This article introduced X signal gathering different method and the concrete realization, discussed the picture inversion technology in the medicine picture processing function, specifically analyzed the Laplace-transformation, the separate cosine transformation, Hada Masurium transformation and the wavelet transformation. 此外,本文介绍了X线信号采集的不同方法及具体实现,讨论了图像变换技术在医学图像处理中的作用,具体分析了拉普拉斯变换,离散余弦变换,哈达玛变换及小波变换等。
Thus proposed to uses one kind of lifting scheme of wavelet ( two generation wavelet) to carry on the picture inversion. 因而本文提出采用一种提升格式的小波(二代小波)对图像进行变换。
