| | |
| | | Here you can find repository with GUI-software for marking bounded boxes of objects and generating annotation files for Yolo v2: https://github.com/AlexeyAB/Yolo_mark |
| | | |
| | | With example of: `train.txt`, `obj.names`, `obj.data`, `yolo-obj.cfg`, `air`1-6`.txt`, `bird`1-4`.txt` for 2 classes of objects (air, bird) and `train_obj.cmd` with example how to train this image-set with Yolo v2 |
| | | |
| | | ## How to use Yolo as DLL |
| | | |
| | | 1. To compile Yolo as C++ DLL-file `yolo_cpp_dll.dll` - open in MSVS2015 file `build\darknet\yolo_cpp_dll.sln`, set **x64** and **Release**, and do the: Build -> Build yolo_cpp_dll |
| | | * You should have installed **CUDA 8.0** |
| | | * To use cuDNN do: (right click on project) -> properties -> C/C++ -> Preprocessor -> Preprocessor Definitions, and add at the beginning of line: `CUDNN;` |
| | | |
| | | 2. To use Yolo as DLL-file in your C++ console application - open in MSVS2015 file `build\darknet\yolo_console_dll.sln`, set **x64** and **Release**, and do the: Build -> Build yolo_console_dll |
| | | |
| | | * you can run your console application from Windows Explorer `build\darknet\x64\yolo_console_dll.exe` |
| | | * or you can run from MSVS2015 (before this - you should copy 2 files `yolo-voc.cfg` and `yolo-voc.weights` to the directory `build\darknet\` ) |
| | | * after launching your console application and entering the image file name - you will see info for each object: |
| | | `<obj_id> <left_x> <top_y> <width> <height> <probability>` |
| | | * to use simple OpenCV-GUI you should uncomment line `//#define OPENCV` in `yolo_console_dll.cpp`-file: [link](https://github.com/AlexeyAB/darknet/blob/a6cbaeecde40f91ddc3ea09aa26a03ab5bbf8ba8/src/yolo_console_dll.cpp#L5) |

| | | public: |
| | | Detector(std::string cfg_filename, std::string weight_filename, int gpu_id = 0); |
| | | ~Detector(); |
| | | |
| | | std::vector<bbox_t> detect(std::string image_filename, float thresh = 0.2); |
| | | std::vector<bbox_t> detect(image_t img, float thresh = 0.2); |
| | | |
| | | #ifdef OPENCV |
| | | std::vector<bbox_t> detect(cv::Mat mat, float thresh = 0.2); |
| | | #endif |
| | | }; |
