In specific application, the following two kinds mode can be selected to generate final watermark figure layer.First, the figure layer of creation can
To be blank figure layer, the blank figure layer itself has pixel value and transparency, by the watermark with pixel value and transparency
Content, which is covered to blank figure layer, can be obtained final watermark figure layer；Second, blank figure layer and watermark content are before superposition, no
Pixel value and transparency are limited, is adjusted after superposition to obtain final watermark figure layer.
S102, after watermark figure layer and image to be processed are carried out fusion treatment, fused image is obtained；Wherein, it merges
Image afterwards and the image to be processed distinct feature between the pixel at the corresponding position of watermark content.
Illustratively, above-mentioned image to be processed can choose solid color or the unconspicuous image of color change, that is, should be to
Handle each pixel in image pixel value is almost the same or pixel value between difference be less than certain threshold value.
Wherein, the first pixel and the second picture being respectively in watermark figure layer and image to be processed at same position
The process of vegetarian refreshments, above-mentioned fusion treatment includes:
According to the transparency of the first pixel, the pixel value of the pixel value of the first pixel and the second pixel, determination is melted
The pixel value of third pixel of the image at same position after conjunction.
Here, the fusion treatment in relation to watermark figure layer and image to be processed is mainly based upon the transparency of watermark content, right
The process that the pixel value of the pixel value of watermark figure layer and image to be processed is merged.In the embodiment of the present application, for watermark
It is respectively at for the first pixel and the second pixel at same position, can be determined in figure layer and image to be processed first
The pixel value and poor transparency of the product of the transparency of the pixel value of first pixel and the first pixel and the second pixel
Then above-mentioned two product is carried out summation operation, to obtain the third picture in blending image at same position by the product of value
The pixel value of vegetarian refreshments.Wherein, above-mentioned transparency difference can be the difference of the transparency of transparency threshold and the first pixel.This
Sample contains the characteristics of image of watermark content in obtained fused image, i.e., fused figure after carrying out fusion treatment
As with image to be processed between the pixel at the corresponding position of watermark content distinct feature.
It, can be logical to each color in the fusion of the pixel value for the pixel value and the second pixel for carrying out the first pixel
Road carries out pixel fusion, as shown in Fig. 2, above-mentioned pixel fusion method specifically comprises the following steps:
S201, it is directed to each Color Channel, determines the first pixel in the pixel value and the first pixel of the Color Channel
Transparency the first product and the second pixel in the pixel value of the Color Channel and the second product of transparency difference；
S202, first the second product of sum of products is summed, obtains third pixel in the pixel value of the Color Channel.
Here it is possible to determine pixel value and first pixel of first pixel in the Color Channel of watermark figure layer first
Transparency result of product (i.e. the first product), and determine picture of second pixel in the Color Channel of image to be processed
The result of product (i.e. the second product) of element value and transparency difference, then carries out summation operation for above-mentioned two result of product, i.e.,
It can determine fused image in the pixel value of the third pixel with watermarking images and image to be processed at same position.
Wherein, in the embodiment of the present application, above-mentioned image to be processed can be any required original desktop for showing user
Image, in this application scenarios of VDI desktop, which can be VDI desktop picture.
For a further understanding of the fusion for realizing watermark figure layer and image to be processed based on above-mentioned pixel fusion scheme, connect down
To combine a specific example and corresponding formula to be illustrated.
For watermark figure layer, the color with transparent channel can be carried out using RGBA value to be indicated, the watermark figure layer
Three Color Channels and a transparent channel are contained, for image to be processed, then color table can be carried out using rgb value
Show, there are three Color Channels for the image tool to be processed, in this way, after the fusion obtained for watermark figure layer and image co-registration to be processed
Pixel value of the image on three of them Color Channel can determine according to the following formula:
Wherein, R3, G3, B3 are used to indicate the third pixel of fused image in its R Color Channel, G Color Channel
With the pixel value on B color channel, R1 is used to indicate pixel value of the first pixel of watermark figure layer on its R Color Channel,
R2 is used to indicate pixel value of the second pixel of image to be processed on its R Color Channel, and G1 is for indicating watermark figure layer
Pixel value of first pixel on its G Color Channel, G2 are used to indicate that the second pixel of image to be processed to be logical in its G color
Pixel value on road, B1 are used to indicate pixel value of the first pixel of watermark figure layer on its B color channel, and B2 is for indicating
Pixel value of second pixel of image to be processed on its B color channel, α-A is for indicating transparency difference, and α is for indicating
Transparency threshold, A are used to indicate transparency of the first pixel of watermark figure layer on its transparent channel.
In this way, determining the first product according to R1*A, and after determining the second product according to R2* (α-A), can pass through
Summation operation, obtaining pixel value of the third pixel of fused image on its R Color Channel can also similarly determine
Pixel value of the third pixel of fused image on other two Color Channels, it is seen then that obtained fused image
In contain the characteristics of image of watermark content, so as to realize watermark parse.
In specific application, since client can be communicated by virtual protocol with virtual machine realization, in this way, remote service
The fused image that device can obtain fusion passes through VDI desktop (i.e. virtual machine desktop) display to client.
It is worth noting that in order to reduce influence of the watermark distinguishing characteristics to image to be processed as far as possible, it is above-mentioned transparent
Degree threshold value can be set to 1, in this way, can the transparency of the first pixel to watermark figure layer on its transparent channel carry out normalizing
Change processing obtains a transparency between 0 and 1 with processing, so that the characteristics of image for reducing watermark figure layer region is treated
The influence of image is handled, user is not noticeable.
In addition, when setting 1 for transparency threshold, for the Background From Layer region except watermark figure layer region,
It is set as all-transparent in the Background From Layer region, i.e., when transparency is 0, the image that can also further eliminate Background From Layer region is special
The influence to image to be processed is levied, so that only include characteristics of image relevant to watermark content in fused image, in order to
It is subsequent to carry out solution water mark operation.
For the ease of carrying out solution water mark operation, watermark adding method provided by the embodiments of the present application can also be to Background From Layer
Region carries out color setting, here it is possible to set single background colour, such as red, blue for Background From Layer region；May be used also
To carry out color setting to watermark figure layer region (i.e. the affiliated figure layer region of watermark content), here, in order to avoid image to be processed
Color caused by watermark content is interfered, the pixel value of each Color Channel in watermark figure layer region can be disposed as 255 (i.e.
The watermark content of corresponding white).In addition to this, it is contemplated that transparency of the first pixel of watermark figure layer on its transparent channel
A value between 0 and 1 after can be normalization, here, in order to meet above-mentioned watermark adding method in different application
Demand under scene, can be by 1/255~3/255, as the transparency range after normalization, in specific implementation, can be from upper
State the transparency of first pixel of the optional value as watermark figure layer in transparency range.
Here, the effect shown is hidden in the effect of watermark addition and watermark in order to balance, when carrying out watermark addition, usually
Several marks can be selected as watermark content, and watermark content can be set to entire image to be processed position more placed in the middle
It sets.
It is worth noting that above-mentioned this application scenarios of VDI desktop, watermark addition side only provided by the embodiments of the present application
A kind of exemplary application scenarios of method, in addition to this, the embodiment of the present application can also be applied to any required progress watermark addition

In order to carry out watermark parsing, the embodiment of the present application, can be by fused image after obtaining fused image
Subtraction is carried out with image to be processed, obtains error image, based on the pixel value of each pixel in the error image, is determined
Watermark distinguishing characteristics.Watermark parsing can be carried out based on the watermark distinguishing characteristics, is specifically retouched by following examples two
It states.
Embodiment two
As shown in figure 3, a kind of flow chart of the watermark analytic method provided for the embodiment of the present application two, for VDI this
For application scenarios, the executing subject of above-mentioned watermark adding method can be client, can also be the long-range of deploying virtual machine
The electronic equipments such as server, in order to ensure the administration authority of watermark parsing operation, the embodiment of the present application can select remote service
Device specifically comprises the following steps: as executing subject, the watermark analytic method
S301, image to be resolved is obtained；
Pixel in S302, traversal image to be resolved, using the pixel value of first pixel of traversal as reference image
Element value, and continue to traverse the pixel in image to be resolved, execute deterministic process: the pixel value for the pixel that judgement currently traverses
Whether the pixel value difference between reference pixel value meets distinguishing characteristics；
The pixel value of the pixel currently traversed is then adjusted to the default of watermark content by S303, if the determination result is YES
Pixel value, and continue to traverse the pixel in image to be resolved, deterministic process is executed, until after determining that judging result is no,
The pixel value for the pixel that reference pixel value is updated to currently traverse, and continue to traverse the pixel in image to be resolved, it holds
Row deterministic process；
S304, image after treating the pixel traversal in parsing image, after being parsed.
Here, for image to be resolved, remote server can treat parsing image solution watermark to obtain watermark information.It examines
Considering distinguishing characteristics related with watermark content in the embodiment of the present application can be based on fused image and image to be processed
Subtract each other, this part distinguishing characteristics can be used as the reference information of parsing watermark content.But it is to be resolved due to acquisition
Characteristics of image in image is obtained after fusion treatment in itself, the original image and watermark before uncertain fusion treatment
In the case where figure layer, when treating parsing image and being parsed as, the pixel value difference between neighbor pixel can be regarded to former
The difference of figure and image to be resolved between two pixels at same position, and then judge whether pixel value difference meets difference
Feature can filter out pixel relevant to watermark content in image to be resolved in this way, and then may be implemented pair
The parsing of watermark content.
In the embodiment of the present application, the solution water mark operation for treating parsing image can be realized by the way of pixel traversal.
In view of image to be resolved can be the image that above-mentioned watermark adding method generates, and use the image of watermark adding method generation
In, the position of watermark content addition, which usually can be, to be centrally positioned in original image to be processed, in this way, to be resolved
Image-region in image in addition to watermark content should be only including the corresponding image district of this background image of image to be processed
Domain.Therefore, in order to promote the accuracy of parsing, the embodiment of the present application can using the pixel value of first pixel of traversal as
Reference pixel value carries out pixel traversal.
In the embodiment of the present application, the image to be resolved that will be traversed first pixel (assuming that first reference image
Plain section be non-watermark region pixel) pixel value as reference pixel value after, second pixel point can be traversed, and pass through
Judge whether the pixel value difference between the pixel value and reference pixel value of the pixel currently traversed meets the judgement of distinguishing characteristics
As a result determine whether second pixel point is corresponding with watermark content；If so, the pixel value of second pixel point is adjusted to
The presetted pixel value of watermark content, and it is still based on above-mentioned reference pixel value traversal third pixel, likewise, for third
Pixel can also execute above-mentioned deterministic process, successively traverse；If it is not, then needing that reference pixel value is first updated to second
The pixel value of a pixel, then the traversal based on updated reference pixel value progress third pixel, successively traverse,
Until being completed being traversed to each pixel, the image after parsing can be obtained.
It is worth noting that above-mentioned ergodic process can be positive traversal (as used first left and then right, first up and then down traversal
Mode), it is also possible to reversely traverse (as using first right rear left, the traversal mode to get on, get off), for one by N number of pixel
For the image to be resolved of composition, forward direction traversal can be traversed from the 1st pixel of image to be resolved, at this moment, can be with
First using the pixel value of the 1st pixel as reference pixel value, the 2nd pixel of progress whether be watermark content judgement, according to
Secondary traversal, until traversing n-th pixel from the 1st pixel, reversed traversal then can be from the n-th picture of image to be resolved
Vegetarian refreshments is traversed, and at this moment, can carry out the N-1 pixel first using the pixel value of n-th pixel as reference pixel value
Whether be watermark content judgement, successively traverse, until from n-th pixel traversing the 1st pixel.
It is of course also possible to use the mode for traversing or traversing line by line by column, distinguishes successively the pixel of every row or each column
Ergodic process is carried out, in this way, for the 1st pixel traversed as reference value, with elder generation with the pixel value of the 1st pixel
As reference pixel value, carry out the 2nd pixel whether be watermark content judgement, successively traverse, until from the 1st pixel
Traverse the row or the last one pixel of the column.
In the embodiment of the present application, in order to further enhance the accuracy of watermark parsing, it can be traversed in conjunction with forward direction and reversed
The image after finally being parsed is traversed, or combines and traverses and traverse by column the image after finally being parsed line by line.Consider
