摘要
介绍了二维离散小波变换的一般形式 ,在图像分解的基础上 ,分析了二维小波变换在医学图像消噪和图像增强中的应用 ,同时给出应用实例。结果表明 ,应用小波分析进行医学图像处理 ,能够有效地改善图像质量 。
Two-dimensional discrete wavelet transform is introduced. Based on the image decomposition, the noise elimination and the enhancement of the medical image are analyzed. An applicational example is given. Results show that medical image processing with wavelet analysis can effectively improve the image quality and is much benefit to diagnosis and therapy of the state of an illness.
