In depth-image-based-rendering (DIBR), the quality of the synthesized virtual view depends on that of the depth maps in the reference views. In this paper, we develop a framework to estimate the distortion of the synthesized view when a simplified two-step warping algorithm is used and when there are random errors in the reference depth maps. A graph-based method is developed to obtain the depth and...
According to the poor effect of current aircraft airborne equipment, a method based on the Neural Network and Dempster-Shafer evidence theory information fusion is put forward. As the important aircraft airborne equipment, the aero-engine, whose lubrication system works properly or not, directly affect the operation of the aero-engine condition. This paper will study on the condition monitoring of...
A potential application of BCI is the way of prosthesis control, while the traditional ways are not appropriate for those who got the high SCI (Spinal Cord Injury). In this paper, considering the practicality of BCI based prosthesis control, especially the avoidance of appended devices, the spontaneous EEG of motor imagery was used as the control signals. The motor imagery is limited in pattern variety,...
Hyperspectral imagery offers an effective way to automatically mapping of surface sediment types in the intertidal flat. The objective of this study is to determine the possibility of mapping sediment types in the southern Sheyang River mouth, Jiangsu Province from Hyperion satellite data with linear spectral unmixing method. Results indicate that the mapping was achieved at an overall accuracy of...
Automatic location of acupuncture-point is an available way to the characterization of Chinese Medicine. In this paper, the content of infrared thermal image is investigated to mine the automatic location of facial acupuncture-point by the image processing technology. Since user's work is not involved in the location of acupuncture-point, the characterization of facial diagnosis can be greatly improved,...
For the problem of poor control precision of high-speed solenoid valves which are widely used in aero-engine control systems, a fuzzy-PID control system based on Soc single-chip is designed in this paper by using fuzzy self-tuning of PID parameters control algorithm. Because the Soc single-chip can control the output flow of high-speed solenoid valve very well by its PWM function, the monitoring system...
Human detection has always been an important part of computer vision but many implementations lack the real-time performance that real world applications require. This paper presents a real-time implementation of human detection in video using the state-of-the-art histograms of oriented gradients method. Each image in the video sequence is tested at multiple scales using a sliding window. Histograms...
Inertial measurement unit (IMU), consisted of three mutually-perpendicular ring laser gyros (RLG) and three accelerometers, is an important part of RLG-based strap-down inertial navigation systems (SINS). RLG provides measurement of change in vehicle attitude or its turn rate with respect to inertial space. Accelerometer provides measurement of specific force. These measurements provided by gyros...
