This document discusses real-time object detection using open computer vision. It reviews various object detection techniques like YOLO, OpenCV, and SVM. The proposed system uses YOLO as a supporting module with OpenCV for real-time object detection in a video or image. It analyzes the performance of algorithms in detecting and recognizing three construction vehicles on a scaled construction site. The paper also reviews and compares various object recognition models like R-CNN, YOLO, and SSD.
