摘要

本文提出了一种新的投影滤波方法，并将其应用于z维数字图像处理中。该投影滤波器将原始图像与其在空间域和频域的一阶投影线性结合。它有一些有趣的特性可以保持整个图像及其每一行和每一列的零频率能量不变。这种投影滤波器可以扩展到保持整个能量不变的-der投影，而不是零频率能量。实验结果表明，该滤波器可用于特征增强和图像压缩。

A novel projection-based filter in digital image processing

A novel projection fiter proposed in this paper is applied in the Z-dimension digital image processing. This projection filter combines the original image with its Iirst-order projection both in the spatial domain and in the frequency domain linearly. It has some interesting properties which keep the zero-frequency energy of both the whole image and its every row and column invariable. This projection filter can he extended to the -der projeetioa that keeps the whole energy invariable instead of the zero-frequency energy. Experimental results show that the proposed filter can be used for feature enhaneement and image compression.
