|---|
| | | * Remeber to put data/9k.tree and data/coco9k.map under the same folder of your app if you use the cpp api to build an app |
|---|
| | | * To process a list of images `image_list.txt` and save results of detection to `result.txt` use: |
|---|
| | | `darknet.exe detector test data/voc.data yolo-voc.cfg yolo-voc.weights < image_list.txt > result.txt` |
|---|
| | | * To process a list of images `data/train.txt` and save results of detection to `result.txt` use: |
|---|
| | | `darknet.exe detector test data/voc.data yolo-voc.cfg yolo-voc.weights -dont_show < data/train.txt > result.txt` |

| | | ##### For using network video-camera mjpeg-stream with any Android smartphone: |
|---|
| | |
|---|
| | | |
|---|
| | | 6. Set `batch=64` and `subdivisions=8` in the file `yolo-voc.2.0.cfg`: [link](https://github.com/AlexeyAB/darknet/blob/master/build/darknet/x64/yolo-voc.2.0.cfg#L2) |
|---|
| | | |
|---|
| | | 7. Start training by using `train_voc.cmd` or by using the command line: `darknet.exe detector train data/voc.data yolo-voc.2.0.cfg darknet19_448.conv.23` (**Note:** If you are using CPU, try `darknet_no_gpu.exe` instead of `darknet.exe`.) |
|---|
| | | 7. Start training by using `train_voc.cmd` or by using the command line: `darknet.exe detector train data/voc.data yolo-voc.2.0.cfg darknet19_448.conv.23` (**Note:** To disable Loss-Window use flag `-dont_show`. If you are using CPU, try `darknet_no_gpu.exe` instead of `darknet.exe`.) |
|---|
| | | |
|---|
| | | If required change pathes in the file `build\darknet\x64\data\voc.data` |
|---|
| | | |
|---|
| | |
|---|
| | | 8. Start training by using the command line: `darknet.exe detector train data/obj.data yolo-obj.cfg darknet19_448.conv.23` |
|---|
| | | |
|---|
| | | (file `yolo-obj_xxx.weights` will be saved to the `build\darknet\x64\backup\` for each 100 iterations) |
|---|
| | | (To disable Loss-Window use `darknet.exe detector train data/obj.data yolo-obj.cfg darknet19_448.conv.23 -dont_show`, if you train on computer without monitor like a cloud Amazaon EC2) |
|---|
| | | |
|---|
| | | 9. After training is complete - get result `yolo-obj_final.weights` from path `build\darknet\x64\backup\` |
|---|
| | | |
|---|
| | |
|---|
| | | |
|---|
| | | 1. Before training: |
|---|
| | | * set flag `random=1` in your `.cfg`-file - it will increase precision by training Yolo for different resolutions: [link]https://github.com/AlexeyAB/darknet/blob/master/cfg/yolo-voc.2.0.cfg#L244) |
|---|
| | | |
|---|
| | | |
|---|
| | | * increase network resolution in your `.cfg`-file (`height=608`, `width=608` or any value multiple of 32) - it will increase precision |
|---|
| | | |
|---|
| | | * desirable that your training dataset include images with objects at diffrent: scales, rotations, lightings, from different sides |
|---|
| | | |
|---|
| | | * desirable that your training dataset include images with objects (without labels) that you do not want to detect - negative samples |
|---|
| | | |
|---|
| | | * for training on small objects, add the parameter `small_object=1` in the last layer [region] in your cfg-file |
|---|
| | | |
|---|
| | | * for training with a large number of objects in each image, add the parameter `max=200` or higher value in the last layer [region] in your cfg-file |
|---|
| | | |
|---|
| | | * to speedup training (with decreasing detection accuracy) do Fine-Tuning instead of Transfer-Learning, set param `stopbackward=1` in one of the penultimate convolutional layers, for example here: https://github.com/AlexeyAB/darknet/blob/cad4d1618fee74471d335314cb77070fee951a42/cfg/yolo-voc.2.0.cfg#L202 |
