The novel method of improving the quality metric of protein microarray image presented in this paper reduces impulse noise by using an adaptive median filter that employs the switching scheme based on local statistics characters; and achieves the impulse detection by using the difference between the standard deviation of the pixels within the filter window and the current pixel of concern. It also uses a top-hat filter to correct the background variation. In order to decrease time consumption, the top-hat filter core is cross structure. The experimental results showed that, for a protein microarray image contaminated by impulse noise and with slow background variation, the new method can significantly increase the signal-to-noise ratio, correct the trends in the background, and enhance the flatness of the background and the consistency of the signal intensity. 相似文献

一、继续教育的发展更为迅速在和平与发展为时代主流的国际政治格局下,发展经济,提高本国人民的物质文化生活水平是时代发展的主题。因此,科技和经济的竞争将更为剧烈。而从根本上说,即是教育的竞争和人才的竞争。科学知识的激增、知识陈旧周期的缩短、产业结构的变化、人才流动的频繁,使继续教育的重要性显得更为突出。终身教育、回归教育思想将为更多的人所接受并付诸实践,人的一生变成“学习——工作——学习——工作”循环交替的过程。继续教育以其能够满足人们更新、补充知识、提高工作技能,适应社会竞 相似文献
