Description: Object Detection is a critical area of computer vision that focuses on identifying and locating objects within an image or video. Unlike image classification, which assigns a single label to an entire image, object detection provides both the class of objects and their spatial coordinates in the form of bounding boxes. This dual task allows machines to understand scenes more comprehensively, making it essential for autonomous systems, surveillance, and augmented reality applications.Techniques for object detection have evolved significantly over the years. Traditional approaches relied on handcrafted features like SIFT or HOG combined with classifiers such as SVMs. Modern methods, however, primarily leverage deep learning architectures like Convolutional Neural Networks (CNNs). Two widely used deep learning-based approaches are the two-stage detectors, like Faster R-CNN, and single-stage detectors, such as YOLO and SSD, which balance detection speed and accuracy.Applications of object detection span across various domains. In autonomous driving, it helps vehicles recognize pedestrians, traffic signs, and other cars in real time. In retail, it assists in inventory management and customer behavior analysis. Surveillance systems use it to detect suspicious activities, while healthcare leverages it for tasks like tumor detection in medical images. Its versatility has made it a cornerstone technology in modern AI solutions.Challenges in object detection include dealing with occlusions, varying object scales, and diverse lighting conditions. Objects can appear in different orientations, and overlapping instances can confuse detection algorithms. Additionally, real-time detection for video streams demands significant computational resources, making optimization and model efficiency crucial for practical deployment.Evaluation Metrics for object detection are essential to measure model performance accurately. Commonly used metrics include Precision, Recall, Intersection over Union (IoU), and
