Multithreaded image processing in C++

Question

I am working on a program which manipulates images of different sizes. Many of these manipulations read pixel data from an input and write to a separate output (e.g. blur).

Answer 1

I think map/reduce framework will be the ideal thing to use in this situation. You can use Hadoop streaming to use your existing C++ application.

Just implement the map and reduce jobs.

As you said, you can use row-level maniputations as a map task and combine the row level manipulations to the final image in the reduce task.

Hope this is useful.
