摘要
从平均的角度，定量分析了量化误差效应对数字图象处理的影响，导出了平均量化误差和量化误差概率的计算公式，可指导具体的算法设计和定量分析量化误差．
From the point of average view, the paper analyzed the quantity error effect on digital image processing quantitatively and deduced the fundamental computationformulas for average quantity errors and for the probability of quantity errors to direct thedesign of computation and to analyse the quantity errors.
