Background technology
The display effect of image, except relevant with image self, also can be subject to the impact of extraneous factor.Such as there being the barriers such as railing before image, can block parts of images, have influence on color, shape of image etc., thereby affect the display effect of integral image.
Current image processing techniques, when processing is blocked image, mainly contains two kinds of methods: a kind of is to process as much as possible obstructions chart picture, and the image that makes to be blocked can more completely show; Another kind is the demonstration of adjusting the image that is blocked, to reduce barrier, blocks the impact bringing.Because above-mentioned two kinds of methods are to process separately obstructions chart picture or the image that is blocked, or require a great deal of time and energy, or the effect of processing is undesirable.
Summary of the invention
The present invention has overcome deficiency of the prior art, provides a kind of by the optimization display packing of barrier shielded image, and obstacle figure and the figure that is blocked are carried out to overall treatment, and the figure that makes to be blocked under minimum change obtains better display effect.
In order to realize above-mentioned object, adopt following technical scheme:
By an optimization display packing for barrier shielded image, describedly by barrier shielded image, comprised be blocked figure and obstacle figure, described method comprises:
S1 is divided into obstacle figure the piece of several equal densities;
S2 is divided into several monochromatic plates by obstacle figure, and each monochromatic plate has single look;
S3 changes the color of the figure that is blocked according to obstacle figure;
S4 finely tunes lines and the edge of the figure that is blocked according to obstacle figure.
In such scheme, cut apart described in step S1 and adopt artificial cutting, Kmeans algorithm, compression algorithm or Histogram-based.
Described in step S2, divide and adopt with the following method:
Individual element point reads the color parameter of obstacle figure, contrasts the color parameter of adjacent two pixels, if difference is greater than preset value, is divided into different monochromatic plates, otherwise is divided into same monochromatic plate.
Described step S1 also comprises whether disturbance in judgement figure comprises the piece of several equal densities, directly carry out in this way next step, otherwise just carry out cutting operation, described step S2 also comprises whether disturbance in judgement figure is divided into several monochromatic plates, directly carry out in this way next step, otherwise just carry out division operation.
After step S2 completes, if the single look of monochromatic plate is assertive colours, first single look is treated to gradient color, then carries out step S3, described assertive colours is lightness in HSB pattern higher than 65% color.
The processing procedure of described gradient color comprises:
Determine the HSB mode parameter of described single look;
Color using described single look as starting point;
Select the phase advancing coloud nearside of a single look as the color of terminal;
One side of determining monochromatic plate is starting point, and its opposite side is terminal, from origin-to-destination, carries out color gradient, forms gradient color.
The phase advancing coloud nearside of described single look refers to that the form and aspect of single look constant, saturation degree reduces, lightness is lower than the color obtaining after 65%.
Step S3 adopts CIE method, according to the color of obstacle figure and density, the color change of the figure that is blocked is become to color of object, and the density of described obstacle figure refers to that obstacle figure accounts for by the ratio of barrier shielded image.
Described color of object adopts CIE method to be obtained by following formula in CIE color diagram:
The color of the color=figure that is blocked of the density of color of object * obstacle figure+(density of 1-obstacle figure) * obstacle figure.
Step S4 adopts fuzzy method, according to the shape of obstacle figure, the figure that is blocked is finely tuned, and the lines of the figure that makes to be blocked and edge penetration are to the position of closing on.
After step S4 completes, if having living space, place the figure not being blocked, the figure not being blocked is placed on and is blocked figure around.
Compared with prior art, the present invention is cut apart, is divided obstacle figure, again according to the obstacle figure after processing to the figure adjustment that is blocked, obstacle figure and the figure that is blocked are carried out to overall treatment, the figure that makes to be blocked under minimum change obtains better display effect.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Main-process stream of the present invention as shown in Figure 1, is analyzed below step by step.
(1) obstacle figure is divided into the piece of several equal densities.
In by barrier shielded image, together with obstacle figure partly overlaps with the figure that is blocked.If obstacle pattern density is unequal, not to be evenly distributed on image, some part of the figure that may cause being blocked is blocked by full wafer, and this part can not be shown out completely.
Be illustrated in figure 2 the obstacle figure of equal density, although obstacle figure is thickly dotted point, be distributed in entire image, due to equal density, the content that can't have influence on the figure that is blocked shows.Observer can be well understood to the content of the figure that is blocked.If obstacle figure concentrates on image middle part, although other parts are completely unobstructed, the part being blocked shows not out completely, also has influence on the content that observer understands demonstration.
Cut apart the method that obstacle figure can adopt simple artificial cutting, also can adopt Kmean algorithm, compression algorithm, Histogram-based etc. to be widely known by the people in computer video again.
(2) obstacle figure is divided into several monochromatic plates.
In by barrier shielded image, together with obstacle figure partly overlaps with the figure that is blocked, and before obstacle figure is positioned at the figure that is blocked in picture material, the color of obstacle figure can have influence on the actual color that observer sees the figure that is blocked.
While dividing monochromatic plate, individual element point reads the color parameter of obstacle figure, contrasts the color parameter of adjacent two pixels, if difference is greater than preset value, is divided into different monochromatic plates, otherwise is divided into same monochromatic plate.
(3) whether the color of disturbance in judgement figure is assertive colours.
If obstacle graphic color is too distinct, observer with the aid of pictures as time can easily leave look and print, thereby the color of figure is observed in impact.For example see for a long time bright-coloured green, can in eye, leave green look and print, seeing that afterwards other color relation can deduct green, also can affect eyes distinguishing other color.If so the color of obstacle figure is assertive colours, need assertive colours to adjust.
(4) assertive colours is processed into gradient color.
By revising saturation degree and the brightness in assertive colours HSB pattern, saturation degree is reduced, brightness is lower than 65%, obtain the phase advancing coloud nearside of assertive colours, using assertive colours and phase advancing coloud nearside as the color of starting point and terminal again, obstacle figure is carried out to color gradient, thereby form gradient color.
(5) change the color of the figure that is blocked.
The color of obstacle figure is different with observer's position, can observer be seen to be blocked the color of figure and actual color to produce deviation, and observer's position changes, therefore can only change according to the color of obstacle figure the color of the figure that is blocked.
As shown in Figure 3, find the color dot C of the color dot B of obstacle figure and the figure that is blocked in CIE color diagram, the color of the point on BC extended line and the color that B is ordered all can obtain the color that C is ordered with certain proportion allotment.According to the density of obstacle figure, obstacle figure accounts for the ratio of whole image, uses formula below:
The color of the color=figure that is blocked of the density of color of object * obstacle figure+(density of 1-obstacle figure) * obstacle figure
The color of the color of object point A obtaining is the color of object that the figure that is blocked changes color.According to the difference of the density of obstacle figure, color of object point is the point of diverse location on BC extended line.If the color of object calculating has been pointed out CIE color diagram region, suitably adjust obstacle figure and the color of the figure that is blocked, color of object point is fallen in the region of CIE color diagram.
(6) finely tune lines and the edge of the figure that is blocked.
Be blocked some lines or the edge of figure may be lived by obstacle graph shealtering completely, causes showing.By fine setting be blocked lines and the edge of figure, the fuzzy position of closing on that is penetrated into of the figure that makes to be blocked.
Image as shown in Figure 4, the figure that is blocked seems discontinuous owing to being subject to blocking of obstacle figure, and lines seem stiff.As shown in Figure 5, finely tune lines and the edge of the figure that is blocked, the figure that makes to be blocked is fuzzy, and it is many that image has just seemed coherent nature.
(7) judge whether to have living space and place the figure not being blocked.
If be blocked, figure around has living space and places the figure not being blocked, and the figure not being blocked is placed on and is blocked figure around.Observer, by the part for being blocked in the figure not being blocked and the figure that is blocked, can carry out association to the whole figure that is blocked, thereby understands better the content of the figure that is blocked.
