ACM Transactions on Multimedia Computing, Communications and by James R. Wilcox

By James R. Wilcox

This unique factor includes a number of the notable paintings initially offered on the ACM Multimedia convention 2003 (ACM MM 2003). The convention acquired 255 submissions, of which forty three top of the range papers have been approved for presentation. of those papers, the Technical software Chairs invited a dozen authors to post stronger types in their papers to this designated factor. those papers went via a rigorous evaluation approach, and we're chuffed to provide 4 actually awesome papers during this specialissue. a result of hugely aggressive evaluate procedure and constrained area, many fantastic papers couldn't be authorised for this targeted factor. besides the fact that, a few of them are being forwarded for attention as destiny normal papers during this magazine.

JDBC Recipes: A Problem-Solution Approach

JDBC Recipes offers easy-to-implement, usable recommendations to difficulties in relational databases that use JDBC. it is possible for you to to combine those ideas into your web-based functions, similar to Java servlets, JavaServer Pages, and Java server-side frameworks. this useful publication helps you to lower and paste the strategies with none code alterations.

Upon activation, the sensors read their configuration file to set up the basic parameters by which they should operate, including frame rate, video quality, video size, IP address of the video aggregator, etc. While we statically define the parameters by which they operate, one can easily imagine incorporating other techniques for managing the sensors automatically. 3 Video Aggregation Software The video aggregation node is responsible for the storage and retrieval of the video data for the video sensors and the clients.

There are a number of implications for compression, however. First, the quality may be degraded for the application. Second, it may require additional computation cycles in the host to which it is connected. For the Logitech cameras that we are using, the compression ratio from the USB camera is very small so that it is not suitable for wireless network transmission, requiring the data to be decompressed and recompressed into a more network friendly format. 0. Most of the low-power embedded processors do not support either technology because the manufacturers feel that the processors are unable to fully utilize the bandwidth or would spend significant amount of its power and processing dealing with such devices.
