System information (version)

OpenCV => 4.5.0
Operating System / Platform => MacOS
Compiler => Android Studio with ndkBuild

Detailed description

I am developing and android app, I am using openCV android sdk along with some cpp files that process some images, building with ndkBuild all of the files. Now that I updated from OpenCV-3.1-android-sdk to OpenCV-4.5.0-android-sdk I cannot find a function called cvDiv and a class called cvMat. Can you tell me the equivalent ?

I am using these includes:

#include <opencv2/core/core.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/highgui/highgui.hpp>

In my cpp file was using it like this:

CvMat src = srcImg;
CvMat mask = CannyImg;
cvDiv(&src, &mask, &mask, 256);

My partial solution: #include <opencv2/core/core_c.h> -> for cvDiv

But what about cvMat. If I just changed it to Mat cvDiv will complain that it cannot handle that class

I am using these includes:

#include <opencv2/core/core.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/highgui/highgui.hpp>

In my cpp file was using it like this:this (So basically I had this code working in openCV 3.1.0):

Mat srcImg = mGray;
mat1 = new Mat(..);
Mat CannyImg = *mCanny;
mat2 = new Mat(..);
CvMat * src = srcImg;
mat1;
CvMat * mask = CannyImg;
mat2;
cvDiv(&src, &mask, &mask, 256);

My partial solution: #include <opencv2/core/core_c.h> -> for cvDiv

But In openCV 4.5.0 I get this error:

error: no viable conversion from 'cv::Mat' to 'CvMat *'

I am actually asking: How can I convert this code to run with OpenCV 4.5.0. - I could use divide instead of cvDiv (as @sturkmen stated) - but what about CvMat. If I just changed it to Mat cvDiv will complain arguments do I feed to that it function ? I cannot handle that classfeed Mat, I cannot use CvMat..
