The existing methods for designing two-dimensional digital filters are outlined anda new method——composite method——is proposed. This method has following advan-tages: (1) its computation cost is low; (2) it is easy to acquire lineur phase performance; ( 3 ) it is conient to be generalized to multi-dimensional ones; and so on. Some expe-rimental results show that it can get better results with lower computation cost than two-dimensional window method. Therefore, it applies no only to image processing systems...             本文概述了设计二维数字滤波器的已有的几种主要的设计方法,提出了一种简单的设计方法——组合设计法。这种方法具有计算代价低、易于实现线性相移、便于向多维推广等优点。实验结果表明:这种方法比二维窗口法计算代价还低、设计效果更好。它不仅适于在图像处理或其他计算机系统中作为应用软件使用,也适于在涉及二维或多维数字滤波的研究工作中采用。 文摘来源          A design approach cf linear phase 2-D recursive digital filter banks has been proposed in the paper.The design is based on the transfer function which adopts the Besel function of S domain as its original lowpass filter.By bilinear transformation of 1-D S domain to 2-D Z domain to the function,a linear phase 2-D recursive digital filter can be realized.The realized 2-D IIR filters not only keep the advantages of the linear phase charateristics in the pass band and approximately linear phase charateristics i...             提出一种线性相位二维递归数字滤波器组的设计方法.这种设计是以 S 域一维(1-D)贝塞尔函数为原型的低通滤波器的传递函数,通过一维 S 域至二维 Z 域的双线性变换,实现线性相位二维递归数字滤波器.所实现的二维数字滤波器不仅保持贝塞尔滤波器通带内相位线性、阻带内相位近似线性的优点,而且能利用一维至二维的双线性变换压缩过渡带,使过渡带变得陡峭、阻带衰减增加.采用本文的设计方法,利用低阶的线性相位递归数字滤波器组,即可实现高性能的二维分析与综合数字滤波器组,完成图象的子带分割与重建功能.计算机仿真实验证明所提出的设计方法是正确的、有效的. 文摘来源          The approaches of design and realization about novel two-dimensional(2-D) recursive digital filter banks──2-D leapfrog have been proposed in the paper.The advantages of the 2-D filter banks are:causal realization──to realize real time image analysis and synthesis,linear phase──to avoid the image phase distortations caused by presented 2-D IIR filtering,and stable under nonlinear conditions──they are no overflow or limit cycle oscillations.Practical experiments of image processing have showed that the theory...             本文提出一种新的二维递归数字滤波器组──二维跳耦型数字滤波器组的设计与实现方法。这种数字滤波器组的特点为：因果型──可用于实时图像分解与重构；线性相位──可避免传统的二维ＩＩＲ滤波引起的图像的相位畸变；非线性条件下稳定──有限字长实现二维数字滤波器组时，不存在溢出或极限环振荡。实际的图像处理实验证明，本文提出的设计理论及实现方法是正确的、有效的、可行的。 文摘来源   << 更多相关文摘
