The development of moving object detection systems has become of great interest in the video surveillance field. Although many foreground detection methods have been proposed, the problems of incomplete object shapes and misclassified shadow regions remain. We propose a new approach by combining bit-planes representation with gray-level co-occurrence matrix (GLCM). This allows the system to exploit...
For solving the problem that the traditional system is not very accurate to the electric control system of thermal power plant, the paper designed and implemented the electric control system based on CAN field bus. The whole system adopted the CAN field bus control system. In all the key parts of the electric control system of the deployment of PTG502 pressure sensor to collect the real-time pressure...
In video surveillance, moving object detection has become one of the core techniques to understand video content. Many detection methods exist to detect objects, but cannot effectively compensate for the effect of shadows or incomplete shapes of moving objects. In this paper, we apply image bit-planes and hysteresis thresholding to compensate for the loss of spatial and temporal information. The experimental...
Traditional background modeling methods often require complicated computations and suffer from cavity problems in foreground objects. In this paper, we propose a block-based background modeling method combining multiple detection results derived from color and texture characteristics. This method can significantly alleviate the cavity problem and resist certain shadow interference. Since the proposed...
A new approach to obtain real-time positions of fiducial markers in MV treatment beam images is proposed. The MV images are firstly preprocessed to enhance contrast in the treatment field. To deal with large variations in projected marker shape, we propose a learning-based approach to detect marker locations in the enhanced MV images. We also show that marker tracking can be accomplished much more...
3D hand gesture recognition is an emerging technology as the market demands new user interfaces of electronic devices, especially for gaming, mobile devices, and home entertainment applications. We proposed a stereo matching design which is optimized for the 3D hand gesture recognition. As most of the existing 3D gesture recognition systems require customized camera devices (e.g. IR camera and IR...
In applications of the computer vision field, a vision system is usually composed of several low level and high level components, stacked on top of each other. A better design of the lower level components usually results in better accuracy of higher level functions, such as object tracking, face recognition, and surveillance. In this paper, we focus on the low level component design, background construction,...
PICOS18 is a real-time, multi-task control system kernel based on OSEK/VDX protocols. An embedded controller for semi-active suspension is designed in order to improve the response rate and realize the modularization design of the control system. The structure of embedded system is designed based on PICOS18. The whole control system is divided into 9 tasks according to the data flow method, and the...
