Edit C++ file

Offer an edited version of the .cpp file at [login to view URL] Ideally: i) which allows the indexing stage to proceed even if it comes across an image it cannot process, and ii) reports when complete a list of these problematic images as a text file. I can provide a Dockerfile which compiles the full code (compiling from source should not be attempted) and instructions on use, as well as sample images. Or am happy to test the edited code myself. The code is designed to faciitate image matching. The indexing process proceeds in phases. This is phase 1, but will fail if the code does not like a particular image. Using imagemagick pre-proessing fails to detect what it does not like, and at the moment we can't tell on what image the code fails.
