Building Highly Scalable Facial Recognition Pipelines
summary
A lightweight Python framework called deepface implements a full five‑stage pipeline (detection, alignment, normalization, representation, verification) and ships seven recognition models and five detectors under an MIT license; it has 2,000+ GitHub stars and 250,000+ pip installs. VGG‑Face yields 2622‑dim embeddings that deepface returns as vectors; distances and thresholds determine matches. For scale the recommended stack stores embeddings in Redis or Cassandra and uses ANN engines (Annoy, FAISS, NMSLIB, Milvus, Pinecone, Elasticsearch) or Hadoop/Spark for exact k‑NN on very large datasets.
