摘要
以缩微胶片作为存储介质的病案,因其具有保存时间长、节省空间等优势而被医院广泛应用。然而在存储过程中受多种因素的影响,缩微病案可能出现字迹图像模糊不清的问题,大大降低了它的使用价值。本文介绍了3种图像处理方法,通过对数字化的缩微病案进行图像修复处理,改善其清晰度,从而提高病案信息资源的利用率。
The medical records that are conserved with microfilm as medium have been applied by many hospitals because they can be conserved for a long time and save much space. However, on account of several factors, the words and pictures on the microfilmed medical records may be unclear, which, will probably make the records less valuable in use. We introduce three kinds of image processing methods to solve this problem. The distinctness of the digitalized microfilmed medical records will be improved after the processing of image inpalnting. Thus the information resource of medical records will be used more extensively.
