3) filtering is carried out to the image after above-mentioned process;
4) the institute's colored kind comprised in above-mentioned filtered image is extracted, and cluster analysis is carried out to these colors, as requested color is aggregated into N number of classification;
5) after polymerization, match colors is carried out to color, in HSV color attribute pattern, measure color spacing, carry out color separation processing;
6) whether color met the demands judge, if do not meet, return to step 4) in adjustment cluster centre quantity, carry out adjustment and mate;
7) the new electronic format file of M kind color is then become to have to the image procossing of electronic format, and the region of different colours in the electronic format file of this M kind color is numbered by color, same color region numbering is identical, between regions of different colours, there are lines, same color region does not have overlap, form the blocking diagram with color code, artificial or software is again revised blocking diagram and adjusts process as required, or colors in;
8) preserve image and carry out printing or printing, carrying out water-proofing treatment and compacting mounting process as required.
Preferably, the image pixel that described scanning obtains is greater than 6000*6000.

Preferably, the span of described M is between 25-75.
Photo processing method based on digital picture of the present invention, adopts color separation and piecemeal overall treatment, makes the apparent after processing true to nature and has artistic effect, simple to operate, cost is low.
Accompanying drawing explanation
Fig. 1 is the process flow diagram of the photo processing method based on digital picture of the specific embodiment of the invention.
Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing, make above-mentioned and other object of the present invention, Characteristics and advantages will be more clear.Reference numeral identical in whole accompanying drawing indicates identical part.Deliberately do not draw accompanying drawing in proportion, focus on purport of the present invention is shown.
The photo processing method based on digital picture of the specific embodiment of the invention, it comprises step:
1) papery photo is converted into electronic photo by scanning or digital photographing, or directly provides electronic photo;
2) comparison film background is carried out adjustment and is arranged, and be replaced by the background frame of needs, and comparison film and background frame carries out the adjustment of surrounding color-match processes;
3) filtering is carried out to the image after above-mentioned process;
4) the institute's colored kind comprised in above-mentioned filtered image is extracted, and cluster analysis is carried out to these colors, as requested color is aggregated into N number of classification;
5) after polymerization, match colors is carried out to color, in HSV color attribute pattern, measure color spacing, carry out color separation processing;
6) whether color met the demands judge, if do not meet, return to step 4) in adjustment cluster centre quantity, carry out adjustment and mate;
7) the new electronic format file of M kind color is then become to have to the image procossing of electronic format, and the region of different colours in the electronic format file of this M kind color is numbered by color, same color region numbering is identical, between regions of different colours, there are lines, same color region does not have overlap, form the blocking diagram with color code, artificial or software is again revised blocking diagram and adjusts process as required, or colors in;
8) preserve image and carry out printing or printing, carrying out water-proofing treatment and compacting mounting process as required.
In the specific embodiment of the invention, preferably, scan the image pixel obtained and be greater than 6000*6000.Preferably, the filtering in step 3) adopts medium filtering on RGB tri-passages of image.Preferably, the span of M is between 25-75.
In the specific embodiment of the invention, in step 3), the image obtained scanning adopts size to get odd number on RGB tri-passages and the filter window being greater than 9*9 carries out medium filtering.During the present invention specifically implements, the span of N is between 25-35, if Clustering Effect is talked about preferably suitably can reduce number of clusters, thus the color kind quantity needing in production run to prepare is reduced, the target of value is that number of colours is more few better.In the specific embodiment of the invention, judging that whether color is qualified can judge from visual effect, and other proving installations equally also can be adopted to judge, adopts proving installation to judge to obtain datumization more, more accurately.Obtain final filling picture by the size and cluster centre quantity that adjust filter window, the root-mean-square error of gained picture and original image is less than 15%.
