这里上代码
这是matlab的代码：
function [J]=defog(img)
kenlRatio = .01;
minAtomsLight = 240;
%figure,imshow(uint8(img)), title('src');
sz=size(img);
w=sz(2);
h=sz(1);
dc = zeros(h,w);
for y=1:h
for x=1:w
dc(y,x) = min(img(y,x,:));
end
end
winodwsize = floor(max([3, w*kenlRatio, h*kenlRatio]));
dc2 = minfilt2(dc, [winodwsize,winodwsize]);
dc2(h,w)=0;
t = 255 - dc2;
t_d=double(t)/255;
A = min([minAtomsLight, max(max(dc2))]);
J = zeros(h,w,3);
img_d = double(img);
r = winodwsize*4;
eps = 10^-6;
filtered = guidedfilter_color((double(img))/255, t_d, r, eps);
t_d = filtered;
J(:,:,1) = (img_d(:,:,1) - (1-0.95*t_d)*A)./t_d;
J(:,:,2) = (img_d(:,:,2) - (1-0.95*t_d)*A)./t_d;
J(:,:,3) = (img_d(:,:,3) - (1-0.95*t_d)*A)./t_d;
J=enhancement(J);
img_d(1,3,1)
J=uint8(J);
end
这段代码已经测试过没有问题。。把它编译成了一个DLL加到了工程里
这是c#的代码：

}
private void Form1_Load(object sender, EventArgs e)
{

byte[, ,] myImage = ImageToBytes(bm);
defog.Class1 output = new defog.Class1();
MWNumericArray img = new MWNumericArray(myImage);
MWNumericArray result = (MWNumericArray)output.defog(img);
MessageBox.Show("succeed");
DisposeImage(myImage, bm);
pictureBox1.Image = bm;
}
private byte[,,] ImageToBytes(Bitmap img)
{

BitmapData imgData = img.LockBits(lockRect, ImageLockMode.ReadOnly, img.PixelFormat);
byte[,] rband = new byte[img.Height, img.Width]; // 彩色图片的R、G、B三层分别构造一个二维数组

int rowOffset = imgData.Stride - img.Width * 3;
unsafe
{
byte* imgPtr = (byte*)imgData.Scan0.ToPointer();
for (int i = 0; i < img.Height; ++i)
{

{
rband[i, j] = imgPtr[2]; // 每个像素的指针是按BGR的顺序存储的
gband[i, j] = imgPtr[1];
bband[i, j] = imgPtr[0];
imgPtr += 3; // 偏移一个像素
}
imgPtr += rowOffset; // 偏移到下一行
}
}
img.UnlockBits(imgData);
byte[, ,] myImage = new byte[img.Height, img.Width, 3];
for(int i=0;i<img.Height;i++)
{
for(int j=0;j<img.Width;j++)
{
myImage[i, j, 0] = rband[i, j];
myImage[i, j, 1] = gband[i, j];
myImage[i, j, 2] = bband[i, j];
}
}
return myImage;
}
private void DisposeImage(byte [,,] myImage,Bitmap img)
{

BitmapData imgData = img.LockBits(lockRect, ImageLockMode.ReadOnly, img.PixelFormat);
int rowOffset = imgData.Stride - img.Width * 3;
unsafe
{
byte* imgPtr = (byte*)imgData.Scan0.ToPointer();
for (int i = 0; i < img.Height; ++i)
{
for (int j = 0; j < img.Width; ++j)
{

imgPtr[1] = myImage[i, j, 1];
imgPtr[0] = myImage[i, j, 2];
imgPtr += 3; // 偏移一个像素
}
imgPtr += rowOffset; // 偏移到下一行
}
}
img.UnlockBits(imgData);
}
}
}
这段代码注释掉那部分dll调用的部分也是测试过没有问题的实在是没辙了，求大虾拯救
