蒙特卡洛方法估计运动目标速度的仿真，给出了仿真结果和CRLB。(Monte Carlo method to estimate moving target simulation, the simulation results and CRLB.)

Add Gaussian white noise (mean=0 and variance=0.05 ) to the image using imnoise command. Now use fftshift command to put all zero frequencies in the middle. Low-pass filter this function by applying a mask saving only the central Fourier coefficients. Set the mask width to 255 and create the filtered image.
