本文介绍了使用B样条作为一种工具，在各种数字信号处理应用。简要介绍了B样条理论，讨论了B样条插值和B样条滤波。计算机实现使用一个有效的软件的观点和硬件的方法进行了讨论。最后，实验结果以二维图像格式给出。图像和信号处理的应用包括插值、平滑、滤波、放大和缩小。
This paper presents the use of B-splines as a tool in various digital signal processing applications. The theory of B-splines is briefly reviewed, followed by discussions on B-spline interpolation and B-spline filtering. Computer implementation using both an efficient software viewpoint and a hardware method are discussed. Finally, experimental results are presented for illustrative purposes in two-dimensional image format. Applications to image and signal processing include interpolation, smoothing, filtering, enlargement, and reduction.
