如何求模糊等价矩阵,MATLAB程序
Public Sub Norm_Diff(ByRef Data() As Double) Dim m As Integer, N As Integer, i As Integer, j As Integer Dim Ave As Double, s As Double N = UBound(Data, 1): m = UBound(Data, 2) 'n样品数,m变量数 For j = 1 To m Ave = 0 For i = 1 To N Ave = Ave + Data(i, j)...
matlab 图像融合后 怎么求图像的均值,标准差啊?
tempY(1:(M-1),1:N)=img(2:M,1:N);diffX=img-tempX;diffY=img-tempY;diffX(1:M,N)=0; %%% the boundery set to 0 diffY(M,1:N)=0;diffX=diffX.*diffX;diffY=diffY.*diffY;AVEGRAD=sum(sum(diffX+diffY));AVEGRAD=sqrt(AVEGRAD\/2);AVEGRAD=AVEGRAD\/((M-1)*(N-1...
怎么计算模糊一致矩阵

平均梯度的梯度公式
white210：平均梯度越大，图像层次越多，也就越清晰。其定义为：式中：F(i,j)为图像的第i行，第j列的灰度值；M、N分别为图像的总行数和总列数。单幅图像的平均梯度值计算MATLAB源程序：说明：该程序的作用是计算输入图像img的平均梯度值AVEGRAD平均梯度值可以衡量图像细节反差表达的能力，是图形融合...
