Embodiment 1
It is that example describes that present embodiment all obtains from a width of cloth original image with all objects.As shown in Figure 2, may further comprise the steps:
The first step: load original image, obtain the essential information of original image;
The essential information of original image comprises: size of images (long and wide), each color of pixel value (rgb value) in the image.
Second step: according to the object that the user selects, original image is cut apart, one or more object that the user selects is separated from this original image, and storage separately;
The preferred image segmentation algorithm (or claiming to scratch nomography) that adopts is cut apart original image.The mode of specifically cutting apart is a lot, for example can adopt specific shape to cut apart, such as: rectangle, circle etc.; Also can adopt some algorithms to carry out cutting apart of intelligence, as average drifting algorithm, minimal cut/max-flow algorithm etc.
Separate a plurality of objects if desired, once cut apart an object usually,, isolate a plurality of objects by operation image partitioning algorithm repeatedly.Carried out for the 3rd step again after all objects that will separate are all split.
The 3rd step: receive the object that from original image, intercepts, those objects are positioned in the background image, obtain first plane picture;
The position relation of placing also can exert an influence to the degree of depth level (the convex-concave level during three-dimensional display) of follow-up stereo display.The object that is positioned at the upper strata is positioned at the object of lower floor from visually protruding more.
Each color of pixel value is according to the color value of each color of pixel value, background image on the object that is intercepted in first plane picture, and the placement of object relation decides, from the common color value of forming first plane picture of the color value of visible object of viewpoint and/or background.
The above-mentioned background image can be the new image of a width of cloth, perhaps can be original image, can also be the image that obtains through after three-dimensional the processing.
In this step, when being positioned over object in the background image, it is the setting of position that the positional information of the object that can be provided with according to the user is placed.Adopt this kind mode, the placement of each object relation was given the bigger degree of freedom of user, better user experience when the user can be provided with three-dimensional display voluntarily.

1, first convex-concave parameter according to each pixel correspondence of this object of convex-concave calculation of parameter of all character pixel correspondences on a certain object of user's setting:
1) establishing the point of establishing the convex-concave parameter is: P1, P2, P3.....PN, corresponding convex-concave parameter value is: V1, V2, V3, ... .VN, for other any 1 PX on this object, calculate its distance to the point of establishing the convex-concave parameter (distance herein is meant the distance on the two dimensional surface), be made as: D1, D2, D3, ... .DN, wherein D1 is the distance that PX is ordered to P1, and D2 is the distance that PX is ordered to P2, by that analogy;
2) calculate the convex-concave V parameter X that PX is ordered by the linear weighted function method:
VX=a
1* (D1/D) * V1+a
2* (D2/D) * V2+a
3* (D3/D) * V3+...+a
N* (DN/D) * VN (formula 1)
Wherein, D=D1+D2+D3+.....+DN; A is a weight coefficient, a＞0.For the sake of simplicity, preferably, a=1.
Repeat above-mentioned steps 1), 2) calculate the convex-concave parameter of all pixel correspondences on this object.
2, repeat above-mentioned steps 1 and respectively each object on first plane picture is calculated, obtain the convex-concave parameter of each pixel correspondence on first plane picture.

Step 2 is offset each pixel according to offset parameter, obtains one second plane picture;
If generate several second plane pictures, then repeat above-mentioned steps 1 and step 2, at this moment, for same pixel, the offset parameter of second second plane picture is different with the offset parameter of first second plane picture, offset parameter can increase along with the number difference of image, for example: be 1 pixel for the convex-concave parameter, the distance of skew is N for the first time, and when calculating second second plane picture, its offset distance is 2*K*N, when calculating the 3rd second plane picture, its offset distance is 3*K*N, by that analogy, can obtain several second plane pictures, wherein, 2 and 3 are respectively current skew number of times, and the K value can be set by the user, perhaps the default value that provides for system.
For the blank pixel of image, use the mode of image repair to fill.
Adopt above-mentioned image shift algorithm that pixel is offset, finally be offset out second plane picture that or many and first plane picture have parallax.Can obtain stereo-picture after several second plane pictures are synthetic, perhaps with first plane picture and second plane picture as about figure also can obtain stereo-picture after synthetic.
