Lossless Image Compression Overview and Lepton Optimization for Large‑Scale Storage
The article explains JPEG’s lossy fundamentals, introduces Lepton’s lossless layer and its optimizations—such as arithmetic coding and multithreaded Huffman switching—and describes how vivo’s hybrid physical‑server and Kubernetes deployment achieves roughly 22 % storage reduction across petabytes of JPEG images despite high CPU demands.
