In this paper we describe the development of an experimental continuous authentication system which uses face recognition and the evaluation of this system. The system uses OpenCV libraries for and Local Binary Pattern as face recognizer. The performance of the system is tested on several aspects: the taxation on the CPU, different environmental conditions, how well an imposter is detected and ...

In this work we perform an extensive comparative study of approaches for mobile visual recognition by simultaneously evaluating the performance and the computational cost of state-of-the-art key-point detection, feature extraction and encoding algorithms. Every step is independently tested so that its contribution to the final computational cost can be measured. The widely used OpenCV library i...

This paper studies a low-cost computerbased 3D laser radar collection system. First, the control of actuator is realized by serial communication and the 2D image is captured from lines to surface, then denoise processing calibration is carried out by using Open CV. By using Irrlicht3D engine, the point cloud data is to be rendered to convert the 2D images to the 3D effect. Robot’s collection on...

When humans interact with computer systems, they expect the experience to meet human standards of reactiveness, robustness and, if possible, non-intrusiveness. In order for computer vision techniques to have a significant impact in human-computer interaction, the development of efficient and robust algorithms, as well as their integration and operation as part of complex (including multi-modal)...

Automatic License Plate Recognition system is a real time embedded system which automatically recognizes the license plate of vehicles. There are many applications ranging from complex security systems to common areas and from parking admission to urban traffic control. Automatic license plate recognition (ALPR) has complex characteristics due to diverse effects such as of light and speed. Most...
