Welcome to the ultimate guide on harnessing the power of AI to create highlight videos from basketball games! In this tutorial, we will walk you through setting up and using the AI Basketball Games Video Editor, an innovative tool built with PyTorch YOLOv4 object detection. Let’s dribble our way through the steps!

1. Setting Up Your Environment

• Clone the Repository:

  First, make sure you have git installed, then clone the project:

  git clone https://github.com/OwlTing/AI_basketball_games_video_editor.git

• Create a Virtual Environment:

  Using conda, set up a virtual environment for Python 3.6:

  conda create --name py36_env python=3.6
  conda activate py36_env

• Install Required Dependencies:

  Ensure you have the following necessary packages:

  • Debian 10
  • python 3.6
  • numpy
  • pandas
  • tqdm
  • cv2
  • pytorch 1.3.0

  Refer to the official PyTorch installation guide for details.

2. Downloading Weights and Necessary Files

• Download YOLOv4 Weights:

  You’ll need the YOLOv4 weights for detecting basketball shots. Create a directory called pytorch_YOLOv4/weights and download the yolov4-basketball.weights file into it.

• Download TensorRT Weights (optional):

  If you wish to use TensorRT for faster processing, download the yolov4-basketball.trt file and place it in the same directory.

3. Using the AI Basketball Games Video Editor

Preparation Steps

• Prepare Your Video:

  Download the basketball video you wish to edit and place it in the dataset directory.

• Create Output Folder:

  You’ll need an output folder for your results:

  mkdir result

Running the Editor

To generate your highlight video, run the following command:

python video_editor.py --video_path dataset/basketball_demo.mp4 --output_path result --output_video_name out_demo.mp4

This command will create a highlight video named out_demo.mp4 in the result folder, along with an object log file.

Optional Features

Here are some customizable options:

• –inference_size: Choose the input size for your video frames, for example, (1184, 1184).
• –output_mode: Select how you want the output video to display content (options include full, basketball, shot, etc.).

4. Troubleshooting Tips

Even the best players can encounter difficulties. Here are some troubleshooting tips if you run into issues:

• If you receive errors during installation, ensure your packages are compatible with Python 3.6 and refer to the TensorRT installation guide for additional help.
• If the video isn’t processing as expected, check the file paths for your video and weight files. They must be correct and accessible.

Understanding the Code: An Analogy

Imagine you are a basketball coach. The AI Basketball Editor acts like your sharpest assistant. When you provide it with a recording of the game (the original video), it systematically looks for all the key plays (basketball highlights) and compresses them into a neat summary (highlight video). It skillfully discerns which moments are crucial (shot frame indices) and slices them out to create a cohesive narrative (the final video). This whole process is powered by an advanced training model (YOLOv4), akin to a coach knowing exactly when to call the best plays based on their understanding of the game.

Get the Ball Rolling!

Now that you have all the necessary instructions right at your fingertips, it’s time to make your basketball highlight videos shine. Happy editing!
