Create a big image capable of containing your input images, then copy each input images to appropriate location of your newly created image using image ROI. After copy display newly created image.

Try hconcat() and vconcat(), you can pass an array of matrix.

I didn't find any documentation, but i use it and it works fine :

Mat appSet;

vconcat(shapesBVec*weights, texBVec, appSet);

and they are int the cv namespace !
