Embodiment
One embodiment of the invention provides a kind of image processing method, and this method is applied to a pending image, and pending image is a 2D image, changes the image resource of 3D rendering technology as the 2D image.
For making more detail knowledge the present invention of those skilled in the art, describe the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, pending image 10 comprises foreground object zone 101 and background subject area 102, and foreground object zone 101 and background subject area 102 have hiding relation.For realizing that the 2D image changes the 3D rendering technology, adopt the synthetic structure of image left and right sides eye pattern, the present pixel shift method that adopts, and have hiding relation foreground object zone 101 and a background subject area 102, because depth value difference, translational movement are also different, after the pixel translation, owing to do not know the pixel value of occlusion area, " Hole " zone 403 as shown in Figure 4 will occur.
Change " Hole " problem that occurs in the 3D rendering technology in order to solve the 2D image, as shown in Figure 2, Fig. 2 is the process flow diagram of image processing method in one embodiment of the invention, and the method for present embodiment comprises:
Step 210: the depth value that obtains the foreground object zone of pending image;
Step 212: based on the depth value in foreground object zone, determine to state the translational movement in foreground object zone;
Step 214: based on the depth value in foreground object zone, determine the stroke in foreground object zone;
Step 216: handle the foreground object zone based on translational movement and stroke.
Wherein, in step 210, obtain the depth value in the foreground object zone of pending image.Be specially: adopt SfM method (from exercise recovery structure method), DfC method (Depth from cues degree of depth clue method) or MLA method (Machine Learning Algorithm machine learning algorithm) to obtain the depth value in the foreground object zone of pending image, SfM method wherein, namely utilize physical relations such as amount of movement, camera motion and the object of object in the image move in three dimensions, the depth value of estimation image.SfM method, DfC method, MLA method are those skilled in the art to be familiar with, so do not repeat them here, certainly, in other embodiments, also can obtain depth value by other means, and the present invention is not restricted.For convenience of description, the depth value in foreground object zone is designated as D1, in addition, in the present embodiment, the depth value D1 in described foreground object zone is the absolute depth value, and unit is rice (m).For example, in the pending image 10 shown in Figure 1, the depth value D1 that adopts the SfM method can obtain foreground object zone 101 is 3m.In another embodiment, the depth value D1 in described foreground object district can be the relative depth value, uses 8 gray-scale maps to represent, scope is 0-255, the relative depth value can be converted into the absolute depth value, carries out the unit unification, in following each embodiment, for convenience of description, all adopt the absolute depth value.
In step 212, based on the depth value in foreground object zone, determine the translational movement in foreground object zone.Be specially: based on the depth value D1 in foreground object zone, by formula S 1=D1*c/ (2* (D1+b)), can determine the translational movement S1 in foreground object zone, in addition, in the present embodiment, the translational movement S1 in described foreground object zone, unit is rice (m), c represents the distance between two of user, and b represents two bee-lines to the screen that shows pending image of described user.For example, as shown in Figure 3, show foreground object zone 101 on the screen 30, background subject area 102, known c is 0.05m, b is 5m, D1 is 3m, above data substitution is calculated, and according to formula S 1=D1*c/ (2* (D1+b)), the translational movement S1 that can calculate foreground object zone 101 is 0.0067m.In another embodiment, the translational movement in described foreground object zone also can adopt relative translation amount S1 ', represents with number of pixels, be S1 '=S1/p, wherein p is the size of a pixel horizontal direction of display, in following each embodiment, for convenience of description, all adopt absolute translational movement.
Before step 214, this method also comprises: obtain pending image the background subject area depth value and based on the depth value of background subject area, determine the translational movement of background subject area.The depth value that obtains the background subject area of pending image is specially: adopt SfM method, DfC method or MLA method to obtain the depth value of the background subject area of pending image, for convenience of description, the depth value of background subject area is designated as D2, obtain three kinds of methods of depth value, namely SfM method, DfC method, MLA method are those skilled in the art and are familiar with, so do not repeat them here, certainly, in other embodiments, can obtain depth value by other means, the present invention is not restricted yet.In addition, in the present embodiment, the depth value D2 of described background subject area is the absolute depth value, and unit is rice (m).For example, in the pending image 10 shown in Figure 1, the depth value D2 that adopts the SfM method can obtain background subject area 102 is 5m.In another embodiment, the depth value D2 of described background subject area is the relative depth value, uses 8 gray-scale maps to represent, scope is 0-255, the relative depth value can be converted into the absolute depth value, carries out the unit unification, in following each embodiment, for convenience of description, all adopt the absolute depth value.
Depth value based on the background subject area, determine the translational movement of background subject area, be specially: based on the depth value D2 of background subject area, by formula S 2=D2*c/ (2* (D2+b)), can determine the translational movement S2 of background subject area, in the present embodiment, the translational movement S2 of background subject area is absolute translational movement, unit is rice (m), and c represents the distance between two of user, and b represents two bee-lines to the screen that shows pending image of described user.For example, as shown in Figure 3, show foreground object zone 101 on the screen 30, background subject area 102, known c is 0.05m, b is 5m, D2 is 5m, above data substitution is calculated, and according to formula S 2=D2*c/ (2* (D2+b)), the translational movement S2 that can calculate background subject area 102 is 0.0125m.In another embodiment, the translational movement of described background subject area also can adopt relative translation amount S2 ', represents with number of pixels, be S2 '=S2/p, wherein p is the size of a pixel horizontal direction of display, in following each embodiment, for convenience of description, all adopt absolute translational movement.
In step 214, based on the depth value in foreground object zone, determine the stroke in foreground object zone.Be specially: based on the translational movement of background subject area and the translational movement in foreground object zone, determine pending image pending zone size and based on the size in pending zone, determine the stroke in foreground object zone.Wherein, pending zone is of a size of the absolute value of difference between the translational movement of the translational movement in foreground object zone and background subject area | and S1-S2|, pending zone i.e. " Hole " zone.Size according to pending zone | S1-S2|, utilize formula Z=(2*|S1-S2|) to determine the stroke Z of foreground object.For example, when the 2D image changes 3D rendering left eye figure into, by aforementioned S1 and the S2 of calculating, foreground object among Fig. 1 zone 101 and background subject area 102 are carried out can obtaining as shown in Figure 4 foreground object regional 401 and background subject area 402 according to the translational movement S2 of the translational movement S1 in foreground object zone 101 and background subject area 102 respectively to left after, because S1 and S2 vary in size, be that foreground object zone 101 is different with background subject area 102 translational movements, so " Hole " zone 403 will occur, according to formula Hole=|S1-S2|, the size that can calculate " Hole " zone 403 is 0.0058m.Among Fig. 4, according to formula Z=2*|S1-S2|, the stroke that can calculate foreground object zone 401 is 0.0116m, i.e. foreground object zone each broadening 0.0058m of 401 the right and lefts.
In step 216, handle the foreground object zone based on translational movement and stroke.Human-eye visual characteristic shows, for same object, and the size difference of human eye impression during different distance, the close shot size is bigger than distant view.Utilize this principle, foreground object area size is increased, " Hole " zone will be automatically by the foreground object regional occlusion like this, thereby solves " Hole " filling problem.For example, the foreground object zone 401 among Fig. 4 being amplified, is 0.0116 to amplify when foreground object zone 401 being carried out according to stroke.Fig. 5 comprises among Fig. 5 that for through the image after the processing after handling by amplification, " Hole " zone 503 is blocked in foreground object zone 501 through amplifying foreground object zone 501, background subject area 502 and " Hole " zone 503 after handling.
Further, processing procedure also comprises, adopts antialiasing processing region edge, reduces regional discontinuous sense, makes the image nature.
In another embodiment, in step 212, based on the depth value in foreground object zone, determine the translational movement in foreground object zone.Be specially: based on the depth value in foreground object zone, according to formula S 1=K*D1, wherein K is scale factor, determines the translational movement in foreground object zone.In one embodiment, can carry out a large amount of sample experiments by formula S 1=D1*c/ (2* (D1+b)), test the result factually and show that the depth value in the translational movement in foreground object zone and foreground object zone is proportionate relationship, 1=K*D1 represents with formula S.For example, in the pending image 70 shown in Figure 7, foreground object zone 701 and background subject area 702 are when screen display, and viewing effect is that foreground object zone 701 and background subject area 702 are positioned at before the screen, and the span of K is 0.05-0.1 in the S1=K*D1 formula in this case.The depth value D1 in known foreground object zone 701 is 3m, makes that the K value is at 0.05 o'clock, substitution formula S 1=K*D1, and the translational movement S1 that can calculate foreground object zone 701 is 0.15m.
In step 214, based on the depth value in foreground object zone, determine the stroke in foreground object zone.Be specially: based on the mapping table of depth value and expansion and contraction, reach the depth value based on described foreground object zone, determine the stroke in described foreground object zone.For example, in the pending image shown in Figure 1, the depth value D1 in foreground object zone 101 is 3m, mapping table Fig. 6 of query depth value and expansion and contraction as can be known, when D1 was 3m, corresponding expansion and contraction was 0.1, and stroke is the product of described expansion and contraction and foreground object zone 101 sizes, the foreground object zone 101 of supposing Fig. 1 is of a size of a unit area, and then Dui Ying stroke is 0.1m.
In step 216, handle the foreground object zone based on translational movement and stroke.Be specially: based on translational movement, determine the pending zone in the pending image.Based on stroke, with the processing of stretching of foreground object zone.Human-eye visual characteristic shows, for same object, and the size difference of human eye impression during different distance, the close shot size is bigger than distant view.Utilize this principle, foreground object area size is increased, " Hole " zone will be automatically by the foreground object regional occlusion like this, thereby solves " Hole " filling problem.For example, when the 2D image changes 3D rendering right eye figure into, translational movement S1 according to foreground object zone 101 carries out to right translation with the foreground object zone 101 among Fig. 1, obtains foreground object zone 701 as shown in Figure 7 after the translation, will occur " Hole " zone 703 after the translation.Foreground object zone 701 among Fig. 7 is amplified, and is 0.1 to carry out equal proportion and amplify when foreground object zone 701 being carried out according to expansion and contraction.Fig. 8 is through the image after handling, and Fig. 8 comprises foreground object zone 801, background subject area 802 and " Hole " zone 803, and after handling by amplification, " Hole " zone 803 is blocked in foreground object zone 801.
After step 216, also further whether there is " Hole " zone between the background subject area of the described foreground object zone after the judgment processing and described pending image, if, then interpolation processing is carried out in described " Hole " zone, utilize the neighbor pixel interpolation to obtain " Hole " area pixel, because " Hole " zone after step 216 is handled is very little, even do not had, so need the elemental area of interpolation processing very little, so with respect to the method for all using pixel prediction in the prior art, better effects if.
Further, after step 216, processing procedure also comprises, adopts antialiasing processing region edge, reduces regional discontinuous sense, makes the image nature.
One embodiment of the invention also provides a kind of electric terminal, and as shown in Figure 9, electric terminal comprises:
As shown in figure 10, processing unit 901 also comprises first process chip 9011, be used for before the stroke of determining the foreground object zone, obtain pending image the background subject area depth value and based on the depth value of background subject area, determine the translational movement of background subject area.
