Object detection is an important task in sports analysis, particularly in badminton, where the high-speed motion of the shuttlecock can make it challenging to detect. Here, we suggest a badminton high-speed object detection system using YOLO, a real-time object detection model. Our system is trained on a dataset of badminton images and videos, along with corresponding object annotations. The performance of our system is evaluated using several metrics, including mean average precision, precision, recall, F1-score, and speed. The results show that our system can achieve high accuracy and real-time performance, making it suitable for use in badminton analysis applications. Our system can be used to detect and track the shuttlecock in real-time, providing valuable insights into the game, such as the speed and trajectory of the shuttlecock, which can be used to improve the performance of players and coaches.

Excerpt from the Book
Convolutional Neural Network Architecture
A Convolutional neural network (CNN) is a kind of artificial neural network that is generally utilized in image and video recognition undertakings. CNNs are intended to handle information with a grid-like topology, such as an image. They are motivated by the organization of the visual cortex in animals, which is made from small, locally connected processing regions, called receptive fields.
CNNs are made from a few layers, including convolutional layers, pooling layers, and fully connected layers. The convolutional layers apply a bunch of filters to the input picture, making a component map that is utilized to distinguish explicit highlights in the image. The pooling layers are used to lessen the spatial dimensions of the component map while keeping up with the significant highlights. The fully connected layers are utilized to perform grouping on the component map.
CNNs are able to automatically and adaptively learn spatial hierarchies of features from input images and use them to classify objects and scenes. Due to their capacity to gain rich feature portrayals directly from image data, they have turned into the go-to method for different PC vision tasks, for example, image classification, object detection, semantic segmentation, and numerous other computer vision-related tasks.
