摘要

介绍了一种无损图像压缩系统，该系统由统计模型和算术代码组成。该模型首先通过一个平面对每个像素进行预测，然后收集预测错误的发生次数，以过去的像素形成“上下文”为条件。计数在树中收集，自适应构造，并优化每个像素编码的上下文的大小。

An Image Compression System

A lossless image compression system is described, which consists of a statistical model and an arithmetic code. The model first performs a prediction of each pixel by a plane, and then it collects the occurrence counts of the prediction errors, conditioned on past pixels forming a "context". The counts are collected in a tree, constructed adaptively, and the size of the context with which each pixel is encoded is optimized.
