A demo backend focused app for eliminating duplicate images with Dagger2, Architecture including MVVM, Paging, LiveData, Room, Paging, and a custom dupe detector integrated with the Glide recyclerview preloader written in Kotlin. It uses a modified dhash fingerprint algorithm to get matches within epsilon in C++ and coarse grained synchronization with coroutines in Kotlin.

  • [coroutines] I am able to match colorized images and some variations in resolution within a hamming distance of 3. I also reduced the search for similar images to within +/- 1 of the population count of the hash. I was able to refactor from a critical section and an ExecutorService to Kotlin coroutines and coarse grained synchronization, reducing dhash times 99%! (3s to .006s)

Edo v1.28 (POC demo portfolio app)

Building a dhasher library within an image download API

Target 28 SDK 14+, Oreo compatible, for phone and tablet

  • Dagger2 for DI abstraction
  • Roboelectric, Espresso, and Mockito tests
  • Paging boundary callback for Room/Retrofit decision making
  • MVVM, Repository, DAO patterns with LiveData for lifecycle managment
  • Glide RecyclerView integration library for image preload
  • Kotlin extensions and coroutines
  • Image duplicates removal built in at preload

Designed with the Material theme and latest, greatest android libs for best viewing pleasure!
