Learn how to build a surveillance system using WebRTC for low-latency and YOLO for object detection. This tutorial will guide you through the process of using computer vision and machine learning techniques to detect and track objects in real-time video streams. With this knowledge, you can create a surveillance system for security or other applications. However, there are challenges to consider when using cameras for object detection, including data privacy and security concerns, as well as technical limitations such as low image quality and lighting conditions. This article will teach you how to overcome some of these challenges and build a reliable surveillance system.

**Object Detection** is a computer vision task in which the goal is to detect and locate objects of interest in an image or video. The task involves identifying the position and boundaries of objects in an image, and classifying the objects into different categories. It forms a crucial part of vision recognition, alongside [image classification](/task/image-classification) and [retrieval](/task/image-retrieval). The state-of-the-art methods can be categorized into two main types: one-stage methods and two stage-methods: - One-stage methods prioritize inference speed, and example models include YOLO, SSD and RetinaNet. - Two-stage methods prioritize detection accuracy, and example models include Faster R-CNN, Mask R-CNN and Cascade R-CNN. The most popular benchmark is the MSCOCO dataset. Models are typically evaluated according to a Mean Average Precision metric.

An Introduction to Object Detection with YoloV3 for beginners
Object Detection using Yolo V3 and OpenCV .
The highest accuracy object detectors to date are based on a two-stage approach popularized by R-CNN, where a classifier is applied to a sparse set of candidate object locations. In contrast, one-stage detectors that are applied over a regular, dense sampling of possible object locations have the potential to be faster and simpler, but have trailed the accuracy of two-stage detectors thus far. In this paper, we investigate why this is the case. We discover that the extreme foreground-background class imbalance encountered during training of dense detectors is the central cause. We propose to address this class imbalance by reshaping the standard cross entropy loss such that it down-weights the loss assigned to well-classified examples. Our novel Focal Loss focuses training on a sparse set of hard examples and prevents the vast number of easy negatives from overwhelming the detector during training. To evaluate the effectiveness of our loss, we design and train a simple dense detector we call RetinaNet. Our results show that when trained with the focal loss, RetinaNet is able to match the speed of previous one-stage detectors while surpassing the accuracy of all existing state-of-the-art two-stage detectors.
