摘要
为了能够更好地模拟扫描仪对图像的扫描过程,在分析现有打印机和扫描仪模型的基础上,提出了一种改进的扫描仪模型,主要为改进模拟扫描仪采集数据点过程的线性滤波器。经实验结果证实,该扫描仪模型比现有模型模拟扫描仪扫描输出的图像误差小。
Based on analyzing the existed scanner model,a promoted model is proposed for better imitating the processing of scanner,in which the method of computing a linear filter is promoted,the filter is used to mimic the picking up pixel of scanner. The model is more accurate than past ones what proved by result.
