This paper presents a new method based on digital image processing to realize the real-time automatic vehicle speed monitoring using video camera. Based on geometric optics, it first presents a simplified method to accurately map the coordinates in image domain into real-world domain. The second part is focused on the vehicle detection in digital image frames in video stream. Experiment shows it requires...
This paper presents a real-time robust algorithm to detect and accurately locate the circular objects in digital images. The algorithm consists of four steps.First the edge pixels are extracted using Canny edge detection algorithm followed by a noise removal process to remove the non-circle edge points.Afterwards, a direct least square fitting algorithm is developed to calculate radius and circle...
