【谷速软件】对于背投探测试验线“幻影” 可以做为参考使用 -[Software] for rear Valley speed detection test line Phantom to use as a reference

that arises the surface coil array. This entropy-based method does not require classification and robustly addresses some problems that are more severe than those found in brain imaging, including noise, steep bias field, sensitivity of arter

1、图像中值滤波实验 ①用imnoise函数在图像’lena.bmp’中值添加椒盐噪声，观测结果 ②用medfilt2函数对含噪声图像中值滤波。 2、使用fspecial函数生成均值、Prewitt、Sobel、Laplacian滤波模板，再用filter2函数对‘cameraman.tif’图像进行空域滤波，显示滤波结果。 3、设计高斯低通和高通频域滤波器，对‘phantom.bmp’图像进行频域滤波，显示滤波结果。然后改变滤波器截止频率，观察对结果的影响。 4、用i

本教程是根据坦克幻影数据由乔恩·纽厄尔。测量数据在一个圆筒形储罐所示。数据可以被认为是2 d因为竖直维度是常数。-This tutorial is based on the tank phantom data contributed by Jon Newell. Data were measured on a cylindrical tank shown below. The data can by assumed to be 2D because the vertical dimension
