Image restoration is a key research field in the digital image processing technology. Due to camera defocus, the relative movement and noise, the image quality declines. Because of the limitations of Wiener filtering method, the paper proposes a kind of improved Wiener filtering restoration method based on the partition. The method can not only enhance the edges and eliminate the noise, but also eliminate...
Three different contour features are fused for gait recognition through a score level information fusion framework. The first contour feature is procrustes mean shape (PMS) which is the compact representation of gait sequence. The other two features are proposed based on PMS. One is shape context features which utilize the shape context descriptor to depict the global distribution of sample points...
To resolve the problem that the face detection is slow and detection efficiency is low in complex background, this thesis adopts double color space for color modeling based on YCbCr color space and RGB color space, and on this basis we adopt Adaboost algorithm for face detection. Based on the research of Adaboost algorithm, this thesis proposes improvements on the Adaboost training process and detecting...
Path motion object detection based on video is a fundamental part of intelligent transportation systems, In the aspect of background extraction, this paper compared all existing theories and algorithms, aimed at specific objects (city expressways or high-speed Road), and combined with the virtual loop set method. This paper proposed an extraction and updating algorithm based on the sub-segmentations...
With the further research of nonlinear systems, we have discovered that many practical physical circuits contain chaotic phenomenon. At the same time, a number of control schemes can be used to controlled chaotic system, such as control by Ott-Grebogi-Yorke (OGY) method, control by delayed feedback control (DFC) method, control by synchronization and so on. Delayed feedback control was proposed by...
This article, to meet the current demand for individual traveling, explores the design of an embedded Web service intelligent guidance system, which takes full advantage of the insert system design technology and GIS technology, providing travelers with accompanied tourism service at any time anywhere through the Web service.
In this paper, a modern logistics vehicles and cargo tracking system is designed in view of the current demand. Making full use of embedded systems technology and mobile communications technology, this system is designed to monitor the situation of cargo and vehicles in real-time and to reply the query of the owner of cargo by SMS in active or passive mode. Practice shows that this system can efficiently...
