmap, GpuMat& ymap, Stream& stream = Stream::Null());
+
+ :param M: *3x3* transformation matrix.
+
+ :param inverse: Flag specifying that ``M`` is an inverse transformation ( ``dst=>src`` ).
+
+ :param dsize: Size of the destination image.
+
+ :param xmap: X values with ``CV_32FC1`` type.
+
+ :param ymap: Y values with ``CV_32FC1`` type.
+
+ :param stream: Stream for the asynchronous version.
