  • Simplifies the caching logic for both CPU and GPU based matching.
  • Introduces a new thread-safe LRU cache that allows to efficiently cache the FLANN-based descriptor index for CPU-based matching. As a result, CPU-based matching speed improves by ~20-30%.
  • Extracts the FLANN-based descriptor index as a separate interface and adds test coverage.
  • Fixes a race-condition in the dense reconstruction workspace cache.
