ImageLab 卷积运算
floatdata2d Ima, Kernel;
SetDim(Ima, 512, 512);
SetDim(Kernel, 3,3);
ucdata2d tmp1;
Load(122.bmp, R, G, B, A);
##数据类型变换uc->float
Ima=R;
##当定义Kernel矩阵的时候，所有元素都被赋予0.0
Kernel[0][1]=0.125;
Kernel[1][0]=0.125;
Kernel[1][1]=-0.5;
Kernel[1][2]=0.125;
Kernel[2][1]=0.125;
##Conv2的操作对象是float型的矩阵
Conv2(Ima,Kernel);
tmp1=Ima;
Save(122edge.bmp, "gray", tmp1, G, B, A);
