摘要
目前数字显微镜得到了广泛的应用,强大的图像处理功能和友好的用户接口是其主要优势。为了充分利用医学院校的传统光学显微镜,提出了数字化的改造方法。设计出通过CCD采集、DSP图像处理、视频显示的数字化显微图像分析系统仿真平台。并且根据显微图像噪声特点提出分频的对比度受限直方图均衡算法,从而提高图像的对比度,抑制噪声放大。仿真结果表明,硬件平台可以稳定、有效地增强显微图像,并可达到20帧/秒的处理速度。
Nowaday digital microscopes are widely used because of its powerful image processing function and friendly user interface. In order toimprove the traditional optical microscope utilization of medical colleges, this paper proposes a new way to reconstruct the optical microscopy. An imageacquisition simulation platform is proposed, which uses CCD,DSP and video display as its key parts. Based on the characteristic of microscopic images, itprovides a frequency division contrast limited adaptive histogram equalization algorithm .This algorithm can enhance the contrast of images and restrainnoise. Experiment results show that operating algorithm on this hardware system can enhance the images stably and effectively, and achieve themanipulating speed of 20 frames per second.
