In OpenCV4Android you can use Imgproc.resize(src, dst, dsize) or Imgproc.resize(Mat src, Mat dst, Size dsize, double fx, double fy, int interpolation)

Just in case you use JavaCV may be you can find your answer HERE.

The same call: Imgproc.resize() throws an Exception:

OpenCV Error: Assertion failed (func != 0) in cv::resize, file ........\opencv\modules\imgproc\src\imgwarp.cpp, line 1910...

Maybe you know why? Thx
