class ImageProcessing

//  ImageProcessing* ImgPtr;
    private:

    IplImage *img0, *img1;

};

编译时抛出错误'CvTrackers'在编译时尚未声明。当我在类外面声明它时，编译器没有抛出任何错误。但是当我使它成为类成员时，编译器会抛出错误。伙计们帮我解决了这个错误。

Answer 1

好的，我查看了Github上的CVBlobs.h文件，相关结构中for循环中使用的迭代器是CvTracks :: iterator。我建议尝试删除const_并查看是否有效。

错误：'CvTrackers'尚未申报
