| 摘 要： | 目的：研究Pal类模糊算法的图像增强原理，提出适合CT／MR图像的快速增强算法．方法：首先，通过定义一个线性映射函数，将感兴趣区域（ROI）从背景区域分离出来；其次，用线性的广义模糊算子（L-GFO）单独对ROI进行增强．结果：在P4—2．4G／512M／128M微机上，用IDL对50幅CT／MR图像处理速度进行测试，本文算法平均每幅增强处理用时约0．8ms．结论：本文算法减少了运算量、提高了处理速度．

| Abstract: | AIM: To study the image enhancement principle of Pal fuzzy algorithms and to propose a fast fuzzy enhancement algorithm fitting for CT/MR image. METHODS: The region of interest (ROI) was separated from the region of background by a novel linear mapping function and further enhanced by the linear general fuzzy operator. RESULTS: Fifty CT/MR images were implemented in IDL on a PC with Intel Pentium 4 2.4 GHz, 512 M RAM and 128 M RAMDAC, which revealed that it took about 0.8 ms to enhance each image using the algorithm proposed. CONCLUSION: The algorithm presented by this paper reduces the computation load and speeds up the process. |
