摘要
现今,各种牙本质粘结剂在口腔科临床得到了广泛应用,并取得了比较满意的效果,而改性牙本质粘结图象的清晰度对牙本质粘结优劣判断起着重要的辅助作用。文章设计了一种基于数字增强技术的改性牙本质粘结图象处理系统,可以对改性牙本质粘结图象进行处理,增强其清晰度。系统先使用扫描电镜采集改性牙本质粘结图象后,送入图象增强模块,此模块采用基于直方图均衡化的数字图象增强方法,对图象进行增强处理。再用通讯模块将增强后的改性牙本质粘结图象送至SDRAM (同步动态随机存储器)控制模块进行保存。最终增强后的改性牙本质粘结图象会在PC主机上进行显示。经验证,该系统能够有效改善改性牙本质粘结图象的质量,使图象更加清晰。针对引入噪声点的改性牙本质粘结图象而言,所设计系统的增强效果仍旧具有良好抗噪性能。
Nowadays,all kinds of dentin bonding agents have been widely used in dentistry and achieved satisfactory results.Tke clarity of modified dentin bonding image plays an important role in judging the quality of dentin bonding.In this paper,an image processing system of modified dentin bonding based on digital enhancement technology is designed,which can process the image of modified dentin bonding and enhance its clarity.The system first uses scanning electron microscope(SEM)to collect the image of modified dentin bonding,and then sends it to the image enhancement module,which uses the digital image enhancement method based on histogram equalization to enhance the image.Then the enhanced image of modified dentin bonding is sent to SDRAM(synchronous dynamic random-access memory)control module for storage.Finally,the enhanced image of modified dentin bonding will be displayed on PC.It is proved that the system can improve the quality of the image of modified dentin bonding effectively and make the image clearer.For the image of modified dentin bonding with noise points,the enhancement effect of the designed system still has good anti noise performance.
