Abstract
The present invention discloses a histogram-based network video thumbnail extracting and mapping method. The method comprises the following specific steps: 1) determining the address of a network video thumbnail through a URL; 2) caching and downloading the network video thumbnail based on the UDP protocol; 3) extracting the color and the grayscale histogram of the network video thumbnail, and establishing a mapping of the URL; 4) storing the network video thumbnail in the integrated data center of a server; 5) precisely searching the network video thumbnail based on keywords.
Description
Technical field
The present invention relates to a kind of based on the extraction of histogrammic Internet video thumbnail and mapping method
Background technology
Web crawlers only crawls text at present, it is impossible to crawling the multimedia files such as music, picture and video, it is huge that reason is mainly multi-medium data amount；How to download transmission multimedia file；How index multi-media file；And then the multimedia file processed is retrieved.The rise having substantial amounts of multimedia file, particularly social network sites to share with multimedia the most on the internet, needs precisely to retrieve multimedia file.
Web crawlers, also referred to as Web Spider, network robot, be a program automatically extracting webpage, and it is upper and lower contained network page from the Internet, is the important component part of search engine.Web crawlers utilizes the http protocol of standard, the method traversal internet information space retrieved according to hyperlink and Web document.
Thousands of kinds of different data types are had on the Internet, the object that HTTP transmits to every kind of Web to be passed through all has stamped data format tags (common video form: the video/MP4V-ES of entitled mime type, video/mpeg, video/quicktime, video/vnd.mpegurl, video/x-msvideo) (common picture format: image/jpeg, image/gif).URL (URL) is the modal form of resource identifier.URL describes the ad-hoc location of certain resource on a particular server.Element files (METAFILE) can provide the metamessage about the page, as the description of search engine and update frequency and key word, being indexed for the key word of element.
UDP is a kind of connectionless transport layer protocol in OSI Reference Model, and it is mainly used in the transmission not requiring order of packets to arrive, and the inspection of packet transmission sequence is completed by application layer with sequence, it is provided that the simple unreliable information towards affairs transmits service.Network picture can be downloaded by UDP, because UDP has the speed advantage that TCP is too far behind to catch up.
Internet video formatted file abstract extraction based on key frame, amount of calculation is very big, and requirement of real time is difficulty with.And retrieve for Internet video thumbnail, it is based on prior art, a kind of feasible path.
The invention provides a kind of based on the extraction of histogrammic Internet video thumbnail and mapping method, can be on the premise of suitably increasing data volume, the address of Internet video thumbnail is determined by URL, udp protocol caching is utilized to download Internet video thumbnail, extract the rectangular histogram of Internet video thumbnail, set up the mapping with URL, be then stored in the integrated data center of server, in order to Internet video thumbnail is precisely retrieved.
Summary of the invention
It is an object of the invention to provide a kind of based on the extraction of histogrammic Internet video thumbnail and mapping method.The present invention includes following characteristics:
Inventive technique scheme
A kind of based on the extraction of histogrammic Internet video thumbnail and mapping method, it specifically comprises the following steps that
1) address of Internet video thumbnail is determined by URL；
2) udp protocol caching is utilized to download Internet video thumbnail；
3) extract color and the gray scale histogram of Internet video thumbnail, and set up the mapping with URL；
4) the integrated data center of server it is then stored in；
5) to Internet video thumbnail, to carry out the accurate retrieval on the basis of key word.
Accompanying drawing explanation
Fig. 1 is to extract based on histogrammic Internet video thumbnail and map flow chart.
Detailed description of the invention
This based on the extraction of histogrammic Internet video thumbnail and mapping method, comprise the steps:
1) address of Internet video thumbnail is determined by URL；
2) udp protocol caching is utilized to download Internet video thumbnail；
3) extract color and the gray scale histogram of Internet video thumbnail, and set up the mapping with URL；
4) the integrated data center of server it is then stored in；
5) to Internet video thumbnail, to carry out the accurate retrieval on the basis of key word.
