Hi all,
I have been recently looking at and experimenting with DMIP, and I have a basic question:
Suppose my task is to extract 2 columns from an Image, and add them. This I would like to do in a loop, for a different
image each time, but same column index.
It is easy to write a graph for this.
However, if using DMIP, after the source node that stores the image,
1) what node type should I use for the columns?
2) Can I overload the "add" to operate on columns?
Further, in the "classical IPP" based thinking, I would have used the GetRow/Columns for the line extraction, and ippsAdd variants for the
additions. Do I still use these, or I can use the loop based C-style summation and colums extraction, and rely on DMIP to substitute with an appropriate code?
Thanks,
Sid.

Hi Sid,
By "columns" do you mean real pixel-wide column or sub-picture of specific width and whole image height ? DMIP is generally oriented on processing images by horizontal slices. This kind of operations better uses CPU cache.

Sergey
