Abstract
The invention provides a photo processing method based on a digital image. The method comprises the steps of 1) providing an electronic photo; 2) adjusting and setting the background of the photo, replacing the background by using a required background picture and performing peripheral color matching adjustment processing to the photo and the background picture; 3) filtering the processed image; 4) extracting all color types contained in the filtered image, performing clustering analysis to the colors and clustering the colors into N types according to requirements; 5) performing color matching to the colors after clustering; 6) making a judgment; 7) processing the image in an electronic format into a new electronic format file with M colors and numbering according to the colors; and 8) saving the image, printing the image and performing water prevention, pressing and mounting treatment. Since the photo processing method based on the digital image adopts color-based and block-based comprehensive processing, the processed photo is enabled to be clear and vivid and has an artistic effect, the operation is simple to perform and the cost is low.
Description
Technical field
The present invention relates to the digital image processing techniques field, particularly a kind of photo processing method based on digital picture.
Background technology
Traditional photography photo is only that camera lens objectively responds a kind of of captured object, has reflected faithfully just that from effect desirable situation about requiring often appears not reaching in object, effect aspect, and has been difficult to abundant graphics art grade.
Processing to digital picture in prior art has a variety of methods, for example adopt computer software to process, perhaps adopt computing machine to add manually-operated mode and carry out certain processing, thereby reach needed effect, but waste time and energy, cost is higher, and, for the higher photo disposal of difficulty, is difficult to reach needed effect requirements.
Summary of the invention
The present invention proposes a kind of photo processing method based on digital picture, adopts color separation and piecemeal overall treatment, makes that photo after processing is clear true to nature and have an artistic effect, simple to operate, cost is low.The technical solution adopted in the present invention specifically is achieved in that
The invention provides a kind of photo processing method based on digital picture, it comprises step:
1) the papery photo is converted into electronic photo by scanning or digital photographing, electronic photo perhaps directly is provided;
2) the comparison film background is adjusted setting, is replaced by the background frame that needs, and comparison film carries out surrounding color-match adjustment processing with background frame;
3) image after above-mentioned processing is carried out filtering;
4) the institute's colored kind that comprises in above-mentioned filtered image is extracted, and these colors are carried out cluster analysis, as requested color is aggregated into N classification;
5) after polymerization, color is carried out match colors, measure the color spacing in HSV color attribute pattern, carry out color separation processing;
6) whether color is met the demands and judges, if do not meet and return to step 4) the middle cluster centre quantity of adjusting, adjust coupling;
7) image of following electronic format is processed into the new electronic format file with M kind color, and the zone of different colours in the electronic format file of this M kind color is numbered by color, same color region numbering is identical, have lines between regions of different colours, the same color zone does not have overlapping, formation is with the piecemeal block diagram of color code, and processing is revised and adjusted to artificial or software again to the piecemeal block diagram as required, perhaps colors in;
8) preserve image and print or print, carry out as required water-proofing treatment and the compacting mounting is processed.
Preferably, the image pixel that obtains of described scanning is greater than 6000*6000.
Preferably, the filtering in described step 3) is to adopt medium filtering on three passages of the RGB of image.
Preferably, the span of described M is between 25-75.
Photo processing method based on digital picture of the present invention, adopt color separation and piecemeal overall treatment, makes that photo after processing is clear true to nature and have an artistic effect, simple to operate, cost is low.
Description of drawings
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 above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, it will be more clear making above-mentioned and other purpose of the present invention, Characteristics and advantages.Reference numeral identical in whole accompanying drawings is indicated identical part.Deliberately do not draw in proportion accompanying drawing, focus on illustrating purport of the present invention.
The photo processing method based on digital picture of the specific embodiment of the invention, it comprises step:
1) the papery photo is converted into electronic photo by scanning or digital photographing, electronic photo perhaps directly is provided;
2) the comparison film background is adjusted setting, is replaced by the background frame that needs, and comparison film carries out surrounding color-match adjustment processing with background frame;
3) image after above-mentioned processing is carried out filtering;
4) the institute's colored kind that comprises in above-mentioned filtered image is extracted, and these colors are carried out cluster analysis, as requested color is aggregated into N classification;
5) after polymerization, color is carried out match colors, measure the color spacing in HSV color attribute pattern, carry out color separation processing;
6) whether color is met the demands and judges, if do not meet and return to step 4) the middle cluster centre quantity of adjusting, adjust coupling;
7) image of following electronic format is processed into the new electronic format file with M kind color, and the zone of different colours in the electronic format file of this M kind color is numbered by color, same color region numbering is identical, have lines between regions of different colours, the same color zone does not have overlapping, formation is with the piecemeal block diagram of color code, and processing is revised and adjusted to artificial or software again to the piecemeal block diagram as required, perhaps colors in;
8) preserve image and print or print, carry out as required water-proofing treatment and the compacting mounting is processed.
In the specific embodiment of the invention, preferably, the image pixel that scanning obtains is greater than 6000*6000.Preferably, the filtering in step 3) is to adopt medium filtering on three passages of the RGB of image.Preferably, the span of M is between 25-75.
In the specific embodiment of the invention, in step 3), the image that scanning is obtained adopts on three passages of RGB big or smallly gets odd number and greater than the filter window of 9*9, carries out medium filtering.In the concrete enforcement of the present invention, the span of N between 25-35, can suitably reduce number of clusters if Clustering Effect is talked about preferably, thereby make in production run, needs the color of preparing kind quantity to reduce, and the target of value is that number of colours is more few better.In the specific embodiment of the invention, judge that color is whether qualified can judge from visual effect, equally also can adopt other proving installations to judge, adopt proving installation to judge to obtain datumization more, more accurate.Obtain final filling picture by size and the cluster centre quantity of adjusting filter window, the root-mean-square error of gained picture and original image is less than 15%.
