I am using opencv for image processing, while comparing images by using command compareHist i am getting the following error:

OpenCV Error: Assertion failed (H1.type() == H2.type() && H1.type() == CV_32F) in compareHist, file /home/alishba/opencv-2.4.9/modules/imgproc/src/histogram.cpp, line 1985 terminate called after throwing an instance of 'cv::Exception' what(): /home/alishba/opencv-2.4.9/modules/imgproc/src/histogram.cpp:1985: error: (-215) H1.type() == H2.type() && H1.type() == CV_32F in function compareHist
