How to use MedianBlur to Mat data CV_32FC1

edit

Hi there

I want to use MedianBlur to CV_32FC1 data. but, it use only 8bit data format data ? what would be a good way to do it?

so, my soce code is this. but , I run this code , and downed the median blure with no error code.

cv::Mat depthMat = cv::Mat(HEIGHT_BASE_PIC, WIDTH_BASE_PIC, CV_32FC1, SDepthImage->depthImage);
//  cv::imshow("******DepthMat******"+cameraID, depthMat / 4500.0f); 
cv::Mat noiseDeletedMatDepth ;
cv::medianBlur(depthMat, noiseDeletedMatDepth,7);

so, how to use medianBlur for 32bit-float depth data ?
