Embodiment
The process flow diagram of the method that Fig. 1 realizes for the present invention retrieving, as shown in Figure 1, may further comprise the steps:
Step 100: the colouring information that obtains the picture that needs retrieval.
This step comprises: extract the picture of needs retrieval, the picture after extracting is carried out sharpening handle, calculate crucial colouring information.The concrete realization comprises:
At first, to the picture processing that unitizes.For the ease of extracting picture, can all pictures be fixed to the size of 640*480.That is to say, enlarge processing for little picture; Dwindle processing for big picture.Concrete implementation method can be used prior art, is those skilled in the art's conventional techniques means, repeats no more here;
Then, picture is carried out sharpening and the processing of crucial Object Extraction, promptly use sharpening technique to look for the edge of crucial object;
At last, the pixel of crucial interior of articles is directly extracted rgb value.Color extracting is very simple technology, and windows draws gets the look device and just can extract color, and specifically realization is repeated no more here.
Step 101: calculate corresponding picture fingerprint according to the colouring information that obtains.
The implication of fingerprint (search) is a corresponding unique numeral of a group file.According to different algorithms, what these files can be identical (the md5 sign indicating number of file that is to say the content and the length of two files, and attribute is all identical, and fingerprint is just identical) also can be (such as the fingerprint of Webpage search) of being correlated with.
The concrete realization of this step comprises: the picture fingerprint that generates according to the rgb value of the picture that extracts.
At first, through rgb value is carried out the obfuscation technical finesse.Such as: very approaching in two colors, think such as naked eyes the same, but find it is different during Computer Processing, at this moment, the similarity of these two colors is very high.In order to let the high color of two such similarities generate identical picture fingerprint, can approx close color be corresponded to a value, such as RGB={255,0,0} representes it is red; RGB={253,0,0} representes it is red, but the two is unequal very similar; Arrive such as respectively the two being blured: RGB={255,0,0}=＞RGB={16,0; 0}, RGB={253,0,0}=＞RGB={16; 0,0}, just with the two R value divided by 8 round numbers, the color that obtains like this can be described as the color after the obfuscation;
Then, the color of the crucial object after all obfuscations is generated a fingerprint, promptly fingerprint=＞set of litura, and litura={ color after the positional information+fuzzy }.
Step 102: according to the corresponding pictorial information of the picture fingerprint search that calculates to obtain retrieving information.In this step, index information should be the md5 sign indicating number that fingerprint generates.
The composition structural representation of the device that Fig. 2 realizes for the present invention retrieving, as shown in Figure 2, apparatus of the present invention comprise color acquisition module, fingerprint index module at least, and the search information acquisition module, wherein,
The color acquisition module is used to obtain the colouring information of the picture of needs retrieval.Here, need the picture of retrieval to be stored in the raw data base.
The fingerprint index module is used for calculating corresponding picture fingerprint according to the colouring information from the color acquisition module.The picture fingerprint that calculates can be stored in the index data base.
The search information acquisition module is used for according to the corresponding pictorial information of the picture fingerprint search that calculates to obtain retrieving information.This search information acquisition module receives and produces user's the corresponding fingerprint of search intention with patterned mode (GUI interface) through user interface.Wherein retrieval realizes through existing searcher, and searcher uses fingerprint to retrieve, and the Search Results that retrieves is passed to the user.
Through the inventive method and device, utilize the finger print information of picture, realized using picture to carry out the retrieval of the product in the network trading, satisfied user's Search Requirement better, improved the experience of user to network trading.
The composition structural representation of the embodiment of the device that Fig. 3 realizes for the present invention retrieving, as shown in Figure 3, be the synoptic diagram of the compatible existing indexing unit of retrieving through Word message of the present invention, wherein:
Raw data base is used to store the information of the needs retrieval of user's input, comprises Word message, and/or pictorial information.
Index data base is used to store the index information according to the information acquisition of the needs retrieval of user's input, comprises text index information, and/or the index information of picture fingerprint.
Index is exactly the index module in the search engine, and the retrieval request that is used for relative users is carried out the inquiry of image content fast at index data base according to fingerprint.
Searcher, the index information that is used for utilizing index data base to store is retrieved, and the Search Results that retrieves is passed to the user.What be connected with searcher has two user interfaces, and one is the existing text user interface that is used to receive and dispatch the index relevant with Word message; Another is the fingerprint user interface with the corresponding fingerprint of patterned mode (GUI interface) reception and generation user's search intention.
The color acquisition module is used to obtain the colouring information of the picture of needs retrieval.Here, need the picture of retrieval to be stored in the raw data base.
The fingerprint index module is used for calculating corresponding picture fingerprint according to the colouring information from the color acquisition module.
The above is merely preferred embodiment of the present invention, is not to be used to limit protection scope of the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to replacement and improvement etc., all should be included within protection scope of the present invention.
