| 摘 要： | 在数字成象系统中,如何快速而且有效地实现精确聚焦一直是成象系统研究中的焦点.本文提出了利用增强图象边缘特征来提高精确聚焦能力,并将常见的边缘增强滤波器与以小波变换为基础构建的滤波器进行了比较,实验数据表明,虽然常见滤波器和基于小波变换滤波器都能提高聚焦能力,但后者能更有效地分辨出只有微小的离焦量的图象,有很好的应用前景.

| Abstract: | Itis always theemphasisof research abouthow to realize auto-focus quickly and effectively in imaging system.Thispaperputforward algorithms thatcan enhanceedge features in imagesforim- proving auto-focus capability and compares the usual edge-enhance filters with wavelet-based filters. Experimental data shows that although both the usual edge-enhance filters and wavelet-based filters improve the focus capability the lattercan detectslightly defocused images more effectively.Therefor they have a good future in application. |
