Hi Edward, Yes, we're building this for handling hundreds of thousands images (at least). We're thinking processing of individual images (or a set of images together) will be done in Matlab itself. However, we can use Hadoop framework to process the data in parallel fashion. One Matlab instance handling few hundred images (as a mapper) and have hundreds of such instances and then combine (reducer) the o/p of each instance.
