Dan Petro 39ca494295 More prediction unit tests 2019-07-26 15:51:42 -07:00
Dan Petro 7db3c60ed8 Added some unit tests
- All prediction tests
2019-07-26 15:12:25 -07:00
Dan Petro 9023c0ee9f Minor readme changes 2019-07-17 10:37:31 -07:00
Dan Petro 03ebc806fd Added threshold option to heatmap generation 2019-07-17 10:36:29 -07:00
Dan Petro 9cff8c45a3 Changed images directory to "images/" from "images_224x224/"
- You can have whatever size you want
2019-07-02 14:12:16 -07:00
Dan Petro 3bdaf3cd1d Moved back to MobileNet v1
- v2 had bad performance. Don't know why yet.

To eyeball some screenshots, just run the "predict" mode:
```
eyeballer --weights YOUR_WEIGHTS.h5 predict YOUR_FILE.png
eyeballer.py --weights YOUR_WEIGHTS.h5 predict YOUR_FILE.png
```
Or for a whole directory of files:
```
eyeballer --weights YOUR_WEIGHTS.h5 predict PATH_TO/YOUR_FILES/
eyeballer.py --weights YOUR_WEIGHTS.h5 predict PATH_TO/YOUR_FILES/
```
## Training
To train a new model, run:
```
eyeballer train
eyeballer.py train
```
You'll want a machine with a good GPU for this to run in a reasonable amount of time. Setting that up is outside the scope of this readme, however.

You just trained a new model, cool! Let's see how well it performs against some images it's never seen before, across a variety of metrics:
```
eyeballer --weights YOUR_WEIGHTS.h5 evaluate
eyeballer.py --weights YOUR_WEIGHTS.h5 evaluate
