摘要：

A two-stage modelling schema to be used together with arithmetic coding is proposed. The main motivation of the work has been the relatively slow operation of arithmetic coding. The new modelling schema reduces the use of arithmetic coding by applying to large white regions global modelling which consumes less time. This composite method works well and with a set of test images it took only about 41% of the time required by a QM-coder. At the same time the loss in compression ratio is only marginal.
