Detailed Description

An in-memory implementation of openMVG::sfm::Regions_Provider.

OpenMVG's default Regions_Provider loads feature regions from disk (.feat / .desc files). This subclass instead holds regions directly from the image describer output, completely eliminating disk I/O from the feature-extraction-to-matching handoff.

The SfM engine and all matcher classes accept a shared_ptr<Regions_Provider>, so dropping an InMemoryRegionsProvider in place of the default one requires no other changes to the OpenMVG pipeline.

Usage: auto provider = std::make_shared<InMemoryRegionsProvider>(); for each image i: auto regions = describer->Describe(image); provider->add(i, std::move(regions)); pass provider to matcher and SfM engine
