OpenCV参考手册(2.4.x)声明初始化MSER的构造函数需要以下参数:

delta,min_area,max_area,max_variation,min_diversity,max_evolution,area_threshold,min_margin,edge_blur_size.

我正在处理灰度图像.参数"delta","max_variation"和"min_diversity"的用途是什么？这些参数有助于控制MSER的哪些属性？

我已经尝试了很多来找到这个的确切答案,我只能在下面的页面上找到一些信息(没有一个在告诉我这3个参数究竟是什么控制时特别有用):1.OpenCV wiki 2. Wikipedia MSER的描述 3. 关于STackOverflow的MSER问题

请帮忙!

我执行以下代码来生成字符方面的置信度值:

int main(int argc, char **argv) {

    const char *lang="eng";
    const PIX   *pixs;
     if ((pixs = pixRead(argv[1])) == NULL) {
       cout <<"Unsupported image type"<<endl;
        exit(3);
      }
    TessBaseAPI  api;
    api.SetVariable("save_blob_choices", "T");
    api.SetPageSegMode(tesseract::PSM_SINGLE_WORD  );        
    api.SetImage(pixs);
    int rc = api.Init(argv[0], lang);
    api.Recognize(NULL);
    ResultIterator* ri = api.GetIterator();
    if(ri != 0)
    {
        do
        {
            const char* symbol = ri->GetUTF8Text(RIL_SYMBOL);
            if(symbol != 0)
            {
                float conf = ri->Confidence(RIL_SYMBOL);
                cout<<"\nnext symbol: "<< symbol << " confidence: " << conf <<"\n" <<endl;

             }


            delete[] symbol;
                }    while((ri->Next(RIL_SYMBOL)));
    } …
