Supplying new images to existing graphs
Is it possible to replace images in an existing graph? Depending on the implementation it could get quite expensive to call vxVerifyGraph everytime a new image requires processing, especially an implementation that optimizes with tiling and fusion. Is there a way to parameterize graphs or something of the sort?

Let's assume we have VxProcessGraph in a loop, you can also modify input parameters of the nodes by accessing their pointers and then process the graph. You don't have to re-validate the graph. For example, you can change pixel values of vx_image at each loop's iteration.
Hope it help you out.
