As urban road intersections are prone to traffic congestion and traffic accidents, monitoring the crossing of vehicles and predicting the state is needed to reduce traffic congestion, regulate driver behavior and prevent accidents. Background subtraction and mean shift tracking are used to track vehicles. The whole monitoring process is as following. Firstly, secondary selected strategy is used to...
This paper presents a method to solve the correspondence problem in matching the stereo image using Sum of Absolute Differences (SAD) algorithm. The computer vision application in this paper is using an autonomous vehicle which has a stereo pair on top of it. The estimation of range is using curve fitting tool (cftool) for each detected object or obstacles. This tool is provided by Matlab software...
Measuring a vehicle's speed using a video image is an important technique in an intelligent transportation system. This paper presents a hardware implemented vehicle speed measurement (VSM) system. The operation of the system consists of three steps. First, we remove vehicles from a series of captured images to create a background. To do this, we introduce a simplified exclusion algorithm optimized...
This paper presents a practical Farsi license plate recognition system that can process images at high accuracy rates for real-time applications. This system is designed to exhibit the requirements of performance, computational speed, for vehicle surveillance applications, such as stolen car detection systems and traffic monitoring. These requirements are satisfied by adopting a hierarchy serial framework...
The process of the alternative functioning of the mobile phones shall be detailed keeping in mind that these devices have less memory and less computing capacity. A simple background subtraction algorithm process may be used, that projects a moving object in consideration to be in the current view, when the subtraction of the current captured image and the background reaches a certain threshold. We...
In this paper, we propose a velocity sensor for agricultural vehicles by sensing ground motion with robust image matching algorithm called Orientation Code Matching (OCM). The sensor performs velocity measurement with high accuracy and robustness without error by slipping in the fields. The algorithm of OCM is implemented on a Field Programmable Gate Array (FPGA) to perform real-time image matching...
The automated vehicle recognition is of great importance today in intelligent transportation systems. In the process of the feature extraction of vehicle recognition system, the edge vector must be extracted first. However, there are many regions in an image, and it is difficult to extract the edge vectors of the regions of the image. Therefore a novel edge tracing method based on scan-line of image...
This paper proposed methods for motorcycle and license plate detection using fixed-size vertical projection and multi-part mean analysis. The method consisted of two parts: a motorcycle detection and a license plate detection. Fixed-size vertical projection and neural network were used in the motorcycle detection process. Vertical and horizontal scanning was used to extract features for the neural...
