with the ability to recognize individual "objects" within an image, which paves the way to ultimately tracking those objects through game play.'''

desc = '''Hockey Breed detector v2 uses a state of the art (circa 2023) computer vision approach.

I used the same training images as the first version of the Hockey Breeds model, but change the ML algorithm to use YOLO object detection (YOLO v8).
The output will be a set of hockey objects (defined by "bounding boxes") with labels for any hockey image uploaded.

**Object List**:
1. net
1. stick
1. puck
1. skater
1. goalie
1. referee
