opencv class "cvKalman" not recognised

Question

I have a problem, in ROS I process a camera feed with openCv. Now i try to implement the cvKalman, but this type is not recognized, however the opencv example works well.

What am i missing, why is not recognized this type?

here is my include to the ROS node:

#include <ros/ros.h>
#include <math.h>
#include <image_transport/image_transport.h>
#include <cv_bridge/cv_bridge.h>
#include <sensor_msgs/image_encodings.h>
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/highgui/highgui.hpp>

#include <opencv2/core/core.hpp>

// for img processing 
#include "opencv2/highgui/highgui.hpp"
#include "opencv2/imgproc/imgproc.hpp"


#include <opencv/cv.h>

Answer 1

I solves the problem by using the KalmanFilter wrapper class, but still I dont understand why I cant use the simple Kalman class.

Answer 2

Try including with "s not <s such as:

#include "ros/ros.h"
