简单的图像融合

含笑：不上上次的图像融合，一个小程序。

界面用了PictureBox1和PictureBox2存载两幅原始图片，用PictureBox3显示融合后的图片。

效果：





主要算法代码如下，有兴趣的同学自己研究去。

首先添加命名空间：using System.Drawing.Imaging;

int BPP = 4;

Bitmap bgImage = new Bitmap(pictureBox1.BackgroundImage);

Bitmap fgImage = new Bitmap(pictureBox2.BackgroundImage);

int Width = bgImage.Width;

int Height = bgImage.Height;

BitmapData bgData = bgImage.LockBits(new Rectangle(0, 0, Width, Height), ImageLockMode.ReadWrite, PixelFormat.Format32bppArgb);

BitmapData fgData = fgImage.LockBits(new Rectangle(0, 0, Width, Height), ImageLockMode.ReadWrite, PixelFormat.Format32bppArgb);

unsafe

{

byte* bg = (byte*)bgData.Scan0;

byte* fg = (byte*)fgData.Scan0;

int offset = bgData.Stride - Width * 4;

for (int y = 0; y < Height; y++)

{

for (int x = 0; x < Width; x++)

{

if (fg[3] != 0)

{

bg[0] = (byte)((fg[0] - bg[0]) * 150 / 255 + bg[0]);

bg[1] = (byte)((fg[1] - bg[1]) * 150/ 255 + bg[1]);

bg[2] = (byte)((fg[2] - bg[2]) * 150 / 255 + bg[2]);

}

bg += BPP;

fg += BPP;

}//X

bg += offset;

fg += offset;

}//Y

bgImage.UnlockBits(bgData);

fgImage.UnlockBits(fgData);

Bitmap dstImage = (Bitmap)bgImage.Clone();

bgImage.Dispose();

fgImage.Dispose();

pictureBox3.BackgroundImage = dstImage;

}

}

}
