下面我的图像SHADING算法和5x5滤波的C#代码：

if (mImage == null)
            {
   
   
                MessageBox.Show("Please open or snap an image first.");
                return;
            }
            if (mRectangle.Width == 0)
            {
   
   
                MessageBox.Show("Please add a rectangele area first.");
                return;
            }
            //----------------------------------------------------------------------
            // 将源图像内存区域锁定
            Rectangle rect = new Rectangle(0, 0, mImage.Width, mImage.Height);
            BitmapData bmpData = mImage.LockBits(rect, ImageLockMode.ReadOnly, PixelFormat.Format8bppIndexed);


            // 获取图像参数
            int width = bmpData.Width;
            int height = bmpData.Height;
            int stride = bmpData.Stride;                // 扫描线的宽度,比实际图片要大 (RGB用)
            //int offset = stride - width * 3;            // 显示宽度与扫描线宽度的间隙  (RGB用)
            IntPtr ptr = bmpData.Scan0;                   // 获取bmpData的内存起始位置的指针
            int scanBytesLength = stride * height;     // 用stride宽度，表示这是内存区域的大小 (RGB用)


            int mBigRectangle = mRectangle.Width * mRectangle.Height;
            iCellGrayValue = new double[mBigRectangle];
            ClassCommon.iCellGrayShadingRate = new double[mBigRectangle];
            ClassCommon.iCellGrayShadingRateFinal = new double[mBigRectangle];

            int mSmallRectangle = mRectMean.Width * mRectMean.Height;
            iCellGrayValueOfSmall = new double[mSmallRectangle];


            int posScan = 0;
            int ordinal = 0;
            byte[] curGrayValue = new byte[scanBytesLength];  // 为目标数组分配内存
            Marshal.Copy(ptr, curGrayValue, 0, scanBytesLength);  // 将图像数据拷贝到rgbValues中  ==
