Lossless and Near-Lossless Image Compression Using Generalized Multi-Context Linear and Nonlinear Prediction

The paper proposes the Multi-ctx2 method, which enables image compression in lossless and near-lossless modes. It employs a generalized multi-context division method in the prediction stage, which is more efficient than other fast prediction methods. Five simple rules for computing the context number have been develope...
