MAT类型是相同的，但我获得的“推动向量类型与函数中的矩阵类型不同＆＃x27; push_back＆＃x27; ＆quot错误

Question

我正在尝试重塑SIFT描述符矩阵，然后将其推回另一个矩阵，但我会收到此错误 pusthed向量类型与'push_back'push_back'中的矩阵类型不同。

这是我的代码：

Mat get_featuesunclustered( Mat input)
{
  if(!input.data)
    {
      cout << "Image not found !!!" << endl << endl;
    }
  
  //To store the keypoints that will be extracted by SIFT
  vector<KeyPoint> keypoints;

  //To store the SIFT descriptor of current image
  Mat descriptor;  

  //The SIFT feature extractor and descriptor
  Ptr<SIFT> detector = SIFT::create();
    
  //detect feature points and compute the descriptors for each keypoint
  detector->detectAndCompute(input, noArray(), keypoints, descriptor);

  if (descriptor.type() != CV_32F)
    {
      descriptor.convertTo(descriptor, CV_32F);
    }
  
  return descriptor;
}

int main(){
  Mat dicodescriptor,labels, feats;
  vector<Mat> dico; // dico contains images

  for(size_t y = 0; y < dico.size(); y++)
      {
         dicodescriptor = get_featuesunclustered(dico[y]);
      
         Mat f = dicodescriptor.reshape(dicodescriptor.rows * dicodescriptor.cols, 1);
         feats.push_back(f);    
      }
}

我不知道我的代码有什么问题，有人可以帮忙吗？
