And it contains the richer content, the larger the amount of file data, as thus the traditional theme keyword search technology cannot meet the needs of the way of images and audio and video files.
But with today’s the increasing number of multimedia files data network, the traditional text-based search engines increasingly inadequate the needs of users.
Traditional functions about multimedia utilization is referred to their syntactical properties: functions manipulate the temporal structure of data types such as forward and rewinding [2].
In contrast to these traditional media, multimedia files spread over the Internet can get more detailed information of media audiences: Including gender, age, income, education, occupation and other demographic data, you can also get the audience’s behavior data, including the number of visits, access time, access frequency, duration, etc.
Content feature extraction refers to find expression of the original signal of audio, to extract data that can represent the original signal.

TSA is a well established non-contacting analysis technique that provides full-field stress data over the surface of a cyclically loaded component.
Stainless steel specimens were deformed to contain 2% to 10% plastic strain in increments of 2% to provide a large range of strain data.
Tests were conducted at 5 Hz, 7.5 Hz and 10 Hz to assess the effect of the paint coating on the recorded data.
All data was collected from the same 316L specimen under the same loading conditions, and the specimen was not removed between tests.
From the study, it is clear that if very high accuracy is required, comparisons should not be made between data sets recorded under different conditions.

In the process, it is a very important significance in different industries about how to use the platform of network communication realizes classification retrieval technology of video data stream in the network.
Study on the basic ideas and processes is shown in Fig. 1: The focus of the study has two, first, because the video data flow is very large, how to reduce the load on both ends of the client and the server at the same time in the communication network.
Ease of Use Research of Communication Network System Structure The client and the server burden increasingly heavy, large video data stream was transmitted in the communications network, if simply relying on the traditional C/S Network transmission mode, certainly cannot meet the performance requirements of real-time video.
Mainly for video data information analysis, resource collection agent, client implementation user interaction with the video data representation, C/M/S mode can reduce the load on both ends of the client and the server, makes them collaborative work to improve service quality and efficiency, and through the search semantic processing object attributes to improve the retrieval performance.
And using canny reduction methods, technology through inheritance to reduce analysis of candidate region, went on to the regional group and returns the average of a series of combinations of various large enough rectangle.

Based on the data and the topography from the above Table.5 and Fig.7, the mass percent of Germanium is 89.90%, the mass percent of carbon and oxygen in the protuberance region is between the percentage composition of protuberance and matrix.
After repeated experiments we can speculate that a small quantity of oxygen in the germanium single crystal probably derived from incomplete reduction germanium dioxide and vapor mixed in the argon atmosphere.
Graphite is not inclined to mix with germanium in the sense of metallurgy, at least 108cm-3 of carbon solid solubility at the melting point of germanium, the conclusion can be extrapolated from high-temperature data acquired at earlier time [14].
Carbon and oxygen were the main electrically inactive inclusions in the germanium single crystal, carbon inclusions derived chiefly from single crystal furnace system, a small quantity of oxygen in the germanium single crystal probably derived from incomplete reduction germanium dioxide and vapor in the argon atmosphere.
