| 摘 要： | 提出和验证一种基于偏振－空间编码方案和多重成像技术的光学方法来实现模糊逻辑图像处理，系统中，模糊变量和它们的补被编码为空间正交分布的两个偏振状态。通过对透镜阵列状态的编程，可以实现两个模糊图像间的模糊逻辑操作。本系统中，两个输入图像被偏振编码为8个编码图像作为输入图像，系统是空不变系统，不需要取阈装置和解码过程，通过引进取阈装置，可以在一层系统中实现两个图像间更为复杂的模糊逻辑操作，并给出了实验结果。

| Abstract: | An optical system based on polarization and area coded scheme and the multiple imaging technique is proposed for fuzzy image processing. In this scheme, each encoding cell is only composed of one encoding cell so that the resultant pattern is still the image in which there is no space between any two pixel rows. All of the fuzzy logical functions of two images can be implemented in parallel and spatial invariant by programming the lens arrays with corresponding modes. In particular, no thresholding device and decoding mask are needed, therefore, the system exhibits a high operation speed and a large information throughout. The experimental results are given. |
