Most of the TV manufacturers have released 3DTVs in the summer of 2010 using shutter-glasses technology. 3D video applications are becoming popular in our daily life, especially at home entertainment. Although more and more 3D movies are being made, 3D video contents are still not rich enough to satisfy the future 3D video market. There is a rising demand on new techniques for automatically converting...
Currently, most of the watermarking algorithms for H.264/AVC video coding standard are encoder-based due to their high perceptual quality. However, for the compressed video, they increase the computational burden to decode the video, embed the watermark, and then re-encode it. Obviously it is a bottleneck for real-time applications. Conventional watermarking algorithms in the bit-stream domain can...
This paper provides a novel method to access ZigBee based wireless sensor networks (WSN) from the Internet using web service approach. We designed a novel gateway between the WSN and the Internet mainly for the scenario of home and building automation. With the improvement of the traditional gateway, the users on the Internet can access the data of the sensor networks flexibly via web services. Each...
In this paper, a new integration scheme of robust and fragile for secured digital watermarking is developed and implemented. The proposed method uses symmetric encryption algorithm, error correcting code and random permutation to process the original watermark information, and then embeds it into the blue component of image in robust process. In fragile process, a session key and the red component...
Video summarization is not only the key to effective cataloging and browsing video, but also as an embedded cue to trace video object activities. In this paper, a video summarization approach based on machine learning is developed for automatic video transition prediction. Several novel features are extracted to characterize video boundary, including cut, fade in, fade out and dissolve for facilitating...
Readability is a very important factor for radio frequency identification (RFID) applications. One of the main reasons for readability degradation is field nulls (also called dead zones). In this paper, the causes of the dead zones are analyzed and simulated. Based on FSK-FM modulation, a novel RFID transceiver with enhanced readability under multipath environments is developed. The simulation results...
