S-L头模型重建，X-CT图像重建算法的仿真研究-SL head model reconstruction, X-CT image reconstruction algorithm simulation

由长度，方差生成用于图像分割的高斯匹配模板，用于匹配滤波增强，做图像分割。(The Gauss matching template for image segmentation is generated by length and variance, which is used for matching and filtering enhancement and image segmentation.)
