说明：  针对稳健高斯回归滤波器运行速度过慢的问题，利用截断高斯权函数的快速卷积提高了算法 运行速度。在详细分析稳健高斯回归滤波器和卷积函数的基础上，推导了截断高斯权函数，并通过实验 确定了合适的参数值。
(convolution of the truncated Gauss weight function is used to improve the algorithm. Running speed. Based on the detailed analysis of the robust Gauss regression filter and convolution function, the truncated Gauss weight function is derived and tested. The appropriate parameter values are determined.)
