| | | 1. Create file `yolo-obj.cfg` with the same content as in `yolo-voc.cfg` (or copy `yolo-voc.cfg` to `yolo-obj.cfg)` and: |
|---|
| | | |
|---|
| | | * change line `classes=20` to your number of objects |
|---|
| | | * change line `filters=425` to `filters=(classes + 5)*5` (generally this depends on the `num` and `coords`, i.e. equal to `(classes + coords + 1)*num`) |
|---|
| | | * change line #224 from [`filters=125`](https://github.com/AlexeyAB/darknet/blob/master/cfg/yolo-voc.cfg#L224) to `filters=(classes + 5)*5` (generally this depends on the `num` and `coords`, i.e. equal to `(classes + coords + 1)*num`) |
|---|
| | | |
|---|
| | | For example, for 2 objects, your file `yolo-obj.cfg` should differ from `yolo-voc.cfg` in such lines: |
|---|
| | | |
|---|
| | |
|---|
| | | |
|---|
| | | 4. Put image-files (.jpg) of your objects in the directory `build\darknet\x64\data\obj\` |
|---|
| | | |
|---|
| | | 5. Create `.txt`-file for each `.jpg`-image-file - with the same name, but with `.txt`-extension, and put to file: object number and object coordinates on this image, for each object in new line: `<object-class> <x> <y> <width> <height>` |
|---|
| | | 5. Create `.txt`-file for each `.jpg`-image-file - in the same directory and with the same name, but with `.txt`-extension, and put to file: object number and object coordinates on this image, for each object in new line: `<object-class> <x> <y> <width> <height>` |
|---|
| | | |
|---|
| | | Where: |
|---|
| | | * `<object-class>` - integer number of object from `0` to `(classes-1)` |
|---|
