摘要
采用一种基于粗糙集理论实现胸部X线数字图象增强的新方法 ,该方法根据粗糙集的条件属性 ,将一幅采用双能量算法获得的肺部软组织X线数字图象划分为不同的子图象 ,然后对各个子图象分别作衬比增强 从结果中可看出 ,采用种方法处理后得到的图象效果较为理想 ,能给临床上的医学工作者提供清晰的图象 。
A new method for image endancement of X ray digital image about chest based on rough set has been studied.It takes a pulmonary image gained by arithmetic of X ray dual energy into different sub image block besed on rough set,and then makes it enhancement for different sub image.As a result,the image processed by rough set has good details and its contrast has improved.At the same time,it can provide images of fine resolution for clinical practice,and provide some parameter of automatic deagnosis based on computer.
