Fig. 2 is shown according to an exemplary embodiment a kind of for generating the flow chart of the method for three components.
As shown in Fig. 2, carrying out image procossing in S202 to predetermined image and generating the first image, the first image is Bianry image.It can for example, image dividing processing is carried out to the predetermined image, obtains segmentation data；And by described Divide data and generates the first image.As described above, in the first image, the pixel number of object foreground part is arranged to 0, Object background is arranged to 255.Image segmentation is commonly used in the object and boundary (line, curve etc.) in positioning image.Image point Cutting is the tagged process of each pixel in image, this process makes the pixel with same label have certain Common visual characteristic.Image segmentation the result is that the set of image sub-zones, or the collection of contour line extracted from image It closes.In one sub-regions each pixel is under the measurement of certain characteristic or the characteristic by being calculated is similar, example Such as color, brightness, texture.Neighboring region is very different under the measurement of certain characteristic.Common image segmentation algorithm packet Include: the method based on edge detection, threshold segmentation method, region growing, regional split merging etc., the application is not limited.
In S204, according to the pixel in predefined parameter and the first image, pixel location data is generated.It can be such as Comprise determining that parameter preset numerical value；Around each pixel in the first image, generated by the parameter preset pre- Fixed pixel location data；And the pixel location data is marked by default value.Wherein, described by described default Parameter generates predetermined pixel location data, comprising: N=(2 × M+1)2-1；Wherein, N is predetermined pixel quantity, and M is default Parameter, and be positive integer.
In one embodiment, a series of pixel location data is generated by the following method.If the picture of segmenting edge Element outwardly and inwardly extends 1 pixel simultaneously, can for example be denoted as M=1, and the location of pixels of generation is that-M arrives M, do not include origin (0, 0).The number for generating pixel is N=(2 × M+1)2- 1, wherein M is parameter preset, and is positive integer.It can refer to the example of Fig. 3, As M=1, the pixel location data of some pixel to be calculated is 8, as M=2, some pixel to be calculated Pixel location data is 25.It also may be, for example, these location of pixels assignment, to distinguish, pixel value can for example such as Shown in Fig. 3.
In another embodiment, the pixel of segmenting edge outwardly and inwardly extends 2 pixels simultaneously, is denoted as M=2.It can join The example for examining Fig. 3, as M=2, the pixel location data of some pixel to be calculated is 25.It also may be, for example, these pictures Plain position assignment, to distinguish, the value of location of pixels can for example as shown in Figure 3.
In S206, by the pixel location data by the first image all pixels with it is surrounding Pixel carries out pixel value judgement, generates the second image according to judging result.It can be for example, for each of the first image picture Element, compared with carrying out the numerical value of pixel value with other surrounding N number of pixels.Compared according to numerical value as a result, to pixel is represented The attribute value in the region carries out assignment (setting it to uncertain region) again, to generate the second image.
In S208, by the first image and second image, three components of predetermined image are generated.Generation and institute The identical third image of the first picture size is stated, the third image all pixels value is 255；It generates and the first image ruler Very little identical 4th image, the 4th image all pixels value are 128；And by second image, the third image Image superposition is carried out with the 4th image to generate three components of predetermined image.
Method according to the present invention for generating three components, by being compared to each pixel in bianry image It calculates, obtains uncertain region, and then generate the mode of three components, three points can be generated on the basis of only bianry image Figure, and improve the efficiency for generating three components.
In a kind of exemplary embodiment of the disclosure, further includes: carry out the predetermined image by three component FIG pull handle.Figure can be scratched for example including Bayes in image FIG pull handle field, kNN scratches figure and Poisson scratches figure (Poisson ) etc. Matting Processing Algorithm, will for example can be inputted in above-mentioned stingy nomography by the present processes, be handled.
It will be clearly understood that the present disclosure describe how being formed and using particular example, but the principle of the present invention is not limited to These exemplary any details.On the contrary, the introduction based on present disclosure, these principles can be applied to many other Embodiment.
Fig. 4 be show according to another exemplary embodiment it is a kind of for generating the flow chart of the method for three components.
Wherein, in S402, the pixel i in the first image is obtainedn。
In S404, pixel i is obtained according to the pixel location datanThe N number of pixel of surrounding.It can be for example, working as M= When 2,25 other pixels in pixel peripheral location to be calculated are obtained.
In S406, by pixel inPixel value be compared respectively with the pixel value of pixel N number of around it.Wherein It can be for example, reading the pixel value of 25 other pixels.Since the first pixel map is bianry image, so pixel value may be 255, it is also possible to be 0.
In S408, when by pixel inPixel value and around it when the pixel value difference of N number of pixel, by the picture Vegetarian refreshments inAttribute value be set as predetermined value.It can be for example, working as pixel inPixel value and around it N number of pixel pixel value When different, by pixel inIt is considered as uncertain region, and then by pixel inPixel value be assigned a value of 128.As pixel inWith week Enclose 25 pixels numerical value it is all right identical when, keep pixel inRaw value it is constant.
In S410, judges whether to have stepped through pixel all in the first image, if not traversing completion, continue Pixel is read to be handled.If having stepped through completion, enter S412.
In S412, the second image is generated.It can be for example, the first image after pixel value again assignment processing be made For the second image.
It is described by the first image and second image in a kind of exemplary embodiment of the disclosure, it generates Three components of predetermined image, comprising: generate third image identical with the first image size, all pictures of third image Element value is 255；The 4th image identical with the first image size is generated, the 4th image all pixels value is 128；With And by second image, the third image generates three components of the predetermined image with the 4th image.
It is described by second image in a kind of exemplary embodiment of the disclosure, the third image with it is described 4th image generates three components of the predetermined image, comprising: described by second image by three component calculation formula Third image and the 4th image carry out three components that image superposition generates the predetermined image；
Wherein three component calculation formula are as follows:
Itrimap=Ibinary-Itemp1+Itemp2；
Wherein ItrimapFor three components, IbinaryFor second image, Itemp1For the third image, Itemp2It is described 4th image.
