利用VFSA法对地震剖面进行反演测试，可以用来测试模拟退火法是否可以用于实际模型。(Use VFSA method seismic inversion tests can be used to test whether the simulated annealing method can be used in the actual models.)

添加随机白噪音方法,用于时序仿真分析，仅供参考！(Add noise for simulation)

空域滤波是在图像空间中借助模板对图像进行领域操作，处理图像每一个像素的取值都是根据模板对输入像素相应领域内的像素值进行计算得到的。空域滤波基本上是让图像在频域空间内某个范围的分量受到抑制，同时保证其他分量不变，从而改变输出图像的频率分布，达到增强图像的目的(failed to translate)

子空间算法是语音增强中较新颖的算法，文件对该算法进行了仿真(Subspace method is relatively new in the speech enhancement algorithm, the algorithm was simulated file)
