摘要 磁共振成像技术能在体外对疾病进行无损和无创伤检测,但其图像极易被噪声污染,有必要进行增强处理。本文对小波变换进行了介绍,重点分析其在图像增强处理方面的优点,并给出具体的算法实现步骤。最后给出了本算法用于磁共振图像增强的实例,对结果进行了讨论和展望。 Magnetic resonance imaging （MRI）technique can detect the diseases such as cancer in vitro invasively,but the images often contain noises and need to be enhanced. This paper introduced wavelet transform and focused on its application on image enhancement. Concrete algorithm steps are described. Finally,we shos the actual processing results.
