代码说明:

本文主要研究维纳滤波在图像恢复中的应用。作为常见图像复原方法,维纳滤波采用使复原的图像与原图像的均方误差最小原则复原图像。本文主要通过介绍维纳滤波的基本原理,设计相应的维纳滤波器,实现图像的复原,进行了对退化图像复原的仿真实验,在退化图像中加入了高斯噪声进行恢复,实验表明退化图像在有噪声时必须考虑图像的信噪比,噪声的自相关函数进行图像恢复,才能取得较好的复原效果。

    利用camshift方法实现对一个目标的跟踪,可直接运行,但是效果一般,希望大家能改进一下,相互学习(Achieve a target tracking camshift method, and can be run directly, but the general effect, I hope that we can improve it, and learn from each other)

  • circ_dw
    相控阵天线阵列的密度加权matlab程序代码。 运行gui.m文件 lmax.m和lmin.mLinear_func.m最后几行被调用,放在和Linear_func.m路径相同的文件夹下即可 运行后command window里第一条分割线上面是第一幅图的几个值,第二条分割线上面是第二幅图的几个值。其中,peak_first是数值最大的峰值,peak_second是数值第二大的峰值(第一旁瓣),theta_var是与 peak_first最近的左右两个谷值横坐标的距离。 因为是找半峰值点的,因为都是小数,在数组里没有正好等于主瓣幅值一半的点,只有接近一半的点,所以要设定一个范围比如大0.05或小0.05都认为是半峰值,但是有的数组里0.05的范围还是太小,所以可能报错。(Phased array antenna array the density weighted matlab program code. The last few lines of the run gui.m the file lmax.m lmin.mLinear_func.m call, same placed Linear_func.m path folder above the dividing line of the command window to run the first picture the several values ​ ​ above the dividing line several values ​ ​ of the second image. Wherein, peak_first numerical maximum peak the peak_second is the the numerical second largest peak (first sidelobe), the theta_var is the abscissa and peak_first recent about two valley distance. To find half the peak point are decimal, the array does not just equal to main lobe amplitude half points, only nearly half points, so you want to set a range, such as 0.05 or 0.05 are considered semi-peak some array, but the range of 0.05 or too small, it may be an error.)
