You can create a view from an image like this:

    rgb8_image_t img( 100, 100 );
    rgb8_view_t  v = view( img );

Creating a view is very cheap and shouldn't produce any overhead. To
create a subview do this:

     rgb8_image_t img( 100, 100 );
     rgb8_view_t  sv = subimage_view( view( img ), 0, 0, 100, 100 );

Hope that helps,
Christian
