# PySimpleGUI openCV YOLO Deep Learning
|
||||
|
||||
To save room in the PySimpleGUI Repo, this project has been moved to its own repo on GitHub
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
## Running the Demos
|
||||
|
||||
You will need to pip install openCV and PySimpleGUI
|
||||
```
|
||||
pip install opencv-python
|
||||
pip install pysimplegui
|
||||
```
|
||||
|
||||
Run any of the .py files in the top level directory:
|
||||
```
|
||||
yolo.py - single image processing
|
||||
yolo_video.py Video display
|
||||
yolo_video_with_webcam.py - webcam or file source. Option to write to hard drive
|
||||
```
|
||||
And you'll need the training data. It's 242 MB and too large for GitHub:

||||

|
||||

||||
## Learn More
|
||||
|
||||
This code has an article associated with it that will step you through the code (minus GUI part).
