This class represents high-level API for classification models.
ClassificationModel allows to set params for preprocessing input image. ClassificationModel creates net from file with trained weights and config, sets preprocessing input, runs forward pass and return top-1 prediction.
| cv::dnn::ClassificationModel::ClassificationModel | ( | const String & | model, |
| const String & | config = "" |
||
| ) |
Create classification model from network represented in one of the supported formats. An order of model and config arguments does not matter.
| [in] | model | Binary file contains trained weights. |
| [in] | config | Text file contains network configuration. |
| cv::dnn::ClassificationModel::ClassificationModel | ( | const Net & | network | ) |
Create model from deep learning network.
| [in] | network | Net object. |
| std::pair<int, float> cv::dnn::ClassificationModel::classify | ( | InputArray | frame | ) |
Given the input frame, create input blob, run net and return top-1 prediction.
| [in] | frame | The input image. |
