A new technique of scanned image restoration is proposed to save a large amount of important old documents. Firstly, by using a high definition scanner, these obsolete documents are scanned page by page to get the HD images. Secondly, different processing techniques are adopted, including removing black holes, deepening handwriting, denoising, etc., so as to make the contents of the files clearer...
With the rapid development of wireless technology, WLAN(Wireless Local Area Network) technology is gradually integrate and replace the LAN technology, has played an important role in promoting the development of campus information technology, will be an important component in campus network. Build a stable, safe, efficient, convenient wireless campus network has become the inevitable trend of development...
3D hand gesture tracking is one of the key problems in human-computer interface design and has attracted increasing attention as an alternative way to traditional input devices, such as mouses and keyboards. Generally speaking, a human hand, as a typical articulated structure, has 15 joints and high dimensionality with 26DOFs, which makes it very difficult for real time tracking. A novel approach...
A novel sampling method is put forward in this paper. Firstly, under specific human-computer conditions, both cognitive psychology features of operators and motion features of the operators' hands are studied, upon which a basic assumption is made. Then, a sampling algorithm is put forward. Finally, in order to demonstrate validity and performance of our algorithm, a great deal of experiments is completed...
