For example, the recovery pattern 150 obtained in Fig. 3 e can analyze, it is necessary to be presented to user information be " A ", because This can according to it is described recovery pattern 150 obtain one strengthen template so that the enhancing template be added to recovery pattern on after, with The corresponding pixel of information " A " is darkened, and the corresponding pixel of the background parts in addition to " A " is highlighted, so that user can be with See clearly " A ", improve the visual experience of user.

In one embodiment, the size and in the same size, the step of pattern after the coding of the solution code mask Rapid S120 is further to set the solution code mask and 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, mix, 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, for example, passes through United States Patent (USP) US7706025B2 When the striped solution code mask of middle announcement is decoded 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, coded treatment, pattern after being encoded are carried out by an encoder to a master pattern.

In embodiments of the present invention, the encoder includes an at least coding templet；

In the pattern coding step, coding templet described in one and the master pattern aliasing are obtained and schemed after the coding Case.

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 mixed pixel by pixel with the master pattern, it is overlapping, that is, pass through compile Each pixel on code mask enters line aliasing to corresponding pixel on the master pattern and obtains the pixel after corresponding aliasing, this Pixel after a little aliasings constitutes pattern after the coding.Certainly, those skilled in the art is it is recognised that the master pattern has A part for the larger pattern may be embedded in a larger pattern or be, at this point it is possible to only in the larger pattern The master pattern carries out the coded treatment, and 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 likely to be by an encryption algorithm to institute State master pattern and carry out coded treatment, obtain pattern after the coding.For example by a coded sequence to each of master pattern Pixel 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 in RGBA color space（Red, green, blueness, transparency）Passage；Or C, M, Y, K in CMYK color space（Cyan, magenta, yellow, black）Passage etc.）In one or more compositions.

In embodiments of the present invention, the solution code mask is a decoding pattern.The decoding pattern is each by a color space One or more compositions in passage.

In embodiments of the present invention, the coding templet is conciliate code mask and can obtained by following two method：

1）The coding templet is obtained first, and corresponding solution code mask is then generated according to the coding templet；

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, the coding templet is generated by a pseudo-random sequence, with significantly more efficient hidden Hide information in the master pattern.

Now, methods described typically also includes：

Template generation step is decoded, the solution code mask is generated according to coding templet correspondence.

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 decoding patterns after coding, obtain described The information included in master pattern.Certainly, in alternatively possible embodiment, end can also be provided for described information by institute State encoder or coding templet is supplied to ustomer premises access equipment, ustomer premises access equipment generates the decoding mould according to the coding templet Plate.

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.

Now, methods described also includes：

Coding templet generation step, the coding templet is generated according to the solution code mask correspondence.

Wherein, the solution code mask can be generated in information providing end, can also be generated in user terminal.

In the present embodiment, for example, the coding templet can be obtained by the decoding template transformation.Wherein, it is described It is transformed to anti-phase processing or the anti-phase processing with compensation.By it is described solution code mask obtain coding templet the step of with above with The step of coding templet obtains solution code mask is similar, and here is omitted.

In some embodiments, it can be recognized and schemed after the coding according to the characteristics of image of itself of pattern after coding Case.In other possible embodiments, compiled to can quickly recognize that determination is described in follow-up corresponding decoding process Pattern after code, methods described may also include after the pattern coding step：

Positioning mark setting steps, set the positioning mark of pattern region after the mark coding.

When pattern is decoded after needing to the coding, once detect the positioning mark, it is possible to quickly Pattern after the coding is determined, and by pattern after solution code mask aliasing to the coding on the user eyeground.

In a kind of possible embodiment, the positioning is designated 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 designated positioned at described three or four tops in rectangular area The specific pattern of point.When user watches pattern after the coding, the inventive method can be quickly true by the positioning mark Pattern region after the fixed coding.

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, for example：

The solution code mask is directly projected to user eyeground so that solution code mask is mixed 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.For example an intelligent glasses, and the intelligent glasses are worn 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 functions.

Certainly, in a kind of possible embodiment, it is possible to both solved code mask to user eyeground projection one, and in user Another solution code mask is inserted in light path after eyes and decoding between pattern, by two ways simultaneously to pattern after the decoding Decoded.

Therefore, in a kind of possible embodiment of the embodiment of the present invention, the pattern reconstitution steps S120 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 S120：

The decoding is shown in information display step, the light path after the eyes and the coding of the user between pattern 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 projecting The mode on eyeground is mainly decoded by solving being superimposed for pattern after 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 select corresponding coding templet to conciliate code mask.Be given below respectively with this two The corresponding decoding of the mode of kind and the embodiment of coded system（In following embodiments exemplified by using RGBA color space）：

1）When the solution code mask is presented by way of information projection：

Assuming that eyes see piece image A, separately there is a width to project the image B on eyeground, then the figure that brain is actually obtained As C is exactly image B and image A superimposed image.Superposition Formula is as follows：

f(C)=f(B)+f(A)

The 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 master pattern S cataloged procedure using above-mentioned formula in embodiments of the present invention：

f(C)=f(P)+f(S)

Wherein P is coding pattern, and C is pattern after coding.

Decoding process to pattern after coding can be expressed as with similar：

f(C’)=f(P’)+f(C)

Wherein P ' is decoding pattern, and C ' is recovery pattern（Pattern after decoding）.C ' expression side can so be derived Formula is：

f(C’)=f(P’)+f(P)+f(S)

As long as energy rational structure coding pattern P and decoding pattern P ' cause

f(P’)+f(P)=c

Set up, user just can directly be seen that the master pattern S that reduced dynamic range is [0,1-c]（The dynamic range contracts Small master pattern S is the recovery pattern C '）.Wherein, c is the constant between 0 to 1, typically between 0 to 0.5.

If coding pattern P is set up by pseudo-random process（For example obtained by a pseudo-random sequence）As long as then passing through Equation below construction decoding pattern P ', it is possible to pattern C after the coding is decoded by way of the embodiment of the present invention：

f(P’)=c-f(P)

That is, when the decoding pattern P ' on pixel pixel corresponding with coding pattern P color component primary color value When sum is a constant, it is possible to pattern C after the coding is decoded by way of the embodiment of the present invention.

Certainly, those skilled in the art by pseudo-random process it is recognised that when setting up the decoding pattern P ' when, It can correspond to and obtain the coding pattern P.2）Insertion solves code mask in by the light path between eyes and recovery pattern When the solution code mask is presented in mode：

A kind of transparent image aliasing algorithm common at present is used for Alpha Blending algorithms：

Assuming that having piece image A, another transparent image B, then remove the image C for seeing image A, obtaining 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)

Wherein, the RGB component primary color value that f (x) is pixel x in an image, 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 a master pattern S can be expressed as by formula：

f(C)=(1-a)*f(P)+a*f(S)

Wherein, P is coding pattern, and C is pattern after coding, and a is the transparency of each pixel in coding pattern P.

Decoding process corresponding with above-mentioned cataloged procedure can be expressed as with similar：

f(C’)=(1-a’)*f(P’)+a’*f(C)

Wherein P ' for decoding pattern, C ' for restore pattern, a ' for decoding pattern P ' in each pixel transparency.So can be with Derive that the expression way for restoring pattern C ' is：

f(C’)=(1-a’)*f(P’)+a’*(1-a)*f(P)+a’*a*f(S)

If a*a ' can be kept for the constant of each pixel, as long as energy rational structure P and P ' causes

(1-a’)*f(P’)+a’*(1-a)*f(P)=d

Set up, user just can directly be seen that the master pattern S that reduced dynamic range is [0, a*a '-d].Wherein, d, a and A ' is constant, and a*a '-d value is between 0 to 1, typically between 0.5 to 1.

Assume that coding pattern P is set up by pseudo-random process in the present embodiment（For example obtained by a pseudo-random sequence）, As long as then by equation below construction decoding pattern P ', it is possible to pattern after the coding by way of the embodiment of the present invention C is decoded：

f(P’)=[d-a’*(1-a)*f(P)]/(1-a’)

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 has solution in the prior art, no longer describes herein.

From the above, it can be seen that in embodiments of the present invention, as long as one in known solution code mask and coding templet, just It can according to formula above correspond to and obtain another.Certainly, in addition to method described above, the embodiment of the present invention may be used also To obtain corresponding decoding or encoding template by other suitable algorithms.

In a kind of possible embodiment, certain can be recognized by picture characteristics of pattern itself after the coding etc. The pattern in individual region is pattern after the coding, for example by image analysis method determine the picture characteristics of a certain specific region with The picture characteristics of pattern is same or similar after coding.In certain embodiments, as described above, pattern after in the coding Around be provided with after positioning mark, can be by recognizing that the positioning mark more fast and accurately determine some region For pattern after coding.Therefore, in a possible embodiment, methods described also includes before the pattern reconstitution steps：
