摘要
针对医学X-光片图像的特点,尤其是乳腺、肾脏等难度较大的图像,在传统方法不甚奏效的情况下,提出了一些新的去除噪声、增强对比度、提取目标图像边缘的方法,不仅改善了图像的视觉效果,而且可获得人眼不能直接取得的信息,得到明显优于以往算法的满意结果,对于疾病的临床诊断,尤其是疑难病的早期发现,具有较高的实用价值。
This paper presented Several image processing methods for medical X-ray pictures: noise removal, contrast enhancement, and contour extraction. These methods, us?d to process X-ray pictures for mammary gland, kidney etc., obtain satisfactory experimental results, while the conventional processing methods are noneffective. Not only the view effect of pictures is improved, but also a lot of useful informations arc got, which are unable to get from normal X-ray pictures with eyes. They are valuble and important for improving clinical diagnosis results especially for that of early phymatosis.
