In this paper, we present a cross-platform environment in which handheld and desktop-computer users can collaborate with each other in a shared scene to accomplish physically realistic experiences during the course of interaction. In realizing the system, we: 1) exploit client/server architecture to connect user devices, where the server is responsible for maintaining and managing the virtual objects...
This paper presents an improved human detection algorithm of motion images. Differences of the two successive frames and background were calculated, then the multiplication of the two differences was obtained; from these results; we can separate the motion human object from the background image and get a motion template which included the motion information. It improved the result of human motion...
Feature matching plays an important role in many applications, including 3D reconstruction, object recognition and video understanding. Point matching has made great progress recently, while it has made little progress in the fields of line and curve matching. By computing statistics of point descriptors constructed at each edge points, this paper develops a novel method for extending point descriptors...
A new noise removal algorithm based on improved neural network, is applied to remove the impulse noise of the digital images. First of all, an improved neural network is used to detect the noise-pixels and distinguish it from noise-free pixels efficiently; Second, the noise-pixels are replaced further by the suitable pixel which has the most local similarity; Finally, the output is the combination...
Traffic accident scene processing is a significant content to traffic supervisory work. The development and application of photographic survey and the digital picture processing technology provide the powerful tool for solved this difficult problem. This article proposed applies binocular ranging to the traffic accident processes. We have priority introduced the technology of survey principle, image...
Transporting hybrid coded video over wireless channel is very challenging. Efficient coding and compression techniques are required to meet the QoS (Quality of Service) requirements of such services. H.264, the latest coding and compression standard from ITU-T, is currently dominating the field by offering a flexible architecture and compression gain of up to 50%. In H.264, intra frame prediction...
Anomaly detection is of particular interest in hyperspectral image analysis since many unknown and subtle signals which cannot be resolved by multispectral sensors can now be uncovered by hyperspectral imagers. More importantly, the signals of this type generally cannot be identified by visual assessment or prior knowledge and provide crucial and critical information for data analysis. Many anomaly...
