# Abstract The "Short-Boundary Detection and Background Subtraction" project aims to enhance object detection and tracking in dynamic scenes by combining short-boundary detection and background subtraction techniques. Short-boundary detection focuses on identifying shorter edges or boundaries in an image, while background subtraction extracts the foreground from a static or changing background. This project explores the effectiveness of these methods in various applications, such as video surveillance and traffic monitoring. # Introduction Object detection and tracking are essential tasks in computer vision, particularly in dynamic scenes where the background may change over time. Short-boundary detection and background subtraction are two techniques that can improve the accuracy and robustness of these tasks. Short-boundary detection emphasizes shorter contours to detect fine details or objects in cluttered environments, while background subtraction isolates moving objects from the background. This project aims to combine these techniques to achieve robust object detection and tracking. # Related work Previous research has explored various methods for object detection and tracking, including edge detection, contour detection, and background subtraction. Techniques like Canny edge detection and Sobel filters have been widely used for edge detection, while Gaussian Mixture Models (GMM) and frame differencing are common approaches for background subtraction. This project builds on these existing methods by focusing on short-boundary detection and combining it with background subtraction to enhance performance. # Methodology Data Collection: The project uses video sequences or images as input, which are processed to detect objects and track their movement. Short-Boundary Detection: This step involves identifying shorter edges or boundaries in the image using edge detection techniques. The focus is on detecting fine details and objects that may be obscured in cluttered environments. Background Subtraction: A model of the background is created and subtracted from the current frame to extract the foreground. Techniques like frame differencing and GMM are used for this purpose. Combining Techniques: The results of short-boundary detection and background subtraction are combined to achieve robust object detection and tracking. Visualization: The detected objects and their boundaries are visualized to evaluate the performance of the methods. # Experiments The project conducts experiments using various video sequences and images to evaluate the effectiveness of the combined techniques. The experiments involve: Applying short-boundary detection to identify fine details and objects. Using background subtraction to isolate moving objects from the background. Combining the results to achieve robust object detection and tracking. Evaluating the performance using metrics like precision, recall, and F1-score. # Results The results of the experiments demonstrate the effectiveness of combining short-boundary detection and background subtraction for object detection and tracking. The combined approach improves the accuracy and robustness of detecting objects in dynamic scenes with changing backgrounds. # Discussion The discussion highlights the advantages and limitations of the combined approach. While the method improves object detection and tracking in cluttered environments, it may still face challenges in highly dynamic scenes with rapid background changes. Future work could explore advanced techniques like deep learning to further enhance performance. # Conclusion The "Short-Boundary Detection and Background Subtraction" project successfully demonstrates the benefits of combining these techniques for robust object detection and tracking. The methodology and experiments highlight the importance of focusing on fine details and isolating moving objects from the background. The project provides a foundation for further research and development in this area. # References Short-Boundary-Detection-and-Background-Subtraction GitHub Repository Related Work on Edge Detection and Background Subtraction # Acknowledgements The project was developed under the guidance of Dr. Agughasi Victor Ikechukwu.
