  I was using the OpenCV to predict the motion of a ball seen with a webcam. However I keep getting an error on the cvKalmanPredict state, so I simplify the code into these few lines and try to test the filter solely:CvKalman* kalman = cvCreateKalman(6,3,1);kalman->temp2 = cvCreateMat(1, 1, CV_32FC1);float alpha = 0.1, beta = 0.2;float kalmA[] = {1.0+t0/t1, 0, 0, -t0/t1, 0, 0,0, 1.0+t0/t1, 0, 0, -t0/t1, 0,0, 0, 1.0+t0/t1, 0, 0, -t0/t1,1, 0, 0, 0, 0, 0,0, 1, 0, 0, 0, 0,0, 0, 1, 0, 0, 0};float kalmB[] = {0, 0, 1, 0, 0, 0};float kalmH[] = {1, 0
