In embodiments of the present invention, pattern after the coding can be carried out by one or more solution code mask Decoding, obtains the recovery pattern corresponding to a master pattern.With by with corresponding to one in the following examples of the present invention Solution code mask enters line aliasing with pattern after the coding and obtains the recovery pattern to be described.Those skilled in the art can be with Know, the embodiment of the present invention can also be decoded by multiple solution code masks to pattern after the coding.
The step of embodiment of the present invention, is further described below：
In some embodiments, it is described restore pattern can complete table the information that is included in the master pattern is shown, It is but not fully consistent with the master pattern.In preferably embodiment, the recovery pattern and the master pattern base This is consistent.
When the recovery pattern is not quite identical with master pattern, preferably experienced in order that obtaining user, one In a little embodiments, enhancing processing can be carried out to the recovery pattern so that user see with master pattern similarity it is higher, Or user's visual experience preferably strengthens recovery pattern.
Therefore, in a kind of possible embodiment of the embodiment of the present invention, methods described also includes：
Pattern strengthens step, obtains at least one enhancing template according to the recovery pattern, by the enhancing template aliasing extremely On the recovery pattern, pattern is restored in the enhancing for obtaining being presented on the user eyeground.
For example, in one embodiment, the information that can obtain including in the master pattern according to the recovery pattern, Described information is, for example, the text information being included in master pattern, but restores the text information and background parts of pattern Contrast compared to being decreased with master pattern, therefore user is While it can be seen that the text information, but visual experience It is bad.At this point it is possible to pass through an enhancing template so that the pixel quilt restored on pattern with the text information corresponding part Blacken, pixel is highlighted corresponding to background parts so that the contrast of the text information and background parts increases, and user passes through What the enhancing template and recovery pattern of the aliasing can be apparent from sees the text information, improves Consumer's Experience.
In one embodiment, the size and in the same size, the step of pattern after the coding of the solution code mask Rapid S130 is further to set the solution code mask with pattern registration after the coding so that the solution code mask and coding The pixel cell in the corresponding region of pattern is overlapping afterwards, mixes, and then obtains the recovery pattern.In another embodiment, institute The setting that solution code mask can not also be completely superposed with pattern after the coding is stated, such as passes through United States Patent (USP) US7706025B2 When the striped solution code mask of middle announcement decodes to pattern after the coding, it is only necessary to which the position for solving the striped of code mask causes The striped interferes effect i.e. it can be seen that the hiding information with pattern after coding.
As shown in Fig. 2 in the present embodiment, described information exchange method also includes before the pattern reconstitution steps：
S110 pattern coding steps, by multigroup encoder for interfering value in setting range correspondingly to more Individual master pattern is encoded, and obtains pattern after multiple just codings, wherein, every group of encoder includes at least one encoder；
S120 pattern combining steps, will it is the multiple just encode after pattern synthesize one coding after pattern.
In the step S110, such as need to compile two master patterns (generally different master patterns) Code, then need to use two groups of encoders to be encoded respectively to described two master patterns, i.e.,：By first group of encoder to One master pattern is encoded pattern after coding at the beginning of obtaining first；Again by second group of encoder to second master pattern Encoded pattern after being encoded at the beginning of obtaining second.Wherein, an only encoder is possible in one group of encoder, it is also possible to Including multiple encoders, to only have an encoder to illustrate in one group of encoder in following embodiments of the invention, ability The technical staff in domain can also include multiple encoders it is recognised that in the embodiment of the present invention in one group of encoder.
In embodiments of the present invention, value is interfered in a setting range between multigroup encoder, it is described here Interfere value be, for example, multigroup encoder between dot-product operation value.
The mode of pattern can be after pattern synthesizes a coding after the multiple just being encoded in the step S120：
Pattern after pattern aliasing after the multiple just coding is encoded into one；Such as it is multiple just encode after pattern correspondence The color value of pixel is with the regular overlapping, mixing of a setting；Or
Some pixels are extracted on pattern after each just coding respectively, wherein the pixel extracted after different just codings on pattern Position it is misaligned, then the position by the pixel of diverse location extraction on pattern after this respectively coding at the beginning of the difference according to original pixel Synthesize one coding after pattern.Such as in one embodiment, just pattern includes after coding：First just encode after pattern and Second just encode after pattern, wherein, will described first just encode after pattern odd-numbered line even column and even number line odd column Pixel extraction comes out, then will described second just encode after the odd-numbered line odd column of pattern and the pixel extraction of even number line even column Out, then by the pixel extracted in pattern after the coding at the beginning of described first and second according to it respectively described first and the Two just encode after position correspondence in pattern be filled into after coding in pattern, just form one and just compiled with described first and second Pattern after pattern magnitude identical coding after code.
Certainly, those skilled in the art are it is recognised that other methods for suitably synthesizing multiple patterns can also be applied In the embodiment of the present invention.
In a kind of possible embodiment, the encoder is coding templet.
The step of being encoded to the master pattern includes：By the coding templet and the master pattern aliasing.
In one embodiment, the size one of master pattern of the size of the coding templet with needing hiding information Cause.In one embodiment, the coding templet is mixed, is overlapping pixel by pixel with the master pattern, that is, passes through volume The pixel that each pixel on code mask is entered to corresponding pixel on the master pattern after aliasing corresponding to line aliasing acquisition, this Pixel after a little aliasings forms the pattern after just encoding.Certainly, those skilled in the art is it is recognised that the master pattern It is possible to be embedded in the part in a larger pattern or for the larger pattern, at this point it is possible to only in the larger pattern The master pattern region carry out the coded treatment, the pattern of the other parts of the larger pattern keeps constant.
Certainly, the encoder described in the other embodiments of the embodiment of the present invention is possible to for an encryption algorithm, pass through one Encryption algorithm carries out coded treatment to the master pattern, obtains pattern after the just coding.Such as pass through a coded sequence pair Each pixel of master pattern carries out coded treatment.
In a kind of possible embodiment of the embodiment of the present invention, the coding templet is a coding pattern.The figure Case is by each passage of a color space (R, G, B, A (red, green, blueness, transparency) passage in RGBA color space；Or C, M, Y, K (cyan, magenta, yellow, black) passage in CMYK color space etc.) in one or more compositions.In one kind In possible embodiment, the relation between each group coding templet is mutually orthogonal.
In embodiments of the present invention, the solution code mask is also a decoding pattern.The decoding pattern is also empty by a color Between one or more compositions in each passage.
In embodiments of the present invention, the coding templet is conciliate code mask and can obtained by following two method：
1) coding templet is obtained first, then solves code mask according to corresponding to coding templet generation；
2) the solution code mask is obtained first, then the coding templet according to the decoding template generation.
Both modes are described in more detail separately below：
In a kind of possible embodiment, multigroup coding templet is generated by multiple pseudo-random sequences, with more added with Information in the hiding master pattern of effect.
Now, methods described typically also includes：
Template generation step is decoded, according to one group of coding templet, one solution code mask of corresponding generation.
In the present embodiment, for example, can be to generate the solution code mask in information providing end, it be then forwarded to specific Ustomer premises access equipment so that the specific ustomer premises access equipment can use the solution code mask by the partial content solution of pattern after coding Code, obtains the information included in the master pattern.Certainly, can also be the letter in alternatively possible embodiment Breath provides end and the encoder or coding templet is supplied into ustomer premises access equipment, and ustomer premises access equipment generates according to the coding templet The solution code mask.
In a kind of possible embodiment, by becoming to the coding templet in the decoding template generation step Get the solution code mask in return.Here conversion can be anti-phase processing or the anti-phase processing with compensation, specific transform method It can specifically give, repeat no more here below.
In alternatively possible embodiment, the solution code mask can also be generated by a pseudo-random sequence.Wherein, institute Stating solution code mask can generate in information providing end, can also be generated in user terminal.
Now, methods described also includes：
Coding templet generation step, the coding templet is correspondingly generated according to the solution code mask.
For example, the coding templet can be obtained by the decoding template transformation.Wherein, it is described be transformed to it is anti-phase processing, Or the anti-phase processing with compensation.The step of obtaining coding templet by the solution code mask above with coding templet with being decoded The step of template, is similar, and here is omitted.
In embodiments of the present invention, the method for pattern after solution code mask aliasing to the coding on user eyeground can be had It is a variety of, such as：
The solution code mask is directly projected to user eyeground so that solution code mask mixes with pattern after the coding on user eyeground It is folded, and then cause user pattern position after the coding to see the recovery pattern after aliasing；
Or the solution code mask can be inserted between pattern after the eyes and the coding of user, by the solution Eyeground aliasing of the pattern in user after code mask and coding.Such as wear an intelligent glasses, and the intelligent glasses in user Eyeglass in the eyes of user and during by between viewing object, by showing that the solution code mask can be realized on the eyeglass Above-mentioned function.
Certainly, in a kind of possible embodiment, it is possible to both to the solution code mask of user eyeground projection one, and in user Insert another solution code mask in light path after eyes and decoding between pattern, by two solution code masks simultaneously to the decoding after Pattern is decoded.
Therefore, in a kind of possible embodiment of the embodiment of the present invention, the pattern reconstitution steps S130 includes：
Information projection step, the solution code mask is projected to the eyeground of the user.
In alternatively possible embodiment, include in the pattern reconstitution steps S130：
Information display step, the decoding is shown in the light path between pattern after the eyes and the coding of the user Template.
In the embodiment of the embodiment of the present invention, due to the solution code mask is directly presented on into user's by projection The mode on eyeground is mainly superimposed to decode by pattern after solving code mask and coding；And the decoding mould is presented by showing The mode of plate can cover the corresponding region of pattern after the coding, therefore, pin by corresponding region on the solution code mask To both solution code mask presentation modes, it is necessary to which coding templet conciliates code mask corresponding to selecting.Be given below respectively with this two The embodiment of decoding and coding corresponding to kind mode：
1) when the solution code mask is presented by way of information projection：
Assuming that eyes see piece image A, separately there is the image B that a width projects eyeground, then the figure that brain actually obtains As C is exactly image B and image A superimposed image.Superposition Formula is as follows：
F (C)=f (B)+f (A) (1)
RGB component primary color value that f (x) is pixel x in an image (in present embodiment using use RGBA color space as Example, but not limited to this), span be 0 to 1, wherein 0 correspond to it is completely black, 1 correspond to each color component pure color.f (C)=f (B)+f (A) represents the RGB that the RGB component primary color value of each pixel in image C is respective pixel in image B and image A Component primary-color value sum.
It is as follows to n-th of master pattern Sn cataloged procedure using above-mentioned formula in embodiments of the present invention：
F (Cn)=f (Pn)+f (Sn) (2)
Wherein Pn is coding pattern corresponding with n-th of master pattern, and Cn is to be encoded by n-th of master pattern Pattern after the first coding obtained afterwards, n are the natural number from 1 to N, and N is the total number of the master pattern.
In the embodiment of the present invention, the RGB component primary color value of each pixels of pattern C can pass through following formula after the coding Obtain：
F (C)=f (C1)+f (C2)+... f (CN) (3)
The decoding process of pattern after just coding similar can be expressed as：
F (Cn ')=f (Pn ')+f (C) (4)
Wherein Pn ' decodes pattern to be corresponding with n-th of master pattern, and Cn ' restores to be corresponding with n-th of master pattern Pattern (pattern after decoding).Recovery pattern Cn ' corresponding with n-th of master pattern expression way can so be derived For：
F (Cn ')=f (Pn ')+f (Pn)+f (Sn) (5)
Below exemplified by having two master patterns, pattern C2 aliasings after pattern C1 and second is just encoded after first is just encoded Pattern C after into a coding, then
F (C1 ')=f (P1 ')+f (C1)+f (C2)
=f (P1 ')+f (P1)+f (S1)+f (P2)+f (S2) (6)
F (C2 ')=f (P2 ')+f (C1)+f (C2)
=f (P2 ')+f (P1)+f (S1)+f (P2)+f (S2) (7)
In above-mentioned formula, when the first solution code mask P1 ' and the second solution code mask P2 ' meet by formula (8) and formula (9) group Into equation group, it is possible to user eyeground obtain with the first master pattern S1 and the second master pattern S2 compared with dynamic range contracting Small first restores pattern C1 ' and second and restores pattern C2 '：
F (P1 ')+f (P1)+f (P2)+f (S2)=c1 (8)
F (P2 ')+f (P1)+f (S1)+f (P2)=c2 (9)
Set up, be then immediately seen respectively with the first solution code mask and the second corresponding user's can of solution code mask respectively dynamic For the first master pattern S1 of [0,1-c1], (the master pattern S1 of the reduced dynamic range is described first multiple to state range shorter Original pattern C1 '), reduced dynamic range is the second master pattern S1 of [0,1-c2].Wherein, it is normal between c1 and c2 is 0 to 1 Number, typically between 0 to 0.5.
Due to master pattern Sn, it is known that if coding pattern Pn is established by pseudo-random process (such as by a pseudorandom Sequence obtains), as long as then constructing decoding pattern P n ' by equation below, it is possible to by the decoding pattern P n ' to the volume Pattern C is decoded after code：
F (P1 ')=c1- [f (P1)+f (P2)+f (S2)] (10)
F (P2 ')=c2- [f (P1)+f (S1)+f (P2)] (11)
Certainly, those skilled in the art is by pseudo-random process it is recognised that when establishing the decoding pattern P n ', Coding pattern Pn can also be obtained by the way that above formula (8) and (9) are corresponding.
2) the decoding mould is presented by way of code mask is solved insertion in the light path between eyes and recovery pattern During plate：
A kind of transparent image aliasing algorithm common at present is used as Alpha Blending algorithms：
Assuming that there are piece image A, another transparent image B, then the image C for seeing image A, obtaining is removed through image B It is exactly image B and image A mixed image.If image B transparency be a (a value be 0 to 1,1 correspond to it is fully transparent, 0 Corresponding to completely opaque).Alpha Blending algorithmic formulas are expressed as follows：
F (C)=(1-a) * f (B)+a*f (A) (12)
Wherein, f (x) is the RGB component primary color value of pixel x in an image, and span is 0 to 1, wherein 0 corresponds to entirely Black, 1 corresponds to the pure color of each color component；A is the transparency of each pixel in pattern B.
Therefore, in the embodiment of the present invention, carrying out cataloged procedure to n-th of master pattern Sn can be expressed as by formula：
F (Cn)=(1-an) * f (Pn)+an*f (Sn) (13)
Wherein, Pn is coding pattern corresponding with n-th of master pattern Sn, and Cn is and n-th of master pattern Pattern after just being encoded corresponding to Sn, an are the transparency of each pixel in coding pattern Pn.
Pattern C can be obtained by following formula after the coding synthesized by pattern Cn after N number of just coding：
F (C)=f (C1)+f (C2)+... f (CN) (14)
Decoding process corresponding with above-mentioned cataloged procedure similar can be expressed as：
F (Cn ')=(1-an ') * f (Pn ')+an ' * f (C) (15)
Wherein Pn ' decodes pattern to be corresponding with n-th of master pattern Sn, and Cn ' is corresponding with n-th of master pattern Sn Pattern is restored, an ' is the transparency of each pixel in decoding pattern P n '.The expression way for restoring pattern Cn ' can so be derived For：
F (Cn ')=(1-an ') * f (Pn ')+an ' * [f (C1)+f (C2)+... f (CN)] (16)
By taking the process coded and decoded to first master pattern S1 and second master pattern S2 as an example.
F (C1 ')=(1-a1 ') * f (P1 ')+a1 ' * [f (C1)+f (C2)]=(1-a1 ') * f (P1 ')+a1 ' * (1-a1) * f (P1)+a1’*a1*f(S1)+a1’*(1-a2)*f(P2)+a1’*a2*f(S2) (16)
F (C2 ')=(1-a2 ') * f (P2 ')+a2 ' * [f (C1)+f (C2)]=(1-a2 ') * f (P2 ')+a2 ' * (1-a1) * f (P1)+a2’*a1*f(S1)+a2’*(1-a2)*f(P2)+a2’*a2*f(S2) (17)
Due to a1*a1 ' and a2*a2 ' it can keep for the constant of each pixel, as long as so meeting two following formula (18) and (19), then two master patterns S1 and S2 can be by decoding pattern P 1 ' and P2 ' decode to obtain come aliasing corresponding to Restore pattern C1 ' and C2 '：
(1-a1 ') * f (P1 ')+a1 ' * (1-a1) * f (P1)+a1 ' * (1-a2) * f (P2)+a1 ' * a2*f (S2)=d1 (18)
(1-a2 ') * f (P2 ')+a2 ' * (1-a1) * f (P1)+a2 ' * (1-a2) * f (P2)+a2 ' * a1*f (S1)=d2 (19)
Because d1, d2 are constant, first master pattern S1 and second master pattern S2 are in coding side, it is known that code pattern Case P1 and P2 can be generated by pseudo-random sequence, can obtain corresponding decoding pattern by solving above-mentioned formula (18) and (19) P1 ' and P2 '.
Recovery pattern Cn corresponding with n-th of master pattern Sn is it can be seen from above formula (16) to (19) State range shorter is n-th of master pattern Sn of [0, an*an '-dn], and wherein an*an '-dn value typically exists between 0 to 1 Between 0.5 to 1.
From the above, it can be seen that one user uses during multichannel situation decoding pattern P n ' need it is original with other users Pattern is associated, but due to after coding the multiple decoding pattern Ps 1 of pattern C aliasings arrive PN information, remain able to ensure certain journey The security of degree.
Because RGBA span is 0 to 1, the coding and decoding process of above two method need appropriate limitation or The span of the primary color value of master pattern and each pixel color component of encoding and decoding pattern is compressed, is gone out with avoiding or reducing value The problem of dtmf distortion DTMF brought during boundary, the problem have solution, no longer described herein in the prior art.
In addition to method described above, the embodiment of the present invention can also be corresponding to obtain by other suitable algorithms Decode or encode template.
In some embodiments, scheme after the coding being identified according to the characteristics of image of itself of pattern after coding Case.In other possible embodiments, the volume is determined in order to can quickly be identified in follow-up corresponding decoding process Pattern after code, methods described may also include after the pattern coding step：

When methods described, which includes the positioning, identifies setting steps, can more be accelerated by identifying the positioning mark Speed, accurately determine some region for pattern after coding.Therefore, in a kind of possible embodiment, methods described is described Also include before pattern reconstitution steps：
Identify the positioning mark；
According to pattern after the positioning mark determination coding identified.
When there is provided need to the coding after pattern decode when, once detect it is described positioning mark, so that it may Using pattern after quickly determining a certain region as the coding, and by the pattern reconstitution steps code mask aliasing is solved by described After to the coding on the user eyeground on pattern.
In a kind of possible embodiment, the positioning is identified as the calibration maps being arranged on after the coding around pattern Case.For example, pattern is a rectangular area after the coding, the positioning is identified as positioned at described three or four tops in rectangular area The specific pattern of point.When pattern after user watches the coding, the inventive method can be quickly true by the positioning mark Pattern region after the fixed coding.
In an embodiment of the present invention, image or the user on user eyeground can be obtained by way of IMAQ The image of object in the visual field, then pass through image procossing (including the identification of pattern or the identification of positioning mark after coding recited above) Mode described image is analyzed and processed, obtain pattern after the coding on the image position (collection of image, And by image procossing come obtain position of the object on image can be by existing structure and technology in the prior art Solve, repeat no more here), project the solution code mask further according to the position of pattern after the coding on the image.But It is that, in order that the aliasing effect for obtaining the solution code mask and pattern after the coding is more preferable, the another kind of the embodiment of the present invention can Can embodiment in, the position of pattern after the coding relative to user can be first determined, further according to pattern after the coding The solution code mask is presented relative to the position of user.
In embodiments of the present invention, can by user's sight blinkpunkt relative to customer location detection determine described in The actual position of pattern after coding.
The mode of above-mentioned detection user blinkpunkt have it is a variety of, such as including following one or more：
I) optical axis direction of an eyes detected using a pupil direction detector, pass through a depth transducer again (such as infrared distance measurement) obtains the depth of eye gaze scene, obtains the blinkpunkt position of eye sight line, and the technology is prior art, Repeated no more in present embodiment.
