Description
Technical field
The present invention relates to network trading technology, in espespecially a kind of network trading, realize method and the device of product retrieval.
Background technology
At present, network trading mainly contains two kinds of patterns, and one is B2C pattern, namely commodity and information from enterprise directly to consumer; Another kind is C2C mode, and namely commodity and information are from consumer directly to consumer, are commonly called as " running a shop on the net ".Wherein, C2C is a kind of common trade mode, and directly actual to consumer (C2C, ConsumertoConsumer) from consumer is the dialect of ecommerce, is interindividual ecommerce.C2C is also namely between consumer.
In fast-changing internet industry, C2C trade mode is more and more subject to liking of numerous clients.User not only can buy by C2C mode the product needed in transaction net (as patting, Taobao), can also sell some products according to the demand of oneself.The problems such as wherein, patting is the third-party business safety control platform of Tengxun, and Main Function is to ensure that both parties carry out the safety of concluding the business on the net, sincere.Such as, the transaction that both parties can will discuss under line, is moved to and is concluded the business on the net by third-party transaction platform on the net; And online transaction to be more client pass through finds product required for oneself on the net in transaction, thus to conclude the business.
Under C2C pattern, before user buys product, usually need to understand some details that it wants the product bought, such as quality, color, weight, shelf-life etc.Current pats and Taobao, retrieval is all based on keyword, and such as user wants to buy a lunch box, the Word message of user's input " lunch box ", can search corresponding pictorial information, and user can select corresponding product to obtain wanted result by these pictures.
The existing product retrieval based on text description is widely used in C2C, the platforms such as B2C.This retrieval can meet the demand of more than 95%.But the special requirement of user cannot be met, the demand that such as cannot be described with word, in other words, by the result too magnanimity of text description.
Summary of the invention
In view of this, fundamental purpose of the present invention is to provide a kind of method and the device that realize product retrieval, picture can be used to retrieve, meet the Search Requirement of user better, improves user to the experience of network trading.

Fig. 3 is the composition structural representation that the present invention realizes the embodiment of the device retrieved.
Embodiment
Fig. 1 is the process flow diagram that the present invention realizes the method retrieved, and as shown in Figure 1, comprises the following steps:
Step 100: the colouring information obtaining the picture needing retrieval.
This step comprises: the picture extracting needs retrieval, carries out Edge contrast, calculate crucial colors information to the picture after extracting.Specific implementation comprises:
First, unitized process is carried out to picture.For the ease of extracting picture, all pictures can be fixed to the size of 640*480.That is, expansion process is carried out for little picture; Large picture is carried out reducing process.
Then, sharpening and critical object extraction process are carried out to picture, namely use sharpening technique to look for the edge of critical object;
Finally, to the pixel extracting directly rgb value of critical object inside.
Step 101: calculate corresponding picture fingerprint according to the colouring information obtained.
The implication of fingerprint (search) is the unique numeral of corresponding one of one group of file.According to different algorithms, these files can identical (the md5 code of file, that is content of two files and length, attribute is all identical, and fingerprint is just identical), also can be relevant (fingerprint of such as Webpage search).
The specific implementation of this step comprises: the picture fingerprint generated according to the rgb value of the picture extracted.
First, by carrying out obfuscation technical finesse to rgb value.Such as: very close in two colors, such as naked eyes are thought the same, but find it is different during computer disposal, and now, the similarity of these two colors is very high.In order to allow the high color of two such similarities generate identical picture fingerprint, can approx by required for a close Color pair value, such as RGB={255,0,0} represents it is red, RGB={253,0,0} represents it is red, but the two is unequal very similar, such as respectively the two is fuzzyly arrived: RGB={255,0,0}=>RGB={16,0,0}, RGB={253,0,0}=>RGB={16,0,0}, namely by the R value of the two divided by 8 round numbers, the color obtained like this can be described as the color after obfuscation;
Then, the color of the critical object after all obfuscations is generated a fingerprint, i.e. the set of fingerprint=> litura, and litura={ color after positional information+fuzzy }.
Step 102: according to pictorial information corresponding to the picture fingerprint search calculated to obtain retrieving information.In this step, index information should be the md5 code that fingerprint generates.
Fig. 2 is the composition structural representation that the present invention realizes the device retrieved, and as shown in Figure 2, apparatus of the present invention at least comprise color acquisition module, fingerprint index module, and search data obtaining module, wherein,
Color acquisition module, for obtaining the colouring information of the picture needing retrieval.Here, the picture of retrieval is needed can be stored in raw data base.
Fingerprint index module, for according to the colouring information from color acquisition module, calculates corresponding picture fingerprint.The picture fingerprint calculated can be stored in index data base.
Search data obtaining module, for according to pictorial information corresponding to the picture fingerprint search calculated to obtain retrieving information.This search data obtaining module to be received in patterned mode (GUI interface) by user interface and produces fingerprint corresponding to the search intention of user.Wherein retrieve and realized by existing searcher, searcher uses fingerprint to retrieve, and the Search Results retrieved is passed to user.
By the inventive method and device, utilize the finger print information of picture, achieve the retrieval using picture to carry out the product in network trading, meet the Search Requirement of user better, improve the experience of user to network trading.
Fig. 3 is the composition structural representation that the present invention realizes the embodiment of the device retrieved, and as shown in Figure 3, is the compatible existing schematic diagram being carried out the indexing unit of the present invention retrieved by Word message, wherein:
Raw data base, for storing the information of the needs retrieval of user's input, comprises Word message, and/or pictorial information.
Index data base, for storing the index information of the information acquisition of the needs retrieval according to user's input, comprises text index information, and/or the index information of picture fingerprint.
Index is exactly the index module in search engine, for the retrieval request of relative users in index data base, carries out the inquiry of image content according to fingerprint fast.
Searcher, for utilizing the index information stored in index data base to retrieve, and passes to user by the Search Results retrieved.What be connected with searcher has two user interfaces, and one is the existing textual user interface for receiving and dispatching the index relevant to Word message; Another receives in patterned mode (GUI interface) and produces the fingerprint user interface of fingerprint corresponding to the search intention of user.
Color acquisition module, for obtaining the colouring information of the picture needing retrieval.Here, the picture of retrieval is needed can be stored in raw data base.
Fingerprint index module, for according to the colouring information from color acquisition module, calculates corresponding picture fingerprint.
The above, be only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention, and all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
