Here's a snippet from something I just wrote

Mat scratch;  // part of the state of the node -- if the image size stays
constant, it will only allocate once

    //PROCESS THE IMAGE
    if (img_bridge_.fromImage(*msg, "bgr8"))
    {
        Mat I = img_bridge_.toIpl();
        I.copyTo(scratch);
. . .
you don't have to deallocate ever (you could ... using scratch.release() but
you almost never need to
