摘要
介绍了一种恢复数字化畸变凸性图像的算法—增强算子 讨论该方法增强和恢复被高斯噪声畸变的凸性数字化图像的原理 并通过计算机模拟实例验证了增强算子处理畸变凸性数字化像点的有效性．该方法已用于处理Ａｌ－Ｍｎ－Ｓｉ准晶的数字化高分辨电子显微镜（ＨＲＥＭ）像。
An algorithm named enhancing operator for restoring digitized images with degraded convex is introduced.The principle of the enhancing operator for enhancing and restoring digitized images with con- vex bright-dots perturbed by additive Gaussian noise is discussed. The computer simulation show that the al- gorithm has good functions for noise reduction,restoration and enhancement of convex image spots in digitized images. The enhancing operator has been previously used to process the digitized high-resolution electron microscopic (HREM) images of Al-Mn-Si quasicrystal and discovered the periodic characteristics in the HREM images.
