Abstract
The invention relates to a searching method for a regional boundary of a color block in an image. The method comprises the following steps of: taking a pixel point matrix of an entire image; classifying pixel points according to transparency values and color values of the pixels; searching boundary closed curves between different types of pixel points; finally grouping the boundary closed curves, wherein one or more boundary closed curves which belong to a communication region of the same type of pixel points to form a group to construct a polygon; and finding out the outermost boundary closed curve, wherein the polygon is the regional boundary of the color block. The invention also relates to a searching device for the regional boundary of a white block in the image and image bottoming and trapping method and system on the basis. The regional boundary of the white block in the image is additionally searched, so that the white region in the image is neglected during bottoming; color transfer trapping occurs when a normal color block meets white in the image; meanwhile, the interference of a small white region in the image is eliminated; and the trapping effect is better.
Description
Technical field
The invention belongs to technical field of image processing, be specifically related to the finding method and the device of color block zone boundary in a kind of image, and shop fixtures on this basis, trapping method and system.
Background technology
There is the method for seeking transparent, the translucent and zone of opacity in the picture of publishing picture in the prior art, and do not have the method for seeking white portion in the picture of publishing picture.Therefore, when shop fixtures, can not ignore the white portion in the image, cause the shop fixtures effect bad; Do not let look between the white portion when automatic trapping in common color lump and the image, cause register trouble.Said shop fixtures is meant layer overlay background color under all nontransparent color lumps, and effect can be better in the time of like this on being printed onto some transparent material, and transparent part need not shop fixtures, and the client need see the product of package interior.Saidly let look be meant when a color lump to constitute by a dark colored inks and a plurality of light China ink and dark colored inks and light black difference in brightness when very big; Cause significantly " color limit " for fear of cause the light color China ink to expose owing to the register trouble meeting at the color lump edge; Need be with contracting in the light China ink, Here it is lets look.As shown in Figure 1, Fig. 1 a is the original image before not dealing with, and its Smalt frame inside is divided into nontransparent image, and place, four angles is white portion, and the centre is the pink colour border circular areas, and the purple piece is common color lump.Adopt existing method that Fig. 1 a is carried out effect behind the shop fixtures shown in Fig. 1 b, wherein white portion has also been carried out shop fixtures.Adopt existing method that Fig. 1 a is fallen into effect behind the seal shown in Fig. 1 c, wherein yellow circle is lived part to let look.
The main flow process that conventional images is sought the limit algorithm is: at first round the pixel matrix of width of cloth image, according to the transparence value of pixel pixel is classified; Travel through all pixels then, seek the border (comprising translucent and opaque two-part border) of the picture of publishing picture.Because this method do not seek out the border of white portion, thereby can't ignore the white in the image when causing shop fixtures, not let look between white when falling into seal in the image and the common color lump, effect is relatively poor.
Summary of the invention
To the defective that exists in the prior art, technical problem to be solved by this invention provides the finding method and the device on white portion border in a kind of image, and a kind of effect better image shop fixtures, trapping method and system are provided on this basis.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is following:
The finding method of color block zone boundary in a kind of image may further comprise the steps:
(1) rounds the pixel matrix of width of cloth image, pixel is classified according to the transparence value and the color value of pixel;

If the alpha value be 255 and the CMYK value have at least one not to be 0, then be opaque and for non-white.
The finding method in color block zone in the aforesaid image; Preferably; Behind the boundary closed curve of seeking out between the inhomogeneity pixel, comprise that also with said boundary closed curve girth be foundation in the step (2), deletion is less than the step of the boundary closed curve of setting girth.
The finding method in color block zone in the aforesaid image, said be provided with girth on be limited to 60 pixels, be limited to 5 pixels down; Preferably, said setting girth is 3.0 * 10
-5* ImageSize, the size of said ImageSize presentation video.
A kind of image shop fixtures method may further comprise the steps:
(1) the employing said method is sought the color block zone in the picture of publishing picture;
(2) in said opaque white color piece zone, fill white, in other color block zones, fill corresponding color;
(3) all colours piece is related with said image;
(4) traversal all colours piece if this color block is the opaque white color piece zone in the image, does not then carry out shop fixtures to this region unit, otherwise this color block is carried out shop fixtures.
Like above-mentioned image shop fixtures method, preferred, in the step (3), the mode through the ID of this image of record on color block realizes the related of color block and image.
A kind of image trapping method may further comprise the steps:
(1) the employing said method is sought the color block zone in the picture of publishing picture;
(2) in said opaque white color piece zone, fill white, in other color block zones, fill corresponding color;
(3) all colours piece is related with said image;
(4) traversal all colours piece is judged the sunken India side formula between the color block in twos; If one of them color block is the opaque white color piece, then continue to judge whether another color block and opaque white color piece belong to same image, in this way, color fading and trapping does not take place then, otherwise color fading and trapping takes place; If one of them color block is not the opaque white color piece, then carry out common sunken seal.
Like above-mentioned image trapping method, preferred, in the step (3), the mode through the ID of this image of record on color block realizes the related of color block and image.
