Embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention, rather than limitation of the invention.It also should be noted that in order to just
Part related to the present invention rather than entire infrastructure are illustrate only in description, accompanying drawing.
Embodiment one
Fig. 1 is a kind of flow chart of the searching method for similar pictures that the embodiment of the present invention one provides, and the present embodiment can fit
For searching for the situation of similar pictures, this method can be performed by the searcher of similar pictures, and the device can use soft
The mode of part and/or hardware is realized.As shown in figure 1, this method specifically includes：
Step S110, calculate the color histogram of every width picture in Target Photo storehouse and be stored in database.
Optionally, the step may particularly include：Every width picture in Target Photo storehouse is subjected to color compressed；Calculate compression
The color histogram of every width picture afterwards；The color histogram data for the every width picture being calculated is stored in database
In file corresponding to every width picture.
Wherein, color compressed is carried out to every width picture, exemplary, the pixel value of colour picture is 0 to 255, corresponding
The species number of color point is 255 cube, colour picture is carried out into color compressed, 255 grades of pixels zoom to about 8 grades of ashes
Degree, so total face variety of color points just only have 600 kinds or so, can not only reduce amount of calculation when calculating color histogram, and
And amount of calculation when can reduce similar pictures matching primitives.Also, by the way that obtained color histogram data is preserved,
When being searched for next time, the picture for the histogram data that saved colors in picture library does not have to compute repeatedly its color histogram
Figure, further reduces amount of calculation.
Step S120, Target Photo is loaded into Target Photo storehouse, calculates the color histogram of Target Photo and be stored in
In database.
Optionally, the step may particularly include：Target Photo is loaded into Target Photo storehouse；Target Photo is subjected to color
Compression；Calculate the color histogram of the Target Photo after compressing；The color histogram data of obtained Target Photo is preserved
In database in file corresponding to Target Photo.Wherein, exemplary, user can pass through mouse or input through keyboard mesh
File is marked, by specified search engine, e.g., Baidu and Google etc., Target Photo is loaded into target figure corresponding to search engine
In valut.
Step S130, the color histogram of the color histogram of Target Photo and every width picture in Target Photo storehouse is entered
Row matching, similar pictures are shown according to matching result.
Optionally, the step may particularly include：Pre-set picture match result threshold value；By the face of obtained Target Photo
Color Histogram data are matched with the color histogram data of the every width picture preserved in database；The matching result that will be obtained
Picture recognition more than or equal to threshold value is similar pictures, and shows similar pictures.
Further, obtained matching result is more than or equal to the matching value of predetermined threshold value according to order from big to small
Arrangement, and show similar pictures corresponding to the matching value successively according to same sequence.
Wherein, the otherness of color histogram is smaller between picture, and picture match end value is bigger, and similarity is higher.Example
Property, user pre-sets matching result threshold value as 95%, obtained Target Photo and picture a in Target Photo storehouse, picture b,
Picture c, picture d matching result are respectively 92%, 98%, 95%, 97%, and picture a of the matching value less than 95% is not similar
Picture, remaining picture b, picture c, matching result is ordered as 98%, 97%, 95% from big to small corresponding to picture d, then by suitable
The similar pictures that sequence is shown are picture b, picture d, picture c.
The embodiment of the present invention calculates each picture by being compressed to every width picture in Target Photo and Target Photo storehouse
Corresponding color histogram is simultaneously preserved, and similar pictures are scanned for according to the matching result of picture color histogram, is solved existing
The problem of Similarity Measure amount that the search for having similar pictures in technology is related to is big, computation complexity is high high with searching cost, it is real
Show the effective search of similar pictures, reduced the amount of calculation and complexity of similar pictures search, and reduce searching cost.
