Question

求大神把以下代码转为ios类型代码

privatestring SurfFeatureDetect()
{
//获取参数
bool getDescriptors = cbSurfGetDescriptors.Checked;
MCvSURFParams surfParam =new MCvSURFParams();
surfParam.extended=rbSurfBasicDescriptor.Checked ?0 : 1;
surfParam.hessianThreshold=double.Parse(txtSurfHessianThreshold.Text);
surfParam.nOctaves=int.Parse(txtSurfNumberOfOctaves.Text);
surfParam.nOctaveLayers=int.Parse(txtSurfNumberOfOctaveLayers.Text);
//计算
SURFFeature[] features =null;
MKeyPoint[] keyPoints =null;
Stopwatch sw =new Stopwatch();
sw.Start();
if (getDescriptors)
features = imageSourceGrayscale.ExtractSURF(ref surfParam);
else
keyPoints = surfParam.DetectKeyPoints(imageSourceGrayscale, null);
sw.Stop();
//显示
bool showDetail = cbSurfShowDetail.Checked;
Image<Bgr, Byte> imageResult = imageSourceGrayscale.Convert<Bgr, Byte>();
StringBuilder sbResult =new StringBuilder();
int idx =0;
if (getDescriptors)
{
foreach (SURFFeature feature in features)
{
imageResult.Draw(new CircleF(feature.Point.pt, 5), new Bgr(255d, 0d, 0d), 2);
if (showDetail)
{
sbResult.AppendFormat("第{0}点（坐标：{1}，尺寸：{2}，方向：{3}°，hessian值：{4}，拉普拉斯标志：{5}，描述：[",

}
else

//释放资源

//返回
