一种实用高效的二维FIR滤波器

Design and Application of a Practical and Efficient 2-D FIR filtering

本文提出了一个适用的、高效的二维FIR数字滤波器的设计新方法,此方法的基本原理是冲击响应舍入法,它与传统的设计方法相比,大大地节省了计算时间,提高了效率。文中详细讨论了新滤波器的实用性,并通过在服装逢缝处皱褶信号获取的信号处理上的应用,证实了它的可性行。

A new practical and efficient 2-D digital FIR filter is designed.The new method based on impulse response rounding is expressed intensively,which reduces the computational time significantly as compared with the conventionalmethod.Practicality of the new filter discussed in detail.The advantage of the new method is demonstrated by an example of obtaining the pucker signal of garment seams.
